BenQ W1500 1080p DLP Home Theater Projector

BenQ has been on a roll lately. Their W1070 and W1080ST, reviewed earlier this year, are both excellent projectors for home video and gaming. The BenQ W1500 can be thought of as a bulked-up version of the W1070, with a more flexible zoom lens, improved image quality, stereo speakers, and wireless HDMI.

That last feature is sure to raise a few eyebrows. Wireless HDMI makes ceiling mounting the W1500 a breeze, since the projector only needs a power cable connection and is otherwise cable-free. While the system has some limitations, it adds value to what is already a feature-packed budget powerhouse. The W1500 has an MSRP of $1,999 but is available for $1,599 from authorized resellers.

The Viewing Experience

Just looking at the case, the W1500 looks like a sleek, streamlined version of the W1070. The contrast trim on the top of the projector has been replaced with an all-white panel, while the sliding lens shift door is now a swing-open door with a push latch. The lens shift knob is now larger and easier to turn using just your fingers; the old knob required a screwdriver or a coin for easy adjustment.

The W1500 has a longer zoom range than the W1070 as well. Its 1.6:1 lens will produce a 100″ diagonal image from 7′ 9″ to 12′ 5″ throw distance, while the W1070’s 1.3:1 lens will project an image of the same size from 8′ 4″ to 10′ 11″. This means the W1500 is capable of projecting a larger image from a closer distance, which is useful for small rooms, or a smaller image from a farther distance, which can be helpful for ceiling mounts far from the screen.

The W1500 produces over 1700 lumens in Cinema mode with the lamp at full power. Strictly going by the numbers, that’s enough to light up a 180″ diagonal 1.3 gain screen at 24 foot Lamberts, well above the recommended 16 fL. Realistically, few people will want to use such a massive screen even if they could fit it inside their house, which is where Eco mode comes in. Eco reduces light output by 37%, making for a much more reasonable picture that is still plenty bright enough for big-screen use. Since Eco mode boosts estimated lamp life by 40%, most folks will want to opt for that setting. The projector’s extra brightness can come in handy when watching 3D.

Hooked up to a Blu-ray player, the W1500 produces an image that is clean and sharp, with sparkling highlights and deep, dark shadows. Color saturation is excellent thanks to the projector’s 6X speed, six-segment RGBRGB color wheel — and with no white segment, color brightness and white brightness are perfectly balanced, producing an image that appears natural and life-like.

The W1500 has full HD 3D capabilities, and can accept any of the standard HDMI 1.4 3D signal types. It also reportedly has limited support for frame-sequential 3D, though we did not have the opportunity to test this feature during our review. The W1500 uses DLP Link for synchronization, and it requires faster 144Hz glasses (not included).

Key Features

Image quality. The W1500 creates a great picture, without a doubt. Even straight out of the box, the W1500 produces a sharp, clean home theater image with great shadow detail and well-saturated color. Black levels are very good, and SmartEco lamp mode can make them better in some circumstances, much in the same way an automatic iris can improve on/off contrast. Frame interpolation smooths out motion without making film look like digital video.

WHDI. Wireless Home Digital Interface, or WHDI, is a specification for one version of wireless HDMI connectivity. While external kits are available, the W1500 has a receiver built in to the projector itself, while a transmitter comes in the box. Since you only get one port to work with, the optimal solution is to hook the WHDI transmitter to the video out port of your A/V receiver. The WHDI transmitter will send full 1080p in either 2D or 3D plus sound. As far as image quality over WHDI is concerned, we did see some occasional artifacts when using WHDI. Macroblocking sometimes appears when transmission range is too great or signal strength is otherwise diminished.

Customizable. The W1500 has three User memory settings, which makes it easier to adjust the projector for different types of viewing. The W1500 also has ISF Day and Night settings, though these are only accessible once the projector has been tuned by an ISF-certified calibrator.

Quiet fan. Fan noise on the W1500 is quite low, even with the lamp set at full power. Your perception of fan noise will largely depend on where you are sitting in relation to the W1500’s exhaust vent. Near that quarter of the projector’s front panel, fan noise is slightly louder. Once in Eco mode, though, the W1500 is as close to silent as a projector this bright can get.

SmartEco mode, which cycles lamp power in response to image brightness, is not a new concept; several manufacturers have been including similar features in their projectors for years. However, the SmartEco implementation on the W1500 is among the first to not include audible, distracting fan cycling.

Onboard sound. Dual ten-watt stereo speakers give the W1500 a powerful sound system compared to most other home theater projectors. Of course, this is partly because most home theater projectors over $1500 don’t include speakers at all, instead expecting you to have an external sound system. But the W1500’s speakers are of good quality and get very, very loud, making them an excellent choice for casual or portable use, say in a game room or over at a friend’s place for a sporting event. Our test sample had a volume scale from 0 to 10, and the speakers did not start distorting until level 8.

Good remote. We don’t typically comment on a projector’s remote control, since what we like might be someone else’s pet peeve. But the W1500’s slim, candy-bar style remote is easy to hold, easy to use, and its backlit buttons are easy to read in the dark. The red backlight isn’t obnoxiously bright, either.

Placement flexibility. With a 1.6:1 zoom lens and vertical lens shift, the W1500 has more placement flexibility than many of its DLP competitors. The vertical shift is somewhat constrained, in that it only allows for a 15% to 20% adjustment of the image’s vertical position, but it is better than not having any lens shift at all. The shift allows you to adjust the projector’s throw offset to anywhere between 3% and 14% of the image height above the lens centerline.

Frame interpolation. Frame interpolation, or FI, creates interstitial frames in a video signal to smooth out the judder associated with camera pans and fast motion. The W1500’s FI has three levels. Low is a subtle setting which smooths out motion without any hint of the digital video effect and is a good choice for film purists who still want to reduce judder. Medium shows a bit more digital video effect but has a commensurate increase in the amount of smoothing. High is a good choice when actually watching HD video, but many folks will find it too aggressive for 24p film.

No rainbows. Quite a few people see rainbows when viewing projectors with 2X-speed color wheels; fewer still see them when watching a projector with a 4X-speed wheel. The W1500 has a 6X-speed color wheel — meaning the projector is nearly rainbow-proof. The wheel has six segments: two each of red, green, and blue. This arrangement also ensures 100% color brightness and rich color saturation, both important to a natural home theater picture.

Epson PowerLite 955WH

Epson PowerLite 955WH WXGA 3LCD Projector

  • PROS

    Suitably bright for a small to midsize room. Native WXGA (1,280-by-800) resolution. 1.6X zoom. Near-excellent quality for data images. Better-than-typical video for a data projector.

  • CONS

    No 3D support.

  • BOTTOM LINE

    The Epson PowerLite 955WH WXGA 3LCD Projector delivers high quality for data images, with enough brightness for a small to midsize conference room or classroom.

Basics

Like the Epson 955W and the NEC NP-M311W, the 955WH is built around a three-chip WXGA LCD engine. That gives it the advantage of being guaranteed not to show the rainbow artifacts (flashes of red, green, and blue) that are always a concern with DLP-based projectors. It also ensures that it delivers the same color brightness as white brightness, which isn’t true for most DLP projectors, and which can affect both color quality and the brightness of color images.

The key disadvantage that grows from having an LCD engine is that, as with most LCD data projectors, the 955WH doesn’t offer the 3D support that you’ll find most DLP models, including, for example, the Acer S1385WHne, our top choice for a moderately priced short-throw WXGA projector for a small to midsize room. However, this won’t matter unless you need to show 3D material, which simply isn’t necessary for most data-projector use.

Setup and Brightness

The 955WH measures 3.5 by 11.6 by 10.6 inches (HWD) and weighs 6 pounds 6 ounces, which makes it light enough to carry with you. However, most projectors in this size and weight class wind up permanently installed or on a cart.

Setup is typical, with manual controls for the focus and 1.6X zoom. Image inputs on the back panel include two HDMI ports for computers or video sources, two VGA ports for computers or component video, and both composite video and S-Video ports. In addition, there’s a USB Type B port for direct USB display, a LAN port for sending images and audio, as well as for controlling the projector over a network, and a USB Type A port for reading files directly from a USB memory key or for connecting an optional ($99) Wi-Fi dongle. One of the HDMI ports also supports MHL.

According to the Society of Motion Picture and Television Engineers (SMPTE) recommendations, the 955WH’s rating makes it easily bright enough for a small to midsize room. Assuming a 1.0-gain screen, 3,200 lumens would be suitable for a 215- to 292-inch (diagonal) image in theater-dark lighting. With moderate ambient light, it would be bright enough for a 140-inch image. If it is too bright for the ambient light level at the image size you need, you can use one of the projectors’ lower-brightness preset modes, its Eco mode, or both.

Image Quality, Lamp Life, and Audio

Image quality for the 955WH is near-excellent for data images. The only issue worth mention that I saw with our standard suite of DisplayMate tests was a minor problem with color balance. In most of the predefined modes, the brightest gray levels show a slight tint relative to darker levels. This is only obvious with gray-scale images, however, and there are also modes that offer suitably neutral grays all the way from black to white. Colors in all modes are vibrant, eye-catching, and well saturated.

More important for most data images is that the 955WH maintains crisp detail across the entire screen. In my tests, for example, white text on black was crisp and readable at sizes as small as 9 points, and black text on white was highly readable even at 6 points.

Video quality is limited by the native 1,280-by-800 resolution, which translates to a maximum video resolution of 720p HD without scaling the image. Within that context, however, the quality is much better than is typical for a data projector. Contrast is a little low, which means you won’t mistake the image for something you’d expect from a home-theater projector, but the video is good enough to be watchable even for long sessions.

The 16-watt speaker offers good sound quality and enough volume to fill a midsize room. There’s also a stereo audio output you can use for an external sound system.

One important extra is a promised low running cost, with both a longer-than-usual lamp life, rated at 5,000 hours in Normal mode or 10,000 hours in Eco mode, and a far-lower-than-usual replacement cost, at $79. Another plus is a split-screen feature, which lets you see images from any two sources at once. You can toggle to and from split-screen mode with a single button press on the remote. You can also change sources on either side as needed, as well as choose between making the two images of equal size, or making either one larger than the other.

Conclusion

If you need 3D support, be sure to look at the Acer S1385WHne. If you don’t need 3D, however, the Epson 955W, the NEC M311W, and the Epson PowerLite 955WH WXGA 3LCD Projector are all worth considering, with similar levels of brightness, data image quality, and video quality. However, the 955WH is the only one of the three that offers MHL support, its audio quality is a bit better than the NEC model delivers, and it also offers the lowest running cost of the three. That trifecta puts it a step out in front, and makes it our Editors’ Choice.

Review Projector Acer H7550ST

  • PROS

    Native 1080p resolution. Bright. Short throw. 1.1x optical zoom. Supports 3D for video sources, like Blu-ray players. Comes with two pairs of 3D glasses. Short lag time. Three HDMI ports. Near-excellent video quality.

  • CONS

    Shows rainbow artifacts in video, particularly for black-and-white source material.

  • BOTTOM LINE

    Despite showing rainbow artifacts, the Acer H7550ST is a tempting choice as a home-entertainment projector, thanks to its bright image, a short throw combined with a 1.1x zoom, full 3D support, and a lag time that’s suitable for gaming.

The DLP-based Projector Acer H7550ST delivers a constellation of features—including 1080p (1,920-by-1,080) resolution, a 3,000-lumen rated brightness, and a short throw combined with a modest zoom—that make it a strong candidate as a home-entertainment or low-end home-theater projector. Its Achilles’ heel is that it shows rainbow artifacts just often enough that they could be annoying to anyone who sees them easily. However, it delivers otherwise high-quality video. For those who aren’t bothered by rainbow artifacts, the H7550ST is a tempting choice.

As with most of its close competition, including the Optoma HD28DSE and the Epson Home Cinema 2040 3D 1080p 3LCD Projector, which is our Editors’ Choice moderately priced 1080p home-entertainment model, the H7550ST is well suited for gaming, with a short lag time for a projector.

Compared with the Optoma and Epson models, the H7550ST is notably bigger and a little heavier, at 3.9 by 14 by 9.5 inches (HWD) and 7 pounds 8 ounces, which makes it more cumbersome to carry with you to a friend’s house for a movie night or gaming. However, it’s still small and light enough that if you don’t have room for installing it permanently, you can store it away and then set it up quickly and easily when you want to use it. Acer even supplies a soft carrying case with reinforced side panels.

Setup

Setup is a little unusual for a short-throw projector. Most short-throw models don’t offer any zoom, which means you have to move the projector when you want to adjust the image size. The H7550ST’s 1.1x zoom gives you some flexibility for exactly how far to place it from the screen for a given size image. However, the cost of this added convenience is that even at its maximum zoom setting, the H7550ST has a longer throw than most short-throw models.
For most of my tests, I set the lens to its maximum zoom setting and used a 90-inch image (measured diagonally) at the native 16:9 aspect ratio, which put the projector 53 inches from the screen. As a point of comparison, the Acer H6517ST, which offers a short throw without optical zoom, delivers the same size image at 38 inches from the screen.

In most other ways, setup for the H7550ST is standard. Choices for image input on the back panel include two HDMI ports, a VGA port, both composite and S-Video ports, and three RCA connectors for component video. As with an increasing number of projectors today, there’s also a third HDMI port in a hidden compartment at the right-front-top section of the projector. The hidden port is meant for a streaming wireless adapter, should you want to use one. Both it and one of the HDMI ports on the back also support MHL.

The H7550ST can also be used with Acer’s WirelessHD Kit ($199), which integrates nicely with the projector. The optional kit includes a transmitter that you connect via HDMI cable to an image source and a receiver that plugs into one of the projector’s HDMI ports.

When the receiver is plugged in, the H7550ST automatically replaces the appropriate HDMI option on its source menu with a WirelessHD option. Choose it, and if the WirelessHD connection isn’t already established, you’ll see step-by-step setup instructions on the screen. The instructions basically tell you to connect the transmitter, plug in its power adapter, and turn it on. Not only is the WirelessHD easy to set up, but it worked flawlessly in my tests, with no noticeable difference between using it and connecting via HDMI cable instead.

Brightness

As with any single-chip DLP projector, discussing the H7550ST’s brightness gets a little complicated, because of differences between white brightness and color brightness. Briefly, unlike three-chip LCD projectors, which have the same brightness level for both, most DLP projectors deliver a lower color than white brightness, which can affect both color quality and the brightness of color images. The difference in the two levels means that the 3,000-lumen rating for the H7550ST may or may not translate to a brighter full-color image than you’ll get with an LCD projector like the Epson 2040, which has a lower rating, but has the same color as white brightness. (For more on the topic, see Color Brightness: What It Is, Why it Matters.)

As a reality check, in my tests in theater-dark lighting, the H7550ST was too bright at its brightest setting for the 90-inch image that I used. I had switch to Eco mode to find a comfortable level. You can also lower the brightness by choosing one of projector’s predefined lower-brightness settings or by turning off the DLP Brilliant Color feature. Both choices have the added benefit of improving color quality as well.

Performance

Image quality for 2D video is near excellent, at least in Movie and Dark Cinema modes, which offer the best color quality. The brightest mode had a green tint in my tests, which is a common issue for projectors, and some colors in each of the two brightest modes—Bright and Standard—were dark in terms of a hue-saturation-brightness color model, which is expected for projectors with a significant difference between white and color brightness.

Beyond that, the projector did a near-excellent to excellent job on our tests with shadow detail (details based on shading in dark areas). I also didn’t see any motion artifacts or posterization (shading changing suddenly where it should change gradually), even on test clips that tend to cause those problems. I saw some moderate noise in video clips that tend to show noise, but not enough to be an issue for most people.

The H7550ST also does a better job of avoiding rainbow artifacts than many DLP projectors, but it still shows some. I saw them often enough in my tests that anyone who sees them easily will notice them, and may find them bothersome, particularly with black and white source material.

Image quality for 3D video is also near excellent. For those aspects of image quality that both 2D and 3D share, the quality was similar in my tests. I didn’t see any crosstalk, and I saw only a hint of 3D-related motion artifacts. A notable extra for the H7550ST is that it comes with two pairs of DLP-Link glasses. Most projectors don’t come with any.

Acer H7550ST

Two other pluses are the H7550ST’s stereo sound system and short lag time. The two 10-watt speakers offer good sound quality, with enough volume to fill a small family room. If you want better quality or higher volume, you can connect an external sound system to the audio output, or use the built-in support for Bluetooth to connect to headphones or speakers. Gamers will appreciate the short lag time, which I measured, using a Leo Bodnar Video Input Lag Tester, at 34 milliseconds (ms), or a two-frame lag at 60 frames per second.

Conclusion

Be sure to consider the Epson 2040 for its guaranteed rainbow-free images, particularly if you see rainbow artifacts easily and expect to watch much black-and-white source material. Also worth looking at is the Acer H6517ST, which has an even shorter throw than the Acer H7550ST. That said, if you don’t see rainbow artifacts easily or don’t find them annoying, the Acer H7550ST offers a short lag time for gaming, an eminently usable sound system, and a bright image, with near-excellent image quality. Although it costs a little more than the competition, it largely justifies the price by adding a zoom to the short throw, and bundling in two pairs of 3D glasses.

Review Projector BenQ MW705

  • PROS

    WXGA (1,280-by-800) native resolution. Bright 4,000-lumen rating. Light enough to carry with you. Near-excellent image quality for data images. Hidden compartment for wireless streaming module.

  • CONS

    With data images, some colors are a little dark. Shows rainbow artifacts with full-motion video. Weak audio.

  • BOTTOM LINE

    Bright enough for a midsize room and light enough to carry easily, the BenQ MW705 projector will be of particular interest to anyone who wants to take advantage of its hidden compartment for a wireless streaming module.

Rated at 4,000 lumens and weighing 6 pounds 10 ounces, the BenQ MW705 is bright enough for a midsize room and light enough to tote easily. Like a growing number of projectors, it also features a hidden compartment for a wireless streaming module, if you want to add one. The combination of light weight and the hidden compartment, which gives you a convenient place to connect the module permanently, helps make the projector particularly attractive for anyone who wants the convenience of quick, cable-free setup with mobile devices, including laptops.

Brightness

As always with DLP projectors, brightness comparisons are a little complicated. Both Epson models are built around three-chip LCD engines, which ensures matching levels of color and white brightness. In contrast, both the MW705 and the Ricoh WX5460—like most single-chip DLP data projectors—have a lower color than white brightness. The difference in the two levels means the MW705 won’t be as bright for full-color images as you would expect from the white brightness.

Keeping that qualification in mind, and strictly as a point of reference, according to the Society of Motion Picture and Television Engineers (SMPTE) recommendations, the 4,000-lumen rating for the MW705 should make it bright enough in theater-dark lighting for a 241- to 326-inch image (measured diagonally) at its native 16:10 aspect ratio and assuming a 1.0-gain screen. With moderate ambient light, the appropriate size drops to 160 inches. For smaller screen sizes, you can lower the brightness level by using one of the projector’s lower-brightness predefined modes, its Eco mode, or both.

Rainbow Artifacts and 3D

One of the key disadvantages of single-chip DLP projectors is that, unlike three-chip LCD projectors, they can show rainbow artifacts (red-green-blue flashes). That’s at least somewhat balanced by the advantage that most offer 3D support, which is rare for LCD data projectors.

In my tests, the MW705 showed rainbow artifacts infrequently enough with static data images that it’s unlikely anyone will find them bothersome. The only time I saw any was with one image that’s designed to bring them out. With full-motion video, however, they showed often enough that anyone who sees them easily may find them annoying. That makes the projector suitable for showing video clips limited to a minute or two at most.

If you need 3D, the MW705 supports all HDMI 1.4a 3D formats, using DLP-Link glasses only. However, this won’t matter in most cases, since few people need 3D for data projector applications.

Hidden Compartment and Setup

The hidden compartment for the wireless module is on the MW705’s upper side on the back left. The cover, which is held on by a screw, lifts off to reveal an HDMI port. Unlike similar compartments on some other projectors, there’s no USB Type A port in the compartment for providing power. However, the HDMI port is MHL enabled, which means it will work with any device that can get power over MHL, including the BenQ QCast Wireless Streaming module ($59).

Hidden compartments for wireless streaming modules are showing up on more and more models. However, the MW705 adds a notable convenience that we haven’t seen on other projectors: One of the image source buttons on the remote is labeled QCast, which means you can switch to your wireless module by pressing a single button on the remote. According to BenQ,the QCast button will switch to any streaming module you choose to connect to the hidden HDMI port, QCast or not.

The compartment can be particularly helpful for portable use. If you set up your projector and mobile device to connect directly using the module, setting up on the road will be quick and easy, with the module already plugged in and no need to connect a cable. Alternatively, if you set the projector up in one room permanently, it provides a convenient place to store the module. Needing a screwdriver to remove the cover also offers some modest protection against someone walking off with it.

Setup is otherwise standard, with a manual focus and manual 1.1x zoom. Image inputs on the back include a second HDMI port, one VGA port for a computer or component video, and both composite and S-video ports. There’s also a USB Type A port, but it’s strictly for providing power. The HDMI port on the back does not support MHL.

Image and Audio Quality

The MW705’s quality for data images is near excellent overall. On our DisplayMate tests, some colors were dark in terms of a hue-saturation-brightness model with every preset mode, that that’s expected for projectors with a lower color than white brightness. Color balance was excellent, with suitably neutral grays at all levels from white to black in every preset mode.

More important for most data images is that the MW705 does a good job holding detail. With text, for example, white text on black were highly readable at 9 points in my tests and black text on white were crisp and readable at 6.8 points.

With full-motion video, the MW705 delivered near-excellent color quality in my tests with good to excellent shadow detail (details based on shading in dark areas). However, long video sessions are still best avoided, since there may be people in your audience who see rainbow artifacts easily and find them annoying.

The audio system, built around a 2-watt mono speaker, is severely underpowered for this bright a projector. The sound quality is more than acceptable, but it doesn’t fill even a small room. If you need sound, plan on connecting an external sound system to the stereo audio output.

WHAT IS THE EPSON EB-U04?

The EB-U04 is an LCD projector with a Full HD resolution. Epson pitches it as a projector that can be used for either home entertainment or office presentations.

EPSON EB-U04 – DESIGN AND FEATURES

While it isn’t outright ugly, chiefly thanks to its glossy white top cover, the EB-U04 looks a bit utilitarian versus the more living room-friendly Epson EH-TW5300 that I tested recently. It’s smaller and squat, with a noticeably more compact lens – none of which raises great hopes about its picture quality versus the EH-TW5300.

Its relatively petite size does make it handily portable, though – and this useful trait is enhanced by the inclusion of a padded carry bag with the projector.

Connectivity is pretty good. Two HDMIs back up its home-entertainment claims, while its potential as a workhorse is enhanced by a USB port capable of playing multimedia files, a VGA PC input, and the ability of one of the HDMIs to handle MHL mobile phone playback.

You can even add an optional wireless adapter (the ELPAP10), which opens up the potential for using Epson’s iProjection app to stream a range of content – including photos, videos and documents – directly from your mobile phone or tablet through the projector.

The projector’s key picture specifications include a native Full HD resolution, a claimed dynamic contrast ratio of 15,000:1, and a very high maximum brightness of 3,000 lumens. On paper, this combination of brightness and contrast seems weighted towards the business market rather than home-cinema, but it’s entirely possible that the EB-U04 will have the controls necessary to adapt its optics to suit both movie and PC content.

For those looking for a projector for home use, there’s one other point of concern. For while I described the projector as “Full HD”, its resolution is in fact 1,920 x 1,200 rather than 1,920 x 1,080. This means it has a PC-friendly 16:10 native widescreen aspect ratio rather than a video-friendly 16:9 one.

Epson EB-U04

As you’d expect, the projector carries the option to show 16:9 widescreen sources in their native ratio; you don’t have to see them stretched vertically to fill the EB-U04’s full resolution. But there’s no getting round the fact that 16:10 image clips are designed for PC rather than video use.

With the EB-U04 potentially getting used at work and home, it’s good to find Epson claiming a huge lamp and filter life of 10,000 hours – roughly enough to deliver one movie a day for 15 years!

Note, though, that to achieve this life span you’ll need to keep the projector running in its reduced brightness Eco mode. This may not necessarily be possible if your office or home environment has much ambient light.

On a positive, I should remind that this LCD projector won’t suffer with the rainbow striping problem common with rival DLP technology. In addition, it should also deliver more bright images more consistently because, unlike DLP technology, LCD projectors don’t use a colour wheel to produce.

On the flip side, the EB-U04’s LCD technology will lead to a reduction in image quality over the projector’s life than you’re likely to see with a DLP model.

Acer K335 Projector Overview

The Acer K335 projector is a WXGA (1280 X 800) DLP projector that offers an increase in light output from the earlier Acer K330 model.  The K335 has  a similar size, weight and control layout as the K330.  However, the new model has a somewhat different front panel layout for the lens and IR remote sensor while the rear panel connector layout is very similar to the earlier model  The K335 is rated to 1000 lumens, which is double the rated light output of the earlier K330 model.  In our tests neither the K330 nor the K335 were measured to produce the manufacturer’s rated light output, but the K335 is significant brighter than the K330, as well as producing more lumens of light output than most other competitors LED portable/pocket projectors.  This makes the K335 a very versatile pocket projector that offers adequate light output to deal with less than ideal lighting conditions.  The K335 LED light source is rated to last 20,000 hours, which is typical for recent LED-based portable projectors.  The K335 has a fixed lens, with no optical zooming or optical lens shift.  It does offer a digital zoom function but this simply enlarges a portion of the image and is not a substitute for an optical zoom lens.  As a result, the K335 will need to be  placed at the proper distance from the screen in order to obtain the image size desired.  Also it will need to be positioned at the proper height relative to the screen, if use of digital keystone correction is to be avoided.  When the ideal projector height (relative to the screen) cannot be provided the K335 has very good automatic digital keystone correction to facilitate setup.  The works thru the K335 having an internal tilt sensor that applies the correct amount of keystone correction within a couple of seconds after the tilt of the projector is changed.  The K335 has a throw ratio of approx. 1.25:1 meaning with a projector-to-screen throw distance of 8 feet (96 inches) the image will be about (96/1.25=) 76 inches wide.  Note this the width of the image and not the diagonal size.  The K335’s rear panel offers connection for the most common video inputs, including HDMI, VGA and composite video as well as an analog audio input.  It can also project from a USB thumb drive, an SD card, from an iPad /iPhone (w/ iOS 5.0 or later and with optional adapter), or from Android tablets/phones (w/ Android 4.0 or later).  The K335 has provisions for displaying not only photos, video and audio files directly from a USB or SD memory card, but the K335 can also display Microsoft Office documents.  This capability for PC-free presentations could be a useful feature on a portable mini-projector for the ‘road warrior’ that likes to travel light

There is also a built-in three watt speaker that is adequate only for small rooms, but fortunately, there is also an audio output jack for use with amplified external speakers. The K335’s light weight and compact size makes it a good choice for traveling.  Like many other small, portable projectors the K335 does not have a battery option, but with the relatively high light output of the K335, a battery option is probably not feasible.  Unlike some other small portable projectors, the K335 has its power supply is built in, so it only uses a standard power cord, thus improving its portability.  The K335 also comes with a nice carrying case with a front pocket just large enough to accommodate the remote control, power cable and a couple small accessories (e.g., memory card, HDMI cable).  The Acer K335’s combination of fairly high light output (for this class of projector), decent contrast, acceptable color accuracy, long LED light source life, and modest price will appeal to those in the market for a pico or pocket projector for business use, but need more lumens of light output than is found in many projectors in this class.


Acer K335 Special Features

20,000 Hour LED Life – The Acer K335 uses an LED light source that is rated to last 20,000 hours.  This is likely longer than the life of the projector

Presentations from USB flash Drive, SD Card, iPhone/iPad/iPod or Android tablet/phone – The Acer K335 has built-in ports allowing for presentations from a USB flash drive or SD memory card.  Through the use of an optional adapter, the Acer K335 can present photos and videos from iPhone/iPad/iPod or from an Android tablet or phone.

Display of Microsoft Office Documents -The K335 can directly accept Word, Excel and Powerpoint files from a SD memory card or USB drive and project the contents of the document.  The allows for MS Office documents to simply be loaded into the projector from a flash memory drive (USB or SD card) without the need to connect a PC to the projector.  The Acer documentation does not specifically indicate which versions of MS Office documents are supported.

Game Ready – The Acer K335 has ‘Game’ mode and along with a relatively short lag time make this model suitable for gaming.

3D Ready – The Acer K335 is 3D ready via its implementation of DLP Link.  It can only accept 3D from a suitably equipped source (e.g., PC) that is capable of providing 3D in a alternating frame mode.   The K335 is not compatible with the most common 3D video signal formats that are used with Blu-ray Discs and for 3D channels distributed by satellite or cable TV services.  The 3D capabilities of the K335 were not evaluated for this review.

Support for Wireless Input – The K335 supports a WiFi input with the addition of an optional Wi-Fi adapter.  The Acer Wi-Fi adapter was not provided with the review unit and as a result the Wi-Fi capabilities of the K335 were not evaluated for this review.

WHAT IS THE BENQ W3000?

The 64,900 THB W3000 is the second projector I’ve seen from BenQ to use the brand’s new Cinematic Color technology, for accurately hitting the Rec. 709 video standard right out of the box. It uses better lens glass than the previous model, BenQ W2000 projector, I tested recently; adds horizontal as well as vertical optical image shifting; introduces motion interpolation processing; offers more optical zoom; and ships with a pair of 3D glasses.

 

BENQ W3000 – DESIGN AND FEATURES

The W3000 doesn’t follow the design sported by the new W2000 and W1110 BenQ projectors. Instead, its angular, top-heavy style is more akin to BenQ’s 2015 home entertainment range. It isn’t unattractive – especially with the silver fascia contrasting so tastefully with the gloss white of the projector’s other sides – but it does make you wonder if this model is actually built on an older chassis design than the W2000 and W1110.
BenQ W3000

The W3000’s rear is crowded with connections. Among the highlights are two HDMIs, a D-SUB PC port, and RS-232 control port, a component video input, a composite video input, a 12V trigger output, a stereo audio input and a 3D Sync output.

The projector features a built-in 3D transmitter, which you can take advantage of from the get-go thanks to a single pair of active-shutter glasses included in the box – provided you’re actually interested in 3D, of course!

You can also get an optional wireless HD system for the W3000, which would enable you to transmit HD video from source to the projector.

The W3000’s basic picture specifications find it rocking a Full HD single-chip DLP engine capable of hitting a peak brightness of 2000 lumens and a contrast ratio of 10,000:1. This contrast figure is slightly down on the W2000’s 15,000:1 – although as noted in the introduction, the W3000 certainly makes up for this in the form of some extras that the W2000 lacks.

Heading up the feature list is the Cinematic Color system. First seen on the W2000, this technology claims to deliver a picture that gets very close to the Rec. 709 video industry standard right out of the box.

It’s built around a series of manual calibrations of every W3000 on the production line; software optimisation of the blacks, whites and greys; plus a specially angled 6x speed RGB colour wheel, which has been coated in a new type of phosphor found to deliver the most accurate colour results.

Cinematic Color did a very credible job on the W2000, so there’s no reason to assume it won’t be at least as useful on the W3000.

BenQ W3000

Also carried over from the W2000 is BenQ’s surprisingly effective CinemaMaster audio system. Here, the combination of 10W speakers housed in resonant sound chambers with powerful audio processing delivers a powerful yet effectively dispersed soundstage than anything you’d usually hear from built-in projector audio systems.

One of the W3000’s key features over the W2000 is Motion Enhancer processing, which can interpolate extra frames of image data to reduce common projection issues such as jitter, blurring and image lag. Some will argue that this feature is at odds with the Cinematic Color tool, given that the sort of film fan most likely to embrace Rec. 709 accuracy won’t be inclined to use motion processing. Personally, though, I’m happy to keep an open mind – for now.

The W3000’s video processing also includes “enhancers” for both colour, detail/sharpness and flesh tones. Again, these are arguably at odds with the Rec. 709 idea, but I’ll refrain from making a prejudgement.

BENQ W3000 – PICTURE QUALITY

Prior to testing the W3000, I’d feared that it wouldn’t offer enough of a step up on the BenQ W2000 to justify the price bump. But, the W3000 subtly improves on the previous model in a number of picture areas, adding up to an overall step up in performance that makes it well worth the extra outlay.

For starters, the W3000 is capable of producing deeper black levels than the W2000, leaving less greyness hanging over dark scenes so that they look instantly more immersive and cinematic.

The enhanced black-level response also means, critically, that you can see far more detail in dark areas. In fact, for me the W3000 is in a class of its own in this price bracket of the market. In terms of contrast and shadow detail handling, it reveals subtleties and a sense of depth during dark scenes that other, similarly affordable projectors just can’t deliver.

 

It’s great, too, to see the projector’s rendition of black colours looking so neutral, with no infusion of the blue or green undertones that affect lesser projectors.

The W3000’s deft shadow detailing also means that dark scenes look far more “equal” of bright scenes than is usually the case with affordable projectors, making for a more consistent viewing experience with films that regularly shift between dark and light scenes.

Dark scenes also seem slightly less infiltrated by the gentle green speckling noise associated with single-chip DLP projector systems. Nor is there any sign of the fizzing noise over moving skin tones that was once a common flaw with single-chip DLP projectors.

Actually, the W3000’s pictures in general are startlingly free of almost all types of noise – I’ll come to the exception to this later.

Even natural grain in films such as 300 and Harry Potter and the Deathly Hallows prove no challenge to the W3000’s optics and processing. It’s even possible to run the motion processing on its low level without grain starting to look forced and unnatural.

BenQ W3000

I’m not implying here that the W3000’s pictures are in any way soft. On the contrary, they do a brilliant job of bringing out every pixel of detail, texture and definition from a good-quality HD source. The point is that they do so naturally, without looking processed and without revealing any hint of the DLP chipset’s pixel structure.

And now to what movie fans will actually consider the W3000’s crowning glory: its excellent colour handling. Using the Cinema picture preset with minimum manual adjustment, colours look gorgeously natural in terms of both the natural feel to their tones and the outstanding subtlety with which even the finest blends are handled. This means there’s pretty much zero striping or blocking, even over tricky skin tones.

The tonal balance is immaculately judged too, with no hue standing out unnaturally above the rest. As a result, you always take in the image as a whole rather than having your eye drawn to specific areas of exaggerated colour.

Actually, the precision of the W3000’s colour handling is also the reason behind its images looking so detailed and full of depth.

BenQ W3000

Movement in the frame is handled well even if you don’t use the W3000’s motion processing system. And finally, it’s important to stress that despite the impressive black-level response and focus on accurate colours, pictures still look bright and punchy.

I have only a couple of issues with the W3000’s pictures. First are some brightness uniformity errors – but nothing that shows up often with regular video, rather than uniformity test signals. Second are the occasional traces of DLP rainbow noise: stripes of red, green and blue flitting over really bright highlights of the picture.

The rainbowing isn’t something that you witness routinely; it’s visible only over small, extremely bright image highlights when they appear against dark backdrops. Also, it’s reasonably subdued. However, if you’re one of those people who’s particularly sensitive to seeing it, it’s definitely something of which you should take note.

BENQ W3000 – SOUND QUALITY

There was a time when reviewing the sound quality of a projector – assuming it had speakers built in at all – was a pointless task; the majority sounded uniformly poor. Recently, though, this has started to change.

The W3000 plays its part in this shift by delivering a soundstage that offers more clarity, detail and distortion-free volume than you’d ever expect a projector to manage.

Inevitably, it isn’t perfect. Bass sounds pretty boxy, and the soundstage doesn’t project as far from the projector’s body as I’d like. If the projector is sat some distance from your screen, then you’ll likely be rather distracted by the dislocation between the image and the source of the sound. These sorts of issues are pretty much par for the course with integrated projector audio solutions, though.

A less typical issue noted with the W3000, though, is a tendency for its audio to appear slightly out of sync with lip movements in its images. I suspect this is related to the input lag issues (discussed below). If this is the case, the only way to get round it until BenQ finds a permanent fix is to run the audio through an AV receiver that lets you add delay to the audio stream.

SHOULD I BUY A BENQ W3000?

If you’re a movie fan then you’ll struggle to find better picture quality in a projector that costs less than 64,900 THB

However, if you’re likely to be gaming on your projector as well as watching movies then the W3000’s problems with input lag mean you’d be better opting for BenQ’s W2000. Unless, of course, BenQ comes up with a solution to the issue, which is a possibility.

The Technology of Home Theater Projectors and Systems

HOME THEATER PROJECTOR BRIGHTNESS, ZOOM LENSES AND THROW DISTANCES

What’s this all about?

When shopping for your home theater projector, of course brightness – lumens, are one of the most obvious specs you see. The interesting thing, is that depending on how/where you set up your projector, brightness can vary by almost double!

That’s right – a projector placed in one position in your room, might do 350 lumens, but placed more optimally, it could produce as much as 700 lumens. Sound easy? Not! There are always trade-offs. Before I get into all of this, let’s be clear up front:

The purpose of this piece is to improve your understanding of the impact of positioning a projector, the lens it has, and your need for achieving a level of brightness. While the information here, may cause you to change some of your installation assumptions, it is unlikely that you will make totally different choices in projector, screen type, or whether you ceiling mount or shelf mount a projector. These decisions will all have some, but minor impact on your overall theater, and its performance.

OK, back to brightness, first, this two to one range of brightness isn’t true for all projectors. The huge shift in brightness occurs with projectors that are exceptionally flexible in placement, by virtue of wide range zoom lenses.

When a projector’s lens is in full wide angle mode (largest image from a given distance), more lumens make it out the lens. In full telephoto, less lumens.

Many projectors for the home, (mostly 3LCD and LCoS types) now offer 2:1 zoom lenses. That is a placment range from closest to furthest, of 2 to 1. Perhaps, for a 100″ diagonal 16:9 screen, that might be from 10.5 feet to 21 feet away.

If you mount it 10.5 feet from the screen, you will get almost double the lumens as mounting it 21 feet back.

There is no straight simple formula, because different lens designs will have some impact on the actual amount of change, but, let’s say that with a 2:1 lens, it will be close to a doubling.

If, on the other hand, the projector has a far more limited lens, say with a zoom ratio of 1.2:1, then, the change in brightness from one “extreme” to the other, becomes minimal, and not a serious consideration.

Now, most of the DLP projectors have limited zoom lens (1.1:1 to 1.3:1), so there isn’t much to concern ourselves there, but with the 3LCD, and LCoS projectors, where all of them seem to have at least 1.5:1, and most are around 2:1, where you place the projector can matter a lot.

Consider, the reason you get a 2:1 zoom on most of these projectors, is to allow the flexibility not just to ceiling mount the projector, but to give you the option of mounting the projector on the rear wall of your room. The projectors with wide range zoom lenses means that probably 90+% of people can rear shelf mount.

And, rear shelf mounting can save money, in terms of length of cables as well as installation costs – as it’s harder to get power to most ceilings, and if you have fairly high ceilings, working up there means ladders or scaffolding. For most, shelf mounting is just plain simpler and less expensive.

For most people that are shelf mounting their projectors, they will find their zoom lens nearer to the middle of the zoom range, or further back. As a result the actual brightness will probably be a little less than we quote, since we measure with the zoom at mid range.

The only reason this may be important, is for discussions of what is bright enough to meet your needs, screen size, type, etc.

If getting more lumens tempts you to ceiling mount, no problem at all. You get to enjoy any extra brightness. Of course there are trade-offs to everything. The closer the lens to the screen, the more optical distortion in the ends and corners (I’m talking very, very minor stuff). There will also be a smaller “sweet spot” for sitting, with higher gain screens. For that reason, as an example, Stewart FilmScreen’s Firehawk (which I own), comes in two versions, one for closer in positioning of the projector, and that one has less gain (less brightness back to your eye). Again, its another small difference, but a consideration if you are being thorough. Interesting – you mount closer for more brightness, but then need a screen that is less bright to maintain a wide viewing cone (angle). Overall, closer is still brighter, but such offsetting issues do tend to limit the importance of placement, in terms of brightness.

The bottom line, is either ceiling or shelf mounting will work fine, with only minor advantages and disadvantages.
