BOTTOM LINE

The Epson PowerLite 1985WU WUXGA Wireless 3LCD Multimedia Projector offers excellent image quality, high resolution, and both Miracast and WiDi for wireless connections.

BY M. DAVID STONE

With its 4,800-lumen rating, the Epson PowerLite 1985WU WXGA Wireless 3LCD Projector stands ready to deliver an image that’s both big enough for a large room and bright enough to stand up to ambient light. Add in its WUXGA (1,920 by 1,200) resolution and support for both Miracast and WiDi for easy wireless connections, and it’s of obvious interest if you need a high-resolution projector for a spacious venue and expect to have a variety of presenters who need to connect with assorted laptops, phones, and tablets.

Significantly, the 1985WU Best Price at Amazon is the same list price as the Epson PowerLite 1975W WXGA Wireless 3LCD Multimedia Projector Best Price at Amazon, which is our Editors’ Choice WXGA data projector for a midsize to large room. Aside from resolution and a minor difference in brightness, both offer essentially the same features, so you can choose between them based strictly on the best resolution for your needs.

Both models, for example, will let you show images from two different sources at once on a split screen. They also both support Epson’s control software running on a PC to let you manage up to 50 image sources and show up to four of them on onscreen at once. However, the 1985WU will let you take better advantage of split screens should you need them, thanks to its higher resolution.

One particularly important feature both models share is that they use three-chip LCD engines. That guarantees that they can’t show the rainbow artifacts (flashes of red, green, and blue) that are a potential problem with single-chip DLP projectors. The design also ensures that color brightness is the same as white brightness, which means you don’t have to worry about a difference between the two affecting color quality or the brightness of color images. (For more on color brightness, see Color Brightness: What It Is, Why It Matters.)

The potential disadvantage for the 1985WU is that, as with most LCD data projectors, it doesn’t offer any 3D support, which you’ll find in the vast majority of DLP models. This isn’t an issue for most applications. But if you need 3D, you obviously have to look for a projector that offers it.

Setup
The 1985WU measures 4.9 by 14.8 by 11.4 inches (HWD) and weighs 10 pounds 3 ounces, making it best suited for permanent installation or for room-to-room portability on a cart. The one unusual touch for setup is that if you want to take advantage of a standard Wi-Fi connection—as opposed to Miracast or WiDi, which are both built in—you have to insert a supplied Wi-Fi dongle into a USB Type A connector hidden behind a side panel. Beyond that, setup is standard, with a manual focus and a 1.6x manual zoom.

Using the Society of Motion Picture and Television Engineers (SMPTE) recommendations for theater-dark lighting and a 1.0-gain screen, the 1985WU’s 4,800-lumen rating would make it bright enough for roughly a 265- to 355-inch image (measured diagonally) at the projectors default 16:10 aspect ratio. Even in moderate ambient light, it’s bright enough for a 175- to 195-inch (diagonal) image. You can also lower the projector brightness for smaller screen sizes, by switching it to Eco mode, using one of the lower-brightness predefined modes, or both.

The back panel offers a fairly typical set of connectors, including two HDMI ports, with one that supports Mobile High-Definition Link (MHL), a composite video port, and two VGA ports. Other image inputs include a USB Type B port for direct USB display and for controlling the computer mouse from the projector’s remote, a LAN port for both controlling the projector and sending images and audio over a network, and a USB Type A port to let you read files directly from a USB memory key, connect a document camera, or update the projector’s firmware.

There are almost as many choices for wireless connections as there are physical ports. The easiest to use is Miracast or WiDi, assuming the device you want to connect supports one or the other. If not, and the projector is connected to a network using either the LAN port or Wi-Fi, you can use the Epson iProjection app to connect through an access point on the network. You can also set the projector to allow a direct connection by Wi-Fi instead, and connect directly to it with the app instead of going through an access point.

Image Quality and Audio
Image quality is one of the 1985WU’s strongest points. The projector breezed through our standard suite of DisplayMate tests with impressively good color balance and color quality, and no issues worth mention. It also maintained detail suitable for its high resolution. Black text on white, for example, is crisp and highly readable at sizes as small as 6.8 points, and white text on black highly readable at 9 points.

Video quality is nearly a match for some low-cost home theater projectors. That makes the 1985WU far better than most data projectors for video, and easily usable for long video sessions, or even for watching a full-length movie.

Also very much on the plus side is the audio system, with the 16-watt mono speaker delivering good sound quality at a volume suitable for a midsize room. If you need higher volume, stereo, or still better audio quality, you can easily plug an external sound system into the audio-out port.

BenQ W1070 Home Theater Projector Review

BENQ W1070:  Wow!  3D capable, 1080p, exceptional brightness and the promise of really good color!  Sounds like an expensive projector.  Not true.

Allow me to introduce you to BenQ’s W1070.

BenQ W1070 Highlights

  • 2000 lumens bright – suitable for family/living/bonus rooms
  • 3D Capable
  • Higher contrast for better blacks, than most low cost projectors
  • 10 watts of Audio, audio output
  • Full color management controls, ISF certified
  • Minimal lag times for great gaming
  • Remote control
  • Smart-Eco for energy efficiency (see more below)
  • Very long lamp life (for low cost of operation)
  • New lighter 3D glasses from BenQ (not included)
  • Excellent warranty
  • Lowest priced 1080p 3D capable projector we’ve reviewed so far

The BenQ W1070 is a Light Canon of a projector! Mind you, there’s no official determination of how bright a projector has to be to be one, but I’ve referred, in the past to a number of projectors as light canons, that even in their brighest modes, can’t match this 2000 lumen rated BenQ W1070 even after its calibrated.

This is a single chip DLP projector. A small one. Although you can find a few smaller home entertainment projectors that are smaller (all DLP) I can’t think of a single 1080p LCD projector that isn’t dramatically larger.

Physically the W1070 looks pretty cool, or at least cute! But, it’s the picture that we really care about.

I have yet to see an official price. The projector is just starting to arrive in the US, even though it’s been available in Europe and elsewhere for months. In the EU it’s supposed to be $749 last I checked. It turns out that the official US price is $1099. It’s the lowest cost 1080p 3D capable projector yet to grace our theaters.

The projector is just starting to ship in the US as this is published. 3D Glasses are not included. The official price for the glasses is $79. Even that is a little less than most others.

Contrast, it should be noted, is also a lot higher than most of the competiton, which should indicate respectable black levels for the price. Just don’t expect too much in that regard, as projectors with great black levels are typically at least $2500. It’s less of an issue in a typical family room type environment.

Let’s take a quick look at some bullet point highlight, some specs and then we can get into the meat of this projector review!


BenQ W1070 3D

3D looks very good. Before I get going on the BenQ’s 3D I’ve got an interesting story (cautionary tale) before I go further. I’ve been having problems with one of my long cables of late, ordered in someone’s “top of the line” cables (off of Amazon – I was in a real hurry), and when I put on John Carter in 3D last evening, all kinds of crosstalk and judder. Switched back to that truly (but 5 year old), top of the line cable – an Ultralink, and all that garbage went away. I confirmed that the problems also were there when I switched to an expensive JVC projector. BTW the issue was with Blu-ray 3D, side-by-side off of HDTV didn’t seem to suffer.

If you think you are the type who will upgrade in a couple of years (maybe to a 4K projector when they become affordable), that’s a killer reason for buying really good cables.

Back to the 3D performance. With a proper cable, crosstalk is a non-factor. I found watching 3D to be rather enjoyable and relatively bright. Color was pretty good (in 3D), I don’t expect color as good as 2D, and we have never tried to calibrate 3D.  The excellent brightness allowed me to put on some widescreen movies and fill my 124″ diagonal.  Not bad, watchably bright.  At 100″ diagonal there’s plenty of lumens for 3D.  After all, consider that 400 lumens is more than enough (with proper lack of ambient light) to watch a 100″ screen.  With over 1700 lumens calibrated, that’s more than 4 times as much.  3D no longer costs 75% of brightness even if it does cost viewers a good bit more than half the brightness.  Translated, this W1070 can do a great job in 3D on an average sized screen.

I was very pleased with HDTV 3D.  Everything from a Penn State football game, and some little league baseball I recorded in 3D, to a National Parks tour of Arches, looked really good.

Color remained good even in 3D.  Of course we never attempt to calibrate 3D, so I’m sure it could be improved.  If we find a 3D calibration disc, at some point I’ll have Mike calibrate some 3D modes on future projectors.

Overall, very good 3D, lots of brightness, and an almost total lack of rainbow effect  (for me) make this W1070 the best lower cost DLP projector for 3D that I’ve played with.

In other words:  I really like it!

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.


Acer K335 Color & Picture Quality

Two different video sources were used to evaluate the color and picture quality of the Acer K335.  To evaluate the projector’s performance for displaying business presentations and documents, I used my laptop PC connected via HDMI to the K335.  For evaluating the projector’s performance for displaying video I used a Blu-ray Disc player connected to the Acer K335 via HDMI.


Acer K335 Projector – Readability

For the initial tests the input from the laptop PC was set to the Acer K335’s native resolution (i.e., 1280 x 800).  This is expected to result in the best case sharpness for displaying text for business presentations since the projector does not need to apply any video processing to scale the image to the projector’s display resolution.  With this type of input the K335 provided a nicely sharp image and even the very small 8-point type being fully legible.

The K335 offers an assortment of projection modes and I felt for business presentations the “Standard” mode offered a reasonable trade-off between the somewhat conflicting goals of desiring the maximum light output and also desiring accurate colors.  Unfortunately, in “Bright” mode (which was by far the brightest mode), colors were significantly worse than they were in “Standard” mode.

The photos taken from the screen show the K335’s relative good performance for displaying text.  The first photo is a full screen image while the second, third and forth photos below are close-ups showing the projector’s ability to display the smaller text fonts.  I would note there was some color fringing visible when viewed up close and this is due to modest amount of chromatic aberration being introduced by the projector’s lens.  This amounted to a maximum of about a half pixed offset between the green and red color components.
