Review Projector Acer C205

  • PROS

    Small and portable. Can project from and charge MHL-enabled tablets and smartphones. Reasonably strong, good-quality audio.

  • CONS

    Limited to HDMI/MHL connectivity. Poor text quality. Some rainbow effect in video in our tests.

  • BOTTOM LINE

    The Acer C205 is a compact projector of modest brightness and decent audio output, designed for businesspeople who need to give presentations in small rooms.

The C205 is an LED-based DLP projector with a rated brightness of 200 lumens and native WVGA (854-by-480) resolution. Acer claims a lamp life of up to 20,000 hours in Standard mode and 30,000 hours in Eco mode, so the light source should last the lifetime of the projector.

The chassis measures 1.1 by 5.7 by 4.3 inches (HWD) and has a simple, handsome design. It’s rectangular with semicircular wings that house its two 2-watt speakers. The speaker and ventilation grilles are silver, while the rest of the projector is white. The projector itself weighs 10.7 ounces; adding the power adapter brings the total weight up to 17 ounces. The small focus wheel is out front, next to the lens.

A built-in, rechargeable 4,200mAh battery provides up to 2 hours of cable-free operation. Connectivity is limited to an HDMI port, which also supports MHL, letting you connect to an MHL-compatible smartphone or tablet to project images, as well as charge the mobile device. There’s a USB Type A port, but its only function is to let you charge a USB device, such as a smartphone. The projector also has an audio-in jack.

Testing

I tested the C205 from about 5 feet away from the screen, where it threw a 4-foot (diagonal) image. There was some degradation in image quality with the introduction of ambient light; the image looked better when I reduced it to about 36 inches (diagonal).

Data-image quality, while otherwise decent, is brought down by poor text quality. Black text on white was readable (though not sharp) at 10.5 points, while white text on black was only easily readable at 12 points or larger. You could use the C205 for presentations, but you’ll want to stick to larger type, and it’s best to use black type on a light-colored or a white background. The upside is that there’s no tinting to speak of, and colors are well-saturated, though there is some pixel jitter.

I noticed rainbow artifacts—small red-green-blue flashes—in some bright areas against dark backgrounds. This so-called rainbow effect, which is frequently seen in single-chip DLP projectors, is less of a problem with data images than with video. Even those sensitive to the effect are unlikely to be bothered by it when watching data presentations with the C205.

Video and Audio

In our testing, video was of a quality suitable for shorter clips as part of a presentation. Rainbow artifacts were more apparent in video than they were in data images in our tests, and they’d likely be distracting to those sensitive to the effect. When you’re presenting on the road, you have no way of knowing how sensitive to these artifacts your audience may be, and thus you’re best off using video sparingly with this projector.

Also, some pixelation due to the projector’s relatively modest resolution is evident in video. This can be counteracted by keeping the projected image relatively small; a 36-inch (diagonal) image is a good size both to reduce pixelation and to keep the image relatively bright.

Audio from the twin 2-watt speakers is of decent quality, and should be fine for a small room. This puts the C205 ahead of the many palmtop projectors that are barely audible unless you’re sitting very close to them.

The C205 could be thought of as a miniature version of the Acer K137 it’s smaller, and has lower brightness and resolution than that 700-lumen WXGA model. The Acer K137 has slightly more powerful (two 3-watt) speakers as well. The C205 is even more portable, and sells at barely half the price of the K137.

The AAXA P4-X Pico Projector, Editors’ Choice as a micro-projector (pico or palmtop) is dimmer than the C205. It’s rated at just 80 lumens, or 50 lumens if you’re running it from its battery. Even so, it showed surprisingly good image quality in our tests, with good text quality and decent video with a minimum of rainbow artifacts. It also has the ability to project content from a microSD card or a USB thumb drive.

That said, the AAXA P4-X’s sound is barely audible. If audio is important to your presentations (and text quality isn’t vital), and if you can connect with HDMI or MHL, the Acer C205 is worth considering.

  • Excellent warranty
  • Lowest priced 1080p 3D capable projector we’ve reviewed so far

BenQ W1070 Projector Overview

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.
