Acer K11 Pocket Projector

Allan Abbott, July 7, 2011

If you make presentations to small audiences in rooms where you can turn the lights down, there is a 200-lumen DLP projector that you should consider . . . the Acer Model K11. At only 1.3 pounds with a list price of $379, the K11 is portable, inexpensive, and comes with its own carrying pouch, so road warriors will find it a good value. Along with video and computer inputs, the K11 also sports an HDMI input for connection to digital sources (e.g., DVD players) that you may have access to at your presentation. You will be surprised at what a good image you get from such a small projector, and that is a strong point for the K11 . . . it outperforms most of its competition in terms of video quality.

For less formal settings, the K11 performs well for family gatherings where viewing home movies or pictures from a recent vacation is the focus for the evening. It is compatible with personal devices like iPods and iPhones, and it has both SD and USB inputs which can display stored images from memory cards and thumb drives. This input versatility is uncommon in pocket projectors, and it virtually eliminates the need to have a computer connected to enjoy using the K11.

Advantages & Features

Image Quality: You might expect that a 200-lumen projector would not put up a memorable picture, and in high ambient light, the image is a bit weak unless it is kept to relatively small dimensions. In controlled light conditions, however, the K11 offers an image that compares favorably with more expensive projectors. Colors are balanced, and highlights and shadows are rendered well with minor adjustments to the image menu. There is no perceptible digital noise on HDMI material, and flesh tones are spot on.

Computer data has good color saturation with no readability problems at maximum keystone correction, and edge-to-edge sharpness is excellent. The native 858x600 DLP chip minimizes any screen door effect, and the K11 synced immediately with both PC and Mac inputs. There are no color variations with white backgrounds, and photos are clean and crisp.

In most office environments, if you limit the image size to 40 inches diagonal you will keep the image from washing out. At home in the evening with the room darkened, you can enjoy the K11's maximum image size of 80 inches without degrading the image, but a smaller diagonal is called for if afternoon sun is streaming in the windows.

Brightness and Uniformity: The K11 put up 170 ANSI lumens at its brightest setting, and uniformity was a very respectable 80%. No hot spots were noted although the lower right portion of the image was slightly brighter. For a small projector, this is a lot of light and is sufficient for intimate settings where smaller image sizes are acceptable.

Connections: For such a compact projector, the K11 offers a variety of inputs. A VGA connector handles computer signals or component video, and an HDMI port takes care of digital inputs. Alongside is a USB-A input for thumb drives, and near the bottom of the case is an SD card connector. Rounding out the array is a 3-segment mini-jack that handles composite video and/or audio. For your convenience, the K11 package includes a 3-segment mini plug to triple RCA connectors for composite video connection.

Computer-free Inputs: If you have consolidated photos, music, or videos onto a thumb drive or an SD card, the K11 can take them directly. Simply plug in the media and the menu for photos, music, and video appears. You can see or hear what you have recorded sequentially or randomly, and presentation modes for both are selectable. Connecting an iPod or iPhone is easy for viewing stills or video, and several recoding formats are supported.

Auto Source Search: When you have multiple sources connected, it can be cumbersome to cycle through those inputs to select the one you want. The K11 can be set to search for sources automatically and save you that inconvenience. If you prefer, the automatic search can be disabled.

Maintenance: Since the K11 is a DLP-based projector, there is no air filter so maintenance is a breeze. An occasional vacuuming of the air inlets and exhausts will suffice. The other good news is that illumination is provided by LEDs with a projected life of 30,000 hours, so lamp replacement is not a factor.

Image Size and Position: For an 80" image, the center of the lens is 6.5" below the bottom of the image. This is a good offset for tabletop mounting, but you may need to make further adjustments by raising the front of the projector. The projector can be elevated by extending its front elevator foot, but horizontal leveling has to be accomplished by shimming one of the rear feet. If the image keystones, there is ±40° of electronic keystone correction available, either manual or automatic.

On-Screen Menus: Menus are easy to navigate, and the menu controls are pretty intuitive. On first power-up, you get to make some basic choices, and the standard menus kick in thereafter. You can activate menus from either the projector-mounted buttons or the remote control, but using the remote ensures that you will not accidently move the projector while making a menu selection.

Remote Control: Many projectors of this class have no remote control at all . . . they rely on you pushing projector buttons which can jostle the image. The K11's remote is credit-card size and well laid out, but beware of it inadvertently wandering away in someone's pocket.

Quick Start: One of the virtues of LED illumination is that there is no need for lamp warm-up. Within ten seconds after you hit the power button, you are ready to begin your presentation.

Do you know if Acer K 11 support 5.1 Dolby Surround Sound? I know there is no audio output but someone from Monoprice told me that if my projector doesn't support 5.1, then it might cause some issues. I am using it now with my Apple TV and I am pretty sure I hear surround sound, but I am wondering if it is officially supported.

My former post here was prescient. Just a week or so ago, after less than 2500 hours of use over 3years (I have 3 other projectors) a note popped up on the screen indicating that the 'useful life' for my Acer k11 projector in standard mode was coming to an end and recommending replacement of the lamp. I had thought to notice that the projector was getting dimmer. So flogging LED longevity--supposedly 30,000 hrs-- might just be a sales pitch if you can't run in normal mode for more than 2000 hrs.

Hi:

I have the AcerK11 and love it for presentations. I would like a different remote that is easier to use and has a laser pointer. Any suggestions? Thanks.

I loved my little Acer K11 - until it stopped working.

It was small, versatile, had a great picture.

I am a consulting engineer, and I used it some for small group meetings, so that everyone present could be looking at the same file (no matter which program we were in) without having to crowd around a computer monitor.

I also used it for movie night at home with family friends.

It worked great for both applications.

But somewhere along the line, it became unable to read a signal. I have spend multiple hours with online technical support (who confirmed it was still under warranty, since I just bought it last winter), and was even instructed to send it in for repair at one point - which I did, exactly as instructed.

It still does not work. It can't read a signal from my laptop, my son's laptop, my thumbdrive, my external DVD drive, etc.

I got my $400 worth of use out of it - but I would not recommend it to someone else.

I wonder if Projector Central can investigate the claims of LED longvity. We all know that lamps deteriorate with each hour of use. It has seemed to me that some of my conventional lamps have, over time, gone from vibrant color to sepia--almost approaching black and white! But what does it really mean when a manufacturer claims 20 or 30 thousand hours for an led source? The best technical benchmarks consider an led array is finished when it sinks to 50% of output. Is this the formula for longevity that the projector manufacturers are using or what? As it is, the figures may not mean anything more than that the led array won't burn out.

I bought an HTC EVO 4G Smart phone because I saw the Best Buy/Sprint commercial that was using the EVO as the source for a video/presentation. As a road warrior I’m always looking for ways to minimize my weight burden. Since I present many power point-type pitches, this seemed to be a great replacement for my laptop, and much more versatile. Then I began my quest to find the mini projector such as used in the commercial. Best Buy is less than clueless [regardless of the store location - and it’s their commercial!]. Acer cannot provide any answers [very poor customer help], and Sprint cannot explain why the ACER K11 won’t work. Unfortunately, your reviews don’t really address the problem either. I found an ACER K11 at a Fry’s Electronics in Las Vegas, and thoroughly tested it using my HTC EVO 4G… never could get it to work regardless of all of the variations tried. The Salesman’s Motorola iPhone worked flawlessly! My best educated guess is that it simply is NOT Android compatible. However, I may be able to use the USB/SD option – I need to test this. If anyone has success displaying MS Office products, please let me know. Oh, and if you know what mini projector was used in the commercial, I’d really like to know.

Hi folks -

Thanks so much for all the great info on your site. I'm new to projector-world, and am considering one for casual use on family movie nights. Trying to figure out the connection issue for audio. Would I just hook up audio cables to a tuner through the DVD player that is connected to the projector? Remedial question -- sorry!

I like the ease and bulb of this model. Not to mention the price point. Not looking to spend a lot for this casual purpose...would you recommend other entry level models that would fit my needs? Would love a quiet unit as it would be near us as it projects...

Comparison question - is there a way to measure the image quality of LED bulb vs others?

Thanks so much!

-DJ

Lois, we have reviewed the Acer K11, but not the Acer X116P. We and our readers have given the K11 a 4.5 out of 5.0 rating. Since we have not reviewed the X116P, we cannot advise you on which might be better suited to your needs. You can compare these two projectors by going to Search by Feature, select Acer, and click the check box of each model. The link to Compare will appear in the upper right hand of the page.

I need some advice. As a classroom teacher, who is trying to buy a projector with her own money, I am torn between the K11 and and the Acer X1161P 3D-DLP Projector . Both have their positives and their drawbacks. I do not typically shut all lights in my medium-sized classroom, which holds 25 students. I was wondering if you could help me make up my mind. (Cost is too close to be a factor.) I generally show video clips and PowerPoint-type presentations, in addition to presentations I create myself.

I find your articles and website to be very comprehensive and helpful.
