Highly portable and cost effective, the C20 is a really good effort from Acer, and the ability to project a decent 66in display from such a small device is especially impressive. While it will most likely be used for entertainment, business users who carry out presentations at client offices on a regular basis should also give it a look.
Decent picture quality; good connectivity options; small and portable; reasonable price
Not the brightest picture; battery life could be better; gets warm after prolonged use
DLP projector, 2000:1 contrast, 20 ANSI lumens WVGA (854 x 480 native) widescreen, 20,000 hours LED life, mini-HDMI input, component video/RGB input (on supplied cable), composite video/audio input, mini-USB, Micro SD slot, 0.5 Watt mono speaker, 166g
The Acer C20 Pico projector might be one of the smallest and cheapest projectors on the market, but it's capable of impressive picture quality.
Measuring just 118 x 60.8 x 18.6mm, the C20 is only slightly larger than the iPhone 4. It's also extremely portable at 168g, which will appeal to travelling business users. A leather carry case is provided.
It took only five minutes to unpack the device and project a 66in video onto our wall from the maximum recommended distance of 3.2 metres; 25cm is the closest the C20 can manage, at which it will project a 5in display.
The C20 is delightfully easy to set up and use. Simply plug in a video source and push the search button to find the video signal.
The brightness of 20 ANSI lumens means that lights need to be turned off and curtains closed to ensure that images are at their brightest. There is an Eco mode which dims the pictures, but we found that the picture became a little too dark.
The 2000:1 contrast ratio is impressive for such a small device and, although not capable of HD, the 16:9 widescreen resolution of 854 x 480 worked well.
Images can be projected onto any surface, but a clear white background is best. The ability to screw the projector onto a tripod is also a bonus, and allowed us to accurately project an image at an angle during testing.
The projector uses a DLP chip in conjunction with an RGB LED bulb, which allows it to provide good picture quality. When we connected the projector to a laptop, the resolution on the notebook was automatically changed to 800 x 600, which made it a little challenging to navigate using the touch pad. However, we were able to remedy this by reverting to a more comfortable 1,024 x 768 resoluti on.
Another big selling point is connectivity. A mini-HDMI port allows the C20 to be connected to a variety of video sources, and it can also accept content from USB sticks and memory cards thanks to the mini-USB and Micro SD slots.
