Got to love that LED light engine.QCast Mirror lets group meetings and family get-togethers share Full HD content wirelessly from any iOS, Android, Windows, or Mac device. Visually, it appeared to be brighter than expected, and can cut through some real ambient light despite its low lumens – it’s actually better at handling ambient light than that Acer I mentioned earlier, which had over 2,000 lumens. ![]() Though close, the projector did not meet its 1,000-lumen claim. The CH100 has a high contrast ratio of 100,000:1. The differences between modes are often subtle, so it will really just come down to preference and how bright you need the image to be. The color on the CH100 is excellent, with each mode having great, albeit similar color. The result is a crystal clear picture and sharp text. Many business/education projectors are WXGA resolution, which is lower than HD at 1200 x 800 pixels, rather than 1920 x 1080 (HD). The CH100 projector features full HD resolution, which was a huge plus for me. That’s pretty much all you’ll need for your business or scholastic presentation anyway. For video and image sources, there are only two HDMI inputs and a VGA connector. We’re talking simple, straightforward, with no frills whatsoever. With only a few inputs and connectors on the rear panel, the projector is easy to use – ideal for those who just want a “plug-and-play” projector. The BenQ CH100 is a $999 portable business projector that is the embodiment of simplicity. This projector is a definite contender for those where portability, price, and picture are of great importance. The BenQ CH100 handles ambient light fairly well, but you’re likely to want to have at least some degree of control over the lighting in the room. It sits a full two feet back from where the Acer (recently reviewed) was to fill a 92-inch screen – putting it at nearly six feet back from the screen (though for business and education applications, it’s not likely that you will need to fill a screen so large). It’s a short throw projector, but has a longer throw distance than is average for show throws. The CH100 is very portable and slim, weighing in at just over five pounds. BenQ, however, offers up the CH100 in a competent attempt to cross a pocket projector with a “real” full sized one. ![]() The 1000 lumen rating is, these days, is less than half of most lamp based competitors, and more typical of the brightest pocket projectors (which are LED powered but smaller). That provides an excellent value proposition when considering that you would need to change that lamp just under four times before the LED light of the CH100’s engine will need maintenance.ssss By comparison, I reviewed a similarly-priced lamp-based crossover (business and home) projector, which could get up to 8,000 hours in Eco mode. The CH100’s light source can last 20,000 hours at full power, 30,000 in Eco mode. The lamp-free quality of this projector gives it an advantage over its lamp-based counterparts, most obvious in the rated lamp life. The BenQ CH100 is a slick, small, HD resolution, DLP portable business projector with an LED light engine, claiming 1,000 lumens.
