The Optoma GT5600 review will present you with one of the best office-standard projectors. It has ultra-short throw and both vertical and horizontal distortion correction which makes it super-convenient even for small and not equipped rooms. With DLP technology and a 6-segment color wheel, you can enjoy every blade of grass in your picture.
As for the other Optoma GT5600 specs, I should mention support for different image formats (1920x1080, HDTV, 3D), a nice contrast ratio of 20000:1, and surprisingly low noise level of only 25 dB. It also features video interfaces such as VGA, HDMI, and VGA-out.
