The OPTOMA's GT5600 is a 1080p entertainment projector with ultra short throw provides bright, clean images. In many circumstances, its 3600 lumens of brightness will be enough to combat ambient light, and its 20,000:1 dynamic contrast ratio and 1080p native resolution will ensure that detail is visible. It has a 0.25:1 throw ratio, allowing you to position the projector 6 to 9 inches from the screen without casting shadows from people walking in front of it.
