The projector has multiple modes, including one specifically for gaming. In all of the modes, the picture is super bright and crisp (thanks to Darbee enhancement features). With 16ms of latency, this isn't as fast as a gaming monitor but definitely one of the fastest projectors/tv setups for gaming. It adjusts automatically. Even if you mess with the other settings in the menu screen, it takes a maximum of 20 minutes.
The image quality of BenQ has amazing colors thanks to the RGB color wheel. It also has great sharpness and clarity. The fan is not terribly loud. Remote functions well and the unit is responsive to it. Easily mounts to ceiling with a bracket (purchased separately). The sound from the built-in speaker is average for a projector. As long as you don't care much about how good it sounds, it gets plenty loud enough. Great for home theater and gaming with no noticeable lag.
