Plenty of threads regarding gaming on certain LCD monitors (in regards to ghosting, input lag, etc).

Any things to consider for computer gaming with a FP? Would be 1080P projector.

Recommendations on projectors or links to read?

Not all projector takes 1920x1080 via VGA input. Many accept up to 1280x720. As or DVI input most projector only accepts DVI-D where as computers most ouput DVI-I. For desktop display is it fine but encountered problem with playing games using DVI-I into the projector.

I have my 360 connected to my Infocus IN76 and even though it's 'only' 720p it looks stunning and I couldn't possibly go back to playing games on anything smaller. I do have a PC connected to the projector too, but I don't really use it for gaming since I got the 360 simply because the vast majority of PC games are not ideally suited to playing on the sofa (even if you get a nice cordless USB controller).
