First off I'll admit I haven't tried it with my projector. But, supposedly, if you get the "large" light bar it will work (better) with projectors. I bought the "large" bar hoping that it would help my scenario. Unfortunately, I find that I have to be back too far for the particular way I want to use the light gun (on an LCD in portrait mode) that makes it unusable. So, it might be a case where you need to test out your particular scenario and see if it works.
