I own the Infocus SP 4805 and I just got HD finally, however whenever a really bright scene that contains a high level of contrast comes on the screen, or if there is rapid flickering in the movie, tv show or music video i'm watching, the projector will lose contact and it takes the projector a second or two to lock on again. Again, this only happens with really bright scenes or flickering images, usually with a bright flash accompying them like you'd see during a flashback scene for example. Why does it keep doing this and, more importantly, how do I get it to stop? It's quite irritating. I have the projector connected to my cable box with a good set of componant cables, just FYI.
