I have an Infocus LP350, and despite the problems (rainbow, light-leek/halo), that everyone already knows about that I knew about before buying it, it provides an excellent picture. When in DVI mode from my HTPC, it's picture is hard to match. But recently is has caused me so many headaches. I know for a fact, through many hours of testing, that it is fully compatible with my video card(s), but nevertheless, it likes to, about once every 50-60 seconds or so, do its "Perfecting the Image... Please Wait", which is an annoying blue screen that is displayed while the projector either syncs with a different source or syncs with a source for the first time. This is accompanied by moderate and somewhat random fluctuations in bulb brightness, which are clearly visible on white/lighter colored images. This appears to not be isolated to DVI/VGA usage, as the fluctuations are visible on the Infocus blue test screen itself, without a source to display. I have thought of the "common" problems (power fluctuations, line interference, heat issues) but I can't seem to get around this. Anyone have any ideas?
