MY PROJECTOR IS 4M FROM THE SCREEN. THE PICTURE IS WIDER AT THE BOTTOM THAN ON THE TOP. I HAVE CHANGED THE PICTURE TO ALL SISES BUT THE PROBLEM IS THE SAME ON ALL 3 SETTINGS. THE PICTURE QUALITY IS PERFECT.
HERE ARE THE SCREEN DIMENSINS. I HAD IT CUSTOM MADE FOR MY HOME.2640MM X 1360MM. PICTURE FITS PERFECT ON BOTTOM (2640MM) BUT SLANTS INWARDS TOWARDS THE TOP OF THE SCREEN I WOULD SAY BY ABOUT 50MM ON EITHER SIDE.

Hello! Any picture imperfection in any LCD projectors is caused by light engine's damage. It could be due to constant overheating, dust accumulation, etc. In any occasion, the light engine must be replaced or repaired(if possible). If that glow is not substantial yet and you can live with that, just ignore it. It will get worse, eventually, then you will think over: to repair this projector or replace it with a new one. good luck, thanks, Alex.
the light tunnel has collapsed and needs replacing. the part is inexpensive and relatively easy to replace. if you can get the part from infocus or an authorized service center (part # 306-0095-01), remove the top (4 brass screws and 4 silver screws on the bottom, 2-3 silver screws on the back), next to the lens is the colorwheel. remove the 2 black screws on the colorwheel base, 2 black screws on the metal tunnel frame side, remove the tunnel glass. replace, and reverse the instructions to put it back together.
If this is the case check that it is installed with the lens of the Projector in the facing straight to the middle of the screen or try adjusting the bracket's swivel head to move it a bit - should do the trick !
