Our classroom video projector's fonts look pixelly and the background seems slightly marbled, any clue ???

Question

Our classrom projector is about 10 years old. We just replaced the bulb (as we have over the years) now the fonts look pixelly and there seems to be a faint marbley like background with the image. The image looks clean but there is this slight marble look to it. Any suggestions for us ? Is it the projectors age ? We are running it at 1024X768. We tried adjusting the APA as well as the contrast, brightness, etc...

Answer 1

it could be the screen.

are images left in one place for extended amounts of time?
