Just got an Epson 5020 installed last week. Screen is a Da Lite High Contrast Grey Screen.
Whenever the screne is a pure white or light colored, I can see these faint blackish.gray streaks. In this case i'm sitting off to the side, so I can only see it on that side of the screen. if I sit in the middle, then its directly in front.

Attached is a picture. Sorry for the poor highlighting...

Looking for input if this is something to be expected with an LCD projector and Grey Screen, or do I have an issue with one or the other?

Is your screen a manual pull-down? I have the manual Da-Lite Model C high-contrast matte white paired with a Panny PT-AE4000U and I do have similar issues due to it being a manual screen that is not perfectly flat. The, albeit, small "hills and valleys" do cause, what I call, shadows that are barely noticeable during still scenes, but are during horizontal pans. Especially on brightly lit ones like a pan across a desert or the sky. But like I said, I don't really notice them during still bright scenes.

Actually, I'm getting ready to get rid of my Panny for the Epson 5020UB so I'd be curious about what others will respond to your situation.

No it's a fixed screen. It is perfectly flat

So if you move the projector so it throws the image on the left half of the screen, do the lines move with the image? So are the lines projected just left of center at that point respective to where they are now on the full screen? If so, then they're being projected by the unit. Otherwise it's the screen.

You know. I Haven't tried to moving it yet. Good point. I will try that tonight

Have someone hold a piece of white computer paper in the area of the black marks and see if they show up on the paper....

Why not just use the horizontal lens shift?


moving lines = projector, stationary lines = screen
