    As the topic title states I'm seeing the reflection of my projector lens light bulb on my my projector screen. The projector is an Epson 5030 and my screen is A 110" Elite series screen in white. I've tried a few things such as turning down the lumens and the brightness on the projector but nothing has worked so far. It happens in all modes. Is this a screen or projector issue? Anyone else experience this and if so hod did you stop it from happening? It's irritating and really distracts from the otherwise phenomenal picture quality of this projector.

    Hmm, I have a similar setup but never that problem. Something with the lens shift maybe?

    I suffer the same with my Epson 9500 UB onto a 110" Affinity .09 gain screen. I sit 12' away from the screen and it also happens to the seats next to me. I have never found out if it happens to the seats behind me which are elevated 9" up.

    I've just grown used to it, but sometimes it rears its ugly head.

    It's called hotspotting. You probably bought a screen with too high of a reflectivity rating. What's the gain on that screen? Try a grey screen.

    I'm not sure what the gain is on the screen. Good to know I'm not alone, not so good to know that the fix probably requires me to purchase a new screen. Would I have any luck painting the material a flat light gray color or would that just destroy the screen?

    I don't know, but I'd not ruin a working screen to experiment... Good luck!

    Edit: What kind of wall do you have behind the screen? Try beaming onto that and see how it looks and if it knocks the effect down.

    The wall behind the screen is black painted dry wall. I guess I could get some light gray flat paint and paint the area where the screen goes as a test.
