Had my 7' Othello (Owl?) screen and Infocus 5700 projector installed yesterday. Very pleased. But... bright (near-white) areas of the picture clearly show the screen texture (a stippled effect), so the image appears to have a static watermark in some areas. I'm going back to Sevenoaks tomorrow to check their demo system (don't remember seeing this in-store). Is this kind of effect normal?
