hi i am not sure if i am using the right term (screen noise) but here goes. I bought an optima HD200 projector and am using it 14 feet from the wall which gives me a 100" (approx) image. a full facial image on the screen is stunning: HD without actually being HD (from older DVDs I have). but beyond that, it gets unclear, slightly blurry the further back in the background the subject matter is. if it's trees on 'planet earth' then they're not at all sharp and the screen image appears to be slightly, minutely moving, like water over stones. i tried enhancing sharpness but the compromise result was worse for me. any ideas on what this is and how to improve it?
