It's got me befuddled! I have the DT-300 ceiling mounted about 9 feet back of the 92" Da-Lite B HCMW and cannot seem to get rid of the moire lines. These lines are present whether I use a Sony or Samsung player and can be seen at all resolutions from 480i/p up to 1080i. I then bought a Gray Wolf screen hoping to fix the problem and.... it did! However, since my PJ is ceiling mounted I'm now outside the cone and the brightness drops off dramatically when I sit. If my PJ was table mounted this whole situation would be moot. So, I've determined that it's the combo of the PJ and the screen and I'm wondering if there is a way to fix it. I'm in a catch 22, the Gray Wolf shows no moire but the picture is dim, The Da-Lite is bright but shows moire. Help!
