I would like to use a Stewart microperfed screen with a Sony VW10HT, however, I am concerned about moire effects. The screen will probably be 96" wide. Can I expect moire effects to be a problem with this projector/screen combination? I have read that these problems can be reduced by either defocussing the image slightly or by using a Cygnus processing lens. Can I expect either of these methods to eliminate the moire effect? My first choice would be to use defocussing. Does the amount of defocussing required to eliminate the moire effect result in a loss of detail in the projected image?
