Bit puzzled about this. You can buy nice screens full of glass beads which seem to be what you want if you have a massive CRT projector. But, you are told not to get something like this, of pretty much any screen with any gain if you have a LCD projector as you will get hot spots caused by the light reflecting back into your eyes. So, why don't you have this problem with a CRT? Can you actually have ANY gain screen with a LCD projector to make the image shine a bit more than a matt surface without any problems, or is it just a no no.
