Hi all. I'm just about to purchase some screen material for my first projector. I've decided on a fixed screen since its in a dedicated AV room, so I just need the screen material rather than a retractable screen. And screening will be done in black out condition with low ambient light. I am however a little confused by the option laid down in front of me. Here's how it goes at the moment: I'm deliberating between 2 screen material at the moment, both are from DRH. The two screen materials are the High Gain and the High Power, with 1.8 and 3.2 gain respectively. I was considering the brute force approach by just buying the High Power stuff with the 3.2gain. What advantages and disadvantages are there with such a high gain screen? Or would the 1.8gain be better? Can somebody please put me out of my misery and recommend one of these materials to me. My Projector is an LCD model NEC VT45: 700 ANSI lumens in eco2 mode though can do 1000 ANSI on full but I won't be using it with this as lamp life is reduced to 1000hrs. Contrast Ratio is 300:1 Thanks for any input.
