I have been reading on this forum for ever and seem to run across the same questions in EVERY thread so may I suggest we make an attempt to eliminate further "What screen screen size, gain, etc. should I get?" threads by informing readers on the decisions we have made, and if we feel we made the correct choices....
1) What projector are you using? JVC RS40
2) What is your throw distance? 12'
3) What is your seating distance? 8 1/2'
4) What screen: size brand, aspect ratio, and gain? Currently Undecided
5) If you were buying a new screen would you go bigger, smaller, or same size? Not sure yet...
