Hey, I'm just getting into home theatre. Bought the Mordaunt Short Genie 5.1 system the other day! Pretty excited! My question is what screens should I be looking for, for the Optoma HD70. It has a rating of 1000 lumens and contrast of 4000:1 if that makes any difference. And was also what the gain means. I assume it has something to do with brightening the image but I'm not sure. Help me out!
Thanks,
Dustin
