brightness (a) x screen size(b) = what projecter? ?????
So my problem is trying to figure out how big of a screen to get. I have room to go as large as I really want to, but the problem is how do i figure out how which projector will work for me other than just looking at the lumens? I have seen small cheap projectors that claim to light up to 200- 300 inches and others that cost several thousand dollars that have a hard time filling up 120, let alone 3d. so if anyone can give me a guide as to what to look for that would be great. Thanks in advance.
