Just a little more advice from you all, and I think I'll have made my selection. My room specs: 16.5' x 21' x 8-12' vaulted ceiling. Imperfect light control. I can easily read even with all blinds closed during the day. Light does not shine ON the screen, there is just a lot of indirect/ambient light (the blinds "glow" their color). My desire: 120"+ screen, ability to watch during the day. My biggest questions: Will 1000 lumens be enough?! And how close will 1000 lumens approach the brightness of my 65" RPTV? Is it going to be "almost as bright", "half as bright", "nowhere near", etc? The RPTV is easily watched during the day if I close the blinds and don't watch really dark stuff like Unbreakable. The projectors I'm considering: BenQ PE8700+ InFocus 7200 Sony HS20 (for the 1400 lumens, but I'm not sure because it's LCD) Please advise. Thank you!
