I've been going back and forth for a while on what to do with my media room and I've finally made the decision to go with a PJ and screen. As I'm on a relatively tight budget, I ordered the Optoma HD20. I also went ahead and ordered the EliteScreen ezFrame 100" 16:9 (CineWhite); however, the more I've read, the more I've become concerned that the 100" screen might prove too big for my room, due primarily to the low ceilings in the room in question. (FYI, the room is plenty long/wide enough to accommodate a 100" screen -- it's really just the vertical limitation of the low ceiling that gives me concern).
My ceilings are 7'4" (88 inches) high. My understanding from what I've seen on the projector calculator and other sources is that the screen will need to be mounted such that the top of the screen is at least 13" from the ceiling. This is to account for the roughly 8" offset I need below the center line of my Optoma HD20, and the roughly 5" the PJ will hang from the ceiling with the Peerless PRG mount (which I understand to be the best option for mounting the PJ as close to the ceiling as possible).
The specs for the 100" screen I ordered indicate that the screen (actual viewing portion -- not frame) measures 48.8" vertically. Accounting for the 13" I need between the screen and the ceiling, the highest point I could mount the screen would place the bottom only 26 or so inches above the floor. There seems to be a consensus that most screens should be 36" off the floor or, at the very least, 30".
So I guess I have three questions:
(1) Is the 30" above the floor pretty much a cardinal rule or is there some wiggle room here?
(2) Am I missing some way to get away with mounting the screen higher than the 13" clearance from the ceiling (e.g., is there a mount that will get the Optoma closer to the ceiling)?
(3) Based on the above, would you return the 100" screen for a 92"?
I've searched and read the forums extensively over the past 18 months or so -- which has taught me a ton, and for which I'm very grateful -- but am just confused about what my best option is here. Any help would be greatly appreciated.
