I just picked up a 4805 and will be having it ceiling mounted, and it looks like the lens' distance from the screen should be somewhere around 12.5--12.7 feet. At first I was thinking it would be more like 13 and I picked up the Optoma Graywolf 106" screen. The more I read and calculate, I decided I had probably made a mistake and gone too big, and decided to opt for the 92" Graywolf. After all the raves I've read on AVS about these screens I was pretty sure they would work well for me. So now I have an unopened 106 in my living room and am awaiting delivery on the 92. The 106 won't be a problem to return to Best Buy. So did I do the right thing? From everything I have read and calculated, it sure seems like the 92" is the better option for the 4805 from around 12.5-13 ft. Or am I missing something and could the 4805 throw a good image onto the 106 from this distance? Obviously I wanted to go as big as possible but if 92 is the only viable option I can certainly live with that. Any opinions are greatly appreciated. Please forgive if these are silly questions...this is my first foray into front PJs.
