I've been projecting on a wall for some time to get a sense of good screen size relative to viewing distance, etc. In an ideal universe I'd like to go 145" diagonal. The problem I'm having with that is frankly I'm having a hell of a time finding any 1x3 hardwood in 12' lengths that is remotely straight around here. I'm tempted to just cut the width down to 10' and go with the resulting 138" diagonal but then part of me doesn't want to give up that screen real estate. I haven't looked at any specialty wood suppliers, just been looking at the box stores for now. Any thoughts on that?
OK....nuthin' like an easy solution to speed things on their way......
.......and in the size that was universally desired. I see mentioned a specific format of 16:9 and the main concern being getting your Wood.straight enough to satisfy the need..
Ergo....a Sectional Frame made from the straightest 8'ers you can hand pick. (...a usually more governable task...)
Starting off, a Constant Image Height approach that easily uses the 58" wide spandex.
The Size / Format above provides a maximized Widescreen image while still providing a over 124" diagonal 16:9
Also I'm wondering if I can use the standard 80/20 spandex at the 138" size or if the 67.5" height with added margin for the edges and stapling is too far to stretch this material? I assume if I go any larger than that I'd have to use the 120" spandex for black and white. Is that correct?
Sure you can....if you do it precisely, pulling equally in every direction.
Here is the largest I would suggest in 16:9.
Of course anything else smaller works too. A simpler done 138"er if finding some straight stock allows.
When you use the Standard sized 80/20 and stretch it out to 70", your as far as you should attempt to go.
