My planned screen is 16:9 Format , 80 wide x 45 high with seating position at 11' (so over 1.5 x width). My understanding is that eyes should be circa 1/3 way up screen so that puts screen about 30 off the floor and top of screen at 75 (6' 3)
For projector my preference is DLP with a budget up to $2,500. My current contenders are (min/max mounting distance for 80 screen):
Infocus IN76 122/153
BenQ PE7700 108/148
Optoma HD72 125/151
Given that there is going to be some projector noise I would like if possible to include in the soffit (preference) or in a hush box.
My rear soffit will be 148 from the screen - so right on the boundary of the max throw distance for each projector! Will this cause an issue (i.e. does picture degrade at the boundaries?)
From what I understand the projector lens needs to be central to the top of the screen. My soffit will be 84 from the ground. So if incorporated into the soffit the lens would be 9 to 12 above top of screen. So that's a problem i.e. using keystone correction is not recommended - right?
So if I'm correct I will be better to mount projector under the soffit (and maybe raise screen a little) and then create a hush box under the soffit if I find noise a problem.
Thanks in advance for any guidance.
