I just want to bounce this off of you guys, advice is welcome because I need it. In 2 weeks I will be moving and setting up the new HT room. I have done all the video and audio pre-wiring already and will be setting the projector (Sony 11HT) 12.5ft away from the front wall. The challenge here is the ceiling which is 12' high (144"). The screen I will be using is a Stewart Firehawk 92" which is 45" x 80" without the 3" border accounted for, or 51" x 86" with the border. My dilemma here is how high to mount the screen from the floor, how long of an extension pole to use for the projector mount, and how much keystoning correction I should use. (My initial thought was to mount the screen 40" off the ground)... The two exteremes are as follows.... 1- Use no keystone correction but resort to an extension pole of 56-60" (very long pole/mount). 2- Use maximum keystone correction and end up with a much shorter mount/pole for the projector. Of course, I could also play around with the third variable which is the screen height. What are your thoughts on this... Thanks in advance.
