Hello. I am having difficulties finding out where I will eventually put my projector. My room seems very difficult for a projector setup. I have a vaulted ceiling and a fan coming down from the ceiling. If I were to mount the projector on my side wall and have it not completely centered with the screen, how much picture quality would I lose? Someone explained to me that you can do this with a keystone correction(?) and it will work but will lose some quality. If I did this method the projector would be about three or four feet left of center on a 106" 16:9 screen. Is this to far off center or would I be alright and not lose to much quality? Thanks for all the help.
