I've finally got my new projector and I'm looking to set it up permanently in the front room. However, I have a problem that I hoped someone can help me with. To have the projector 'straight on' to the wall were my screen is going to be, and at the right height, the projector can't be any higher than 4 feet off the floor. I don't want to ceiling mount the projector, as out ceilings are very high, so I was going to get a wall mount for a TV and use that. The thing is, at 4 feet it's not that high off the floor and it'll hardly peek over the back of the sofa. I know I could have it higher and use keystone correction, but doesn't that vastly degrage the image? I'm probably being a complete newbie and missing the point, but any help would be appreciated.
