Guys
I do not agree that this slight keystone correction would screw the image up that much.
You would be incorrect on that assumption.
Keystone correction manipulates the image in the digital domain. Not analog. You need to stretch or compress the image. 1/4 to 1/2 the image actually. This digital stretching is VERY noticeable.
The projector is very much in the wrong position or you are off on your setup.
