“Does the projector and the wall have to be a straight line or you can adjust the projector to correct the image in a wall that is not a straight line?”

• There are vertical and horizontal keystone adjustments. These adjustments can correct the image for minor misalignments but I don't believe it will correct for more than 10 to 12 inches of misalignment vertically or horizontally. I did have to use both the vertical and horizontal keystone to adjust for my ceiling mounted unit but used only small degree of the adjustment range, so the nearly foot adjustment is only a guessitmation based on my use.
