Hey Andy,
Thanks for the responses and the suggestion. I'll try it out tonight and
respond with pics.

The ylin and xlin will expand the outer couple of inches all around the edge,
but looking at your image, you need to make x and y size smaller before
adjusting the linearity, or you might not think anything is happening.

Can you take a photo of your screen with the ylin pot adjusted all the way in
one direction, then another the other way?
