Re: Star Wars vector issues (6100)

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?

It's also definitely a board-related issue - I've had my SW hooked up to another 6100 and the issue showed up on both. Has anyone seen this before, and if so, where can I start to fix it?
