A screen capture utility such as SnagIt would work much better, if that's feasible.
Thanks, Peter ... but that wouldn't give you an image of the screen, just a image file that reconstructs the data sent to the screen.
This is a prototype display using new MEMs technology that is not yet in production - pretty cool stuff, actually.
For what they are trying to do, they need to actually image the physical pixels.
There is a 16mp industrial camera that they are now looking at ... my basic understanding of sampling theory tells me that this should probably do the trick, but I'm no expert.
