There is already
THIS KUAL extension to auto move the screen around a bit when reading/ viewing.
I just hacked together a version for the k3 that moves the screen down after pressing ALT+(aNything) and runs at/from startup
(So I can use it to see really badly broken screens and choose to move the screen at any time) I have a screen in front of me where the top 25% is totally trashed. This hack makes it practical to use.
A new screen is 30£ if you fancy that route
Have to see if one of the older extensions exporting the framebuffer over networking, that is all you need then? Just to see it? Nothing else?
