Question Can I use only part of display?

[ivankhuri]

I have a broken Samsung 1080p display where only a quarter of the screen is fully functional.

My question is, does anyone know how I can still use the display (as a second monitor) but limit the screen area to the functional part? The tricky part here is that the functional part is the top-left corner, so simply scaling the resolution to the center won't do it.

My OS is Windows 10, thanks in advance.

try cru (custom resolution utility)
u can try lowering active resolution there
if it wont work, here some basics

btw first pixel starts from top left forner, so u should be able to work with that

I downloaded CRU and tinkered a little with it, but still can't seem to figure out what to do! Pretend I'm an idiot, which of these do I need to edit to get a smaller corner resolution:

doubleclick on 1920x1080 under detailed resolution

I've been trying for hours... How do I set the front porch margins? All I'm getting is a weird full screen display...
