New screen woes: noise on right side of screen
So I got this new screen... well, newish: it's an Acer XB270HU that was used to demo the product at a shop. Unfortunately it's currently unusable: the right side of the screen has lots of pixels randomly lighting up, and when there's an image, it looks like the pic below. This also happens when the screen isn't hooked up to a source. Obviously I'm going to bring it back if the problem persists, but I thought I'd ask the experts here in case there's a simple fix. Any ideas or tips, or is it clear the screen is a no-hoper?
