New screen woes: noise on right side of screen

Thirith

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?

Here's the pic:

That could be a software issue, but pretty unlikely when it's a brand new screen you just got.

Well, it's not brand new: it was being demoed at the shop, though they said they... reset? re-somethinged it. It shouldn't be a software thing, since it happened even when the screen wasn't hooked up to anything, unless you mean the screen's firmware rather than a Windows/driver issue.

Panels bad

Take it back, that looks like a damaged panel.

Yeah, I figured it was something like that. :-/ Chances are they'll just give me back the money, since it's a (slightly) used monitor, although I'm hoping (somewhat unreasonably) that they'll recognise me for the loyal customer I've been over the years and will give me a new monitor of the same make. Together with a wingèd pig that carries me wherever I want to go.

Way back when I worked at Best Buy's GS desk, I learned (from working with customers who did this very thing) to never buy the display model. Because people seem to have never learned to see with their eyes and not with their hands, non-defective units were the rare exception rather than the rule. Looks like you got hit by that one :sad:

:-/ Yeah, right now I'm thinking the most likely outcome is that they pay me back for the borked screen and I'll pay some more instead to get a new, functional Acer XB271HU.

Update: since they're reimbursing me for the screen that doesn't work, I've now gone for the Acer XB271HU instead. So far I'm very happy - definitely a step up from my previous, 1080p/60Hz display!
