Permanent marks on monitor

Will82 · 23 Jan 2015 at 14:10

I cleaned my monitor today with some screen wipes but noticed two small horizontal lines left behind that won't come off.

They're most noticeable when the screen is white and the best way to describe them would be, when you get water on screen, you see a multicoloured mark that disappears when wiped dry. Well, these two lines look like that, about a pixel in width, but they won't go away. They don't look like dead pixels to me as I've seen before - they look like they're behind the screen, which doesn't make much sense because they're quite far from the corners.

I tried to take a picture on my phone but couldn't get a clear view of them. Anyone have any ideas? The monitor's a 1080, 21" AOC model.

Scuffs?

I don't think they're scuffs or scratches because you can't see the marks at all when the monitor is turned off.

Try to feel it with your fingernail or something, by keeping the fingernail parallel to the mark and gently moving it perpendicularly (across), to see if it catches on them or if it's super smooth.

Tried that and it's super smooth. Could it be malfunctioning pixels or something? I know what dead ones look like and these marks aren't nearly as clear as that.

I actually managed to take a picture with my phone but weirdly the marks didn't show in the photo, even when zoomed in fully. I've tried resetting the monitor but that didn't work either.

It's frustrating because I can't find anyone online who's had the same issue. It doesn't affect gaming but it's just one of those irritating things that draws my attention whilst browsing the web and stuff. I guess I'm stuck with it for now.

put your hot breath onto the marks and wipe off asap,should shift it

A few years ago i had a similair issue on a viewsonic vx2025 monitor, a line of white pixels about 6" long in the bottom corner. RMA'd it as it was a fault with the panel and not surface marks.

can press gently/or massage the marks aswell see if that helps,but please don't press hard just enough to see the liquid crystal distort slightly

Tried hot breath and massage but to no avail. I looked a bit more closely at the marks and they both curve slightly at one end. One from the top, one from the bottom, both multicoloured when viewed on a white background.

if its a CRT they might be normal, if its tft it doesnt sound good.
