Monitor problems, need help. Pixel related.

post #1 of 12
Thread Starter 
So basically to put a long story short, Im experience strange behaviour with the pixels on my screen. On dark blue backgrounds some of the pixels keep flashing black and on lighter backgrounds the pixels are flashing in white small vertical lines and dots. I have made sure that it's not my system by testing it with another monitor and it works perfectly fine. So my final assumption is that it's got something to do with my monitor.

Does anyone know what is happening to it? Can it be fixed? I currently hardly notice it when gaming but I have a feeling that it could spread and become worse.

Sounds like the panel matrix is starting to give out. If this is the case it will deteriorate fast. If you have warranty left you should rma it.

Pretty sure I've had it for 3 years after this september, so I don't think its on warranty anymore. I will have to check. This is a bummer if there is no way of fixing this.

Well I have checked the receipt and its still under warranty until late september this year. I have everything that came with it except the original boxing, do you think they'd exchange it if I sent it with my own boxing?

Does it do this? If yes, has it always done this?

TN LCDs tend to have dithering. Not sure if that is what you are describing though.

Yes it does that, I can't say how long its lasted for as I only noticed it today when I changed my desktop picture. Then I loaded up other programs and kept looking at where I found it on the desktop and it does it in games aswell but hardly noticeable. I'm pretty sure it didn't do it before though. Like I have explained before though when I launch a windowed program I have which has a dark blue background and move it around the screen, it happens in the blue background wherever it is positioned on my screen. But yes what you linked is almost identical to it. On the lighter backgrounds it tends to be white flickers and darker seems to be black.

If you are running your monitor @ 60Hz then you should not be able to see the individual flashes of dithering. Only banding even if it is a really cheap monitor.

^that is false. Dithering can be very visible even if the monitor is set to 60hz. Some monitors do it better, some worse. The link I gave stated which things affect how visible dithering is

Well I wouldn't say it is that cheap of a monitor, at the time I paid £280 for it and that was with some discount.

So I have no clue wether to conclude this as dithering or my monitor is slowly breaking... lol

Well, I was just messing around on my desktop with that same windowed program and I pulled it over my steam friends list and noticed black dots appearing rapidly in the background. I removed it from over my steam list and they went... So it was like the colours from my steam were trying to bleed through onto the program. Anyway there are still some there on this program but I cant see any on my desktop anymore.. or notice any in my game anymore.

I literally have no clue whats going on haha...

Edit:

I take that back, It's happening again.
