Is my gpu faulty or is it the monitor?

Hey guys, long time ocuk customer here, basically I run 2 gtx 760's in sli, both of which have 4GB Vram, one of them does not work correctly now so I am in process of RMA for it, now the second card is playing up.

Basically I am seeing green pixels in games and on website images, if I run my monitor to 60hz they become less apparent, if I run the monitor at 120hz they are really bad, the pixels move with the image and sometimes flicker, I have tried different drivers and dvi cables but same problem.

I really hope it is not a problem with the monitor as it will cost a lot to ship back, does anybody know if its likely to be the gpu or monitor that's causing the issue? I don't have a spare card so I can't see what is actually causing the problem.

I just want to know if its worth RMA this second card because I know there is a fee if EVGA find there is not a problem.

The graphics card is not overheating either, these green pixels appear straight away on games.

Oh and the green pixels only appear on the right hand of the screen

If you have onboard graphics on your motherboard give that a test to see if you see the same problem. Looks like graphics card (VRAM) to me that problem or bad drivers.

VRAM !! RMA time

Hmmm I tried a spare 1080p 24inch monitor I have and I don't see the green pixels at all, but I just noticed if I set the video settings of a game to windowed full screen, the green pixels go completely, so they only show up when in full screen mode

NVM some are still there it just reduces them a bit, must be a faulty monitor..

So on a different monitor you don't get the problem at all?

Check a different cable. It's common for a faulty cable/connection to cause graphical issues.

If your getting it on 2 different monitors then its your cards, what psu have you got in?

Sorry I meant it works fine on my 1080p 24inch benq led monitor, but if I downclock the monitor to 50hz, the green pixels go away completely, so i don't know if it means it is still a issue with the monitor or the actual gpu

Maybe it stops when you down clock the monitor because its not getting as hot with being locked to 50fps?
