Ever since i bought my new monitor (Acer Preditor GN246HL) I have been getting weird green pixels all over half my screen, i was wondering if this could be my graphics card causing the problem. Should I upgrade to an RX 570? The green pixels only show up in dark areas of the screen.

i was wondering if this could be my graphics card causing the problem.

To determine this, use a different monitor on the same output, or connect the Predator to another system. Whichever still causes the green pixelation is the one that has a fault.

You say 'Your new monitor'. As Platypus has said, connect it to a different computer to see if you are still getting the green pixcels.


If you are and if the monitor is still new enough to be inside warranty contact your supplier to make a claim.
