Question Color banding on displayport not on HDMI

[Jeff_120]

I just bought a Gigabyte AD27QD, tried it on DP but all my photos had color banding specially the blues, no problems at all with HDMI...
I have an RTX 2080 and Win 10
Any fix?

Ok I tried another DP on my rtx 2080 and it hasn't color banding!
Dunno if it was a bad hardware DP port on the GPU itself or a bad configuration in Windows though I made a clean install of the geforce driver
