MSI 3080 Gaming X Trio: Flickering on top of screen using DP

[Strigoil]

Got the card today, having issues with flickering at the top of any of my 3 monitors connected to any of the cards port via DP,  works perfectly fine through HDMI. shown in the video.

Specs:

Motherboard Gigabyte GA-Z170x-Gaming 7

CPU: i7-6700k
PSU: Corsair HX850i

RAM: G.Skill RipjawsV DDR4-2800 C15 QC - 32GB

Monitors: 3x Benq GW2765HT

The system needs an upgrade to not bottleneck the card, I know..I have all the parts needed just waiting for the new Ryzen CPUs to drop.

 

What I have tried so far is fresh driver installs several times, reseating the GPU / power cables, plugged the computer to the wallsocket instead of the surge protector to rule out an overload there.

It happens on all 3 monitors, regardless of what DP cable or DP socket I use on the card, if I run all 3 or just 1. it also happens in the BIOS so that makes me very suspicious I have a lemon on my hands.,

What is odd is when I use my display port to HDMI adapter and plug it into a DP socket on my card and them the HDMI to the monitor, the issue does not happen, but the adapter is an oldie so only runs at 1080p, changing resolution on the screens when running full DP to 1080p does not help.

 

I'm not daisy chaining my PSU power either, 3 seperate PCI-E power cables.

 

I see some people have had flickering/black screen issues who have fixed it by turning G-sync/Freesync off but my screens don't support it so its a non issue.

My final resort tomorrow might be seeing if a friend will allow me to put the card into his computer and see if the issue happens for him as well.

 

Anyone have any ideas for something I might not have tried?
