1 DP port stops working

[PyTeZ]

i've got quite an odd issue regarding my GPU

 

i have an RTX 2070, running 3 monitors ( on display port )

 

a few days ago one of my monitors stopped working, i did not bother as this happened a couple times before, usually fixed by swapping cables a bit and enabling it again in control panel.

 

right now the issue: 1 PARTICULAR display port stops working when drivers are installed.

i tried DDU and using older drivers, but it seems that this particular port just shuts itselfs down as soon as drivers are being installed.

it works fine in safe mode,

it works without drivers.

it just doesn't anymore when installing drivers.

i tried 3 different DP cables,

i tried swapping the cables to different ports.

 

lets say port 2 is sleeping:

Monitor 1 on port 2 = black screen monitor 1, 2 & 3 working

monitor 2 on port 2 = black screen monitor 2, 1 & 3 working

Monitor 3 on port 2 = black screen monitor 3, 1 & 2 working

 

^^ hope y'all understand the issue and can help me along.

ps. the monitor is not being detected by windows device manager, and not in control panel.

ps1. unplugging power for couple minutes, replugging, did not work

ps2. HDMI on 3rd monitor works fine

 

The reason i don't run HDMI is cause i have 2x 144hz, 1x 240hz, therefore displayport is needed
