well whatever i try it didnt work out for me, even swapping the nvidia drivers (and yes i used DDU)
I wiped all drivers multiple times, tried several DVI-DL(DUAL LINK!!!) cables (yes im aware of all the cable types! Single Link, Dual Link, Analog, Digital !!!!)
For now i tried with an Displayport to DVI-DL cable (dp on the GPU side, DVI-DL on the Display side) and i tried every DP port on my GPU
