Problem after connecting Dual dvi

[rds93]

I was using a HDMI on my monitor and found out that I had to use my dvi cable to get 144hz. Turn off my pc, changed the cables and when I turned on my computer everything seemed okay, went to my screen setup, raised the frequency to 144hz and tried to open Fortnite

To my surprise it looks like this now: https://imgur.com/gallery/m8Mj5Go?s=wa

What did I did wrong and how do I fix this?

Looks like it was made for old fashioned red/blue 3d LoL
Does it look normal at lower rates? Perhaps the dvi cable doesn't support 144hz

Which monitor is this please?
