I just bought this pc a few weeks ago and everything worked perfectly. Unfortunately suddenly the displayport stopped working. Other thunderbolt functionality's still work as i can charge and transfer data using my phone with the 2 type c ports. A temporary workaround included using driver diagnostics in MyAsus, which then showed an windows update that fixed the problem after every boot. But now it does not show an update anymore. I made every update possible, windows, myasus, armoury crate, bios and even manualy downloaded drivers from the website.
Yesterday i reinstalled windows all over again and the secondary display worked, until i made windows, myasus, armoury crate updates and restarted the pc. I want to do a bios downgrade because i've red that that might fix the issue. I am desperate for a sollution so i can use my pc normally. Maybe it's worth mentioning that hdmi output works fine. Please help. Some more info:
