Hi Everyone,

Long time listener, first time caller!

I have this problem and its driving me nuts! I really don't know what to do..

A little context, I just built my new PC this weekend and everything works flawlessly however there is one problem - when I shut down down PC, I have to turn off and turn on my monitor in order to display anything on the screen. When I restart it works fine and other functions, but only on booting up after shut down my monitor doesn't want to display anything.

Here are my parts:
Ryzen 3900x
B550 Tomahawk
ASUS TUF 3080 OC
Corsair 850RMX

Monitor: S3220DGF (using Display Port)

I've updated all the drivers:
  • Nvidia
  • Windows (using windows update & driver booster)
  • Flashed my BIOS to the latest version (not the beta)
I've also changed the Display Port cable to a newer one.

Please, any help would be much appreciated! I worked hard to build this PC and I feel like I shouldn't be having this issue.
