RX580 8GB HDMI Problem

[kaitho]

Got a Sapphire RX580 8GB SE that is using DP to my MSI Optix G27C monitor. When i try to run a HDMI cable instead, the monitor dont get any signal.

 

First i thought it maybe something with the monitor, but when i using my RaspberryPi, PS4 or Xbox via HDMI to the monitor it works straight away.

 

Okey, could it be my RX580? So i tried my old R9 280X, that wont work via HDMI either. 

 

But when i use another monitor it works fine, i have formatted, reseated the GPU and tried alot of different driver revisions. Nothing.

 

Bunch of different HDMI cables tried.

 

TL;DR: MSI Optix G27C Monitor with HDMI dont work on my computer, no matter what GPU.  Monitor works on other devices via HDMI, and GPUS works with another Monitor via HDMI.

 

Any ideas?
