- Msi R9 390X
- Mobile Phone
I have a R9 390 from sapphire and had a lot of issues with it since High Sierra.
But I got it running.
I did the following.
- selected igpu in bios as primary
- connected the igpu to the monitor via VGA cable
- connected the r9 390 to the same monitor via HDMI
- booted with the following options in graphics section:
Load Vbios= yes
And then for the igpu I also selected inject and changed the id:
Boot it up, switch to second input on the monitor, log in and it will show you 2 monitors in settings menu...I then selected the hdmi input as "main" screen.
Tried this method and it didn't work in HS....
For now I am giving up on getting this card to work with HS....I put my R7 270 back in and threw the 390X back into my Windows rig...
Thanks for trying to help out...I appreciate it...
Take it easy
