I’ve got a Radeon VII Sapphire plugging in a Gigabyte X470 Gaming 7 v1.0 board. No other cards but do have an NVMe SSD.
Motherboard BIOS is flashed to latest f40.
Chipset is latest off AMD site.
Windows 10, 64 bit (Enterprise, in trial mode). I can (and have) wipe and reload to work through this. Build 1809.
Monitor is Gateway 1920x1200 connected by its HDMI 2.1 port.
When installing the AMD display driver, as the slider gets close to half way, the screen goes black then comes back garbled.
It’s nearly unreadable but I’m able to bang around in Windows enough to uninstall “AMD Software” and reboot back to working view.
When it’s garbled, I’m able to see Windows thinks it’s set at 1920x1200 with no scaling.
The monitor “info” on-screen display says it’s receiving 2400x1200.
Is there a technique I can leverage to force 1920x1200 during the driver install?
