One screen blank

dbartolini

I have a SER3 Ryzen 7 3750 H Based beelink micro computer. Originally when
> I got this I was able to plug-in two monitors and work as normal.
> Starting yesterday one of my monitors went blank however it appeared
> that the monitor was still rendering and it still showed up as a
> second monitor in display settings and in the Radean software.
> Strangely when you reboot the computer, blank monitor shows the bios
> screen then goes black again and the other screen shows the login for
> windows (10). There appears to be some sort of common problem
> according to Google and these blogs however I haven’t been able to
> find a solution. I have uninstalled from safe mode and then ran the
> clean up utility. Then I reinstalled the suite and have the exact same
> problem with the exact same monitors. The set up that was operating
> first had an HDMI to one monitor and an HDMI to Vega on the other. I
> have replaced all the cables with the same results. I swapped the Vega
> monitor for another HDMI monitor and got the exact same results again.
> No matter what I try I cannot get both monitors on at the same time
> however they are both detected. I’ve rolled back drivers after
> Deinstalling and running the cleanup utility between each iteration.
> Same results one screen on one screen black always the same ones. I
> played with the cooling fan - no changes. I’ve restored images from a
> month ago no changes. I rolled back drivers with no change. I am at
> wits end. I am running windows 10 pro (10.0.19043), and the Ryzen 7
> 3750H With the bios edition APB20104, 9/11/2021. I have 16 gigs of
> memory, the Adrenalin version 2020.22.1.2. The Vega 10 graphics Driver
> version is 30.0.1402 3.3004.
