One of my Dual Monitors is randomly recognized with AMD Ryzen™ 3 PRO 2200G Vega 8 Graphics using Radeon Adrenalin graphics software, November 2020 edition. Totally frustrating, since the software does not recognize the Envision AOC 2219-1 22" monitor about 4 out of 5 boot ups of my HP EliteDesk 705 G4 SFF computer running Win 10 Pro. It only recognizes the ACER K242HYL 24" monitor.
I have tried removing and reinstalling the driver and the Radeon Adrenalin software to no avail. I have searched online for help without finding anything to help. The basic issue seems to be that the monitor is not recognized by the software and there seems to be no way to manually set the parameters for the AOC monitor. FYI, the AOC monitor performed correctly on my older Dell 780 with Win 7, using a Radeon PCI card and the Catalyst software.
