I have AMD RX VGA 11 APU (Ryzen 5 3400G), my motherboard is Gigabyte B450M DS3H V2.
The motherboard has 2 display outputs, DVI-D and HDMI, the problem is that when connecting my old (Samsung SyncMaster 226BW - 2009 version ) through DVI-D the screen turns black, so I'm using HDMI to VGA converter.
I've bought a new Monitor and made it as the primary screen through HDMI, and want to connect my old monitor as a secondary through DVI-D, but I'm stuck, and after many trials, I think that the problem is in the APU.
I tried:
- Update GPU drivers to the latest version.
- Update Motherboard BIOS.
- Rebooted my computer a thousand of times!
- Replaced DVI Cable.
- Tested the monitor on an old computer with DVI and it worked.
Any help would be greatly appreciated.
