I recently bought an Asrock B450 Gaming K4 board (because it is one of the few to have both HDMI and DisplayPort connectors) and an AMD Ryzen 3400G. I did not get a dedicated graphics card but want to use the Ryzen's integrated one.

However, I got the problem that there is no sign via DisplayPort. HDMI works, but using DisplayPort, the monitor remains black and without a signal - from the moment when I press the power switch.

I tried upgrading the BIOS from 3.9 to 4.1, but that didn't help either.

Any ideas?
