Hi!
I have 2 monitors connected with DP.
I only get outputs on my dGPU's DP ports, not on my onboard outputs (DP and HDMI) AND not on my RX 5700 HDMI port. (I have drivers installed and it's not working from BIOS)
Once I got signal from my mobo outputs, it's just bad.

It's worked on a day, then not on another day.
Then I brought my TV to test it's HDMI, and it worked on my RX HDMI (with some flickers so not fully) , but not on mobos DP and HDMI.
I don't have any performance issues .
Maybe it's a power issue? For example my PSU is dying? I don't really know at this point.
my full specs is in my signature.

BIOS is up do date, and in bios settings I enabled iGPU with 128M DVMT, set Primary to iGFX
The really interesting thing is that on my RX 5700 every port are working but not the HDMI...

I checked the tv & monitor with my notebook and there was no problem.
There the pictures I take:
