Display Port output "flashing" from POST until Logged In

Continuing the discussion from Fedora 38 - Kernel 6.3.X - AMDGPU Display Not Working Correctly:

Not sure if it is the same issue, but what I experience is different.

My mini-computer is using AMD 5600G cpu - with 3 video outputs. I use 2 of them - Displayport and HDMI in a dual monitor setup.

The HDMI is working normal. Only the DisplayPort is problematic.

The problem is there even if HDMI cable is unplugged.

But once I logon to Gnome, the flashing stopped.

You wanted to say that the HDMI is working normally ?

Thank you for the reminder. I meant that DisplayPort monitor is flashing in dual and single monitor setup.

At the end of the day, it is the monitor hardware problem.

Both HDMI / DisplayPort input of the Monitor is having issue. (HDMI works initially, but also flashing after a few days.) Now, only VGA works with that monitor.

As a comparison, another monitor works with DP/HDMI/VGA from the same cable/computer.
