Question Random black screens but the PC keeps running ?

[bedouinbro]

I'm getting a random black screens and no audio from the monitor, The PC keeps running the monitor loses signal, and its light indicator keeps blinking ( I always keep it on the standby mode so no LED indicator when using PC ). I also use unified remote app, and Chrome Remote Desktop.

When the display loses signal I can see the mouse cursor and all the processes running, and if I use Bluetooth I get audio from headphones. whats causing this ? I posted several weeks ago in the "Displays" forum with detailed stress testing here:
