Hi! I have an HP ProBook 440 G7 with i7-10510U and INTEL UHD GRAPHICS.
The problem:
When i connect to my external monitor (a Samsung BX2250) via HDMI, the
screen is detected (i can see it in display settings) but the external
monitor remains black. Seams like a bad frequency or resolution. I tried
adding a new mode to xrandr with no luck. Also i tried different
versions of kernels from 5.4 to 5.9.
I am using Ubuntu 20.10
