Title:
  Secondary screen detected but black screen with Intel UHD graphics on
  kernel 5.9

Status in xorg package in Ubuntu:
  New

Bug description:
  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

  This is my lspci
