I'm using ubuntu 20.04 and with Intel UHD Graphics 630, the second monitor is detected but it's all black, does anybody know how to fix this issue?

  • Is the resolution set to the correct (native) one? Sep 1, 2021 at 16:32
  • Yes, everything correct, really, didn't understand what happened, something driver related low-level for sure, installed a gpu to solve the problem xD Sep 8, 2021 at 21:01
  • Same here, with similar GPU: VGA compatible controller: Intel Corporation UHD Graphics 620 (Whiskey Lake) (rev 02). The external monitor is detected as per the output shown by xrandr but the output is black. Did you solve it? Jun 23, 2022 at 12:12
