  • Are you sure that monitor is connected correctly? Can you hook it up to another computer to check if it works? Apr 28, 2020 at 20:21
  • FWIW, xrandr output doesn't even mention VGA. Are you sure you use VGA connector or rather DisplayPort? Apr 28, 2020 at 20:22
  • @ArkadiuszDrabczyk I have ubuntu on the same machine and it works perfectly. May 9, 2020 at 22:07

Instead of connecting Monitor 2 to the motherboard video port, connect it to another port on the 1050 Ti, which has multiple ports.

  • this 1050ti has only one HDMI and 2 DP, My monitor doesn't have DP. May 9, 2020 at 22:02

Integrated graphics may not work if discrete exists. As mentioned, plug both monitors into the nVidia card.

[While I've been down voted for my answer, I have several computer for which this is true. Without specific mobo manufacturing part numbers, revision levels, BIOS version, and CPU specifics, it is entirely possible the integrated GPU on the Intel CPU is disabled.]

  • Welcome to the site, and thank you for your contribution. Since you already reference another answer in your post for the "actual" solution, you may want to edit your answer to include some details on why (i.e. under what circumstances) mixing of integrated and plug-in graphics cards can interfere to produce the problem described in the question; this could help others prevent such problems in the first place or give them advice on whether the solution presented here is applicable to their problem ...

  • both work perfectly on Ubuntu, and I have enabled integrated graphics from BIOS settings. May 9, 2020 at 22:05
