I've just have new laptop from my work and I can't set up the dualscreen. It's not a dualboot, so I can't test on Windows if it works.

Actually my laptop recognizes the second screen however the screen is black and I can just see my mouse on the second screen. Each window can go in this second screen and I can interact with them but the screen is full black.

I tried different options using the nvidia drivers 435 and 440 however in this case I case only interact with the second screen and not the one on the laptop. This is all my tests and results:

  • Without Nvidia Drivers: dualscreen recognizes however second screen black but I can interact
  • With Nvidia Drivers 440 (recommended by the computer): I can only interact with my second screen and the one on the laptop is full blank
  • With Nvidia Drivers 435: no graphics interface.

Here my xrandr with my TV second screen (I'm at home):

Honestly I looking since 2 days for solutions on the net but I didn't understand everything and I couln't find the solution.

Do I have to do something with xorg.conf file? How can I set a dualscreen on this laptop please? I look at this thread : Ubuntu 20.04 does not recognize second monitor but I didn't find solutions at my problem.

  • Are you directly connecting your monitor HDMI out on laptop to HDMI in on monitor (no adaptors)? And have you tried lowering the refresh rate on the built-in screen? I see the built-in screen has 144Hz capability. I don't know, but perhaps this is causing output/driver issues on the second screen. I would try lowering to 60 or lower and see if that makes any difference.

  • I connecting directly without any adaptors. Yes I tried to change the refresh rate to 59.96 Hz and that doesn't solve the problem Jul 25, 2020 at 12:18
