How TV can show ORIGINAL laptops screen using HDMI?

  • 772

I connected my TV and laptop using HDMI cable. In the terminal I typed xrandr command. The Ubuntu Desktop GUI appeared on the TV screen.

Based on my understanding, the screen shown on the TV is the second laptops panel. When I go to Settings - Screen Display, I see 2 screens:

  1. Built-in Display;

  2. Sony 46" (a screen to the right)

If I turn the Sony 46 screen off in the settings, the screen on the TV also turns off. What I want is my TV to show the first Build-in Display screen.

How to do that?

  1. As it is written, what you want to do exactly is unclear.

    If I understand correctly, you just need to check the "mirror displays" option.

    Go Settings > displays:

  2. If I understand you right, you want to mirror your displays

    To do that, open Settings > Display, and just tick Mirror Displays option.

    If you want to do that in terminal, run the following command:

    xrandr --output builtindisplayname --same-as 2nddisplayname

    Now it should work
