Most laptops have a hardware keyboard combination to activate a secondary screen with/instead of the primary screen.
On a x86-64 machine, try to get the output of the 'xrandr' command in a terminal connection session when the 2nd monitor/TV is connected.
How ancient is the laptop? .. and what GPU is inside?

One other thing... Kodi only supports 'clone mode', which means it only does two monitors with identical resolutions.
Since your laptop "only" has a 1366x768 screen, you will be either seeing Kodi on the laptop screen or the 1080p screen/tv.
You could try forcing a 1280x720 resolution, that should work on both output. The display rate is (almost) similar.

I fixed all problems using this post (although didn't have to create an autostart script because it started detecting the display on a reboot don't know how or why it fixed itself. Quite frankly I don't know how to create an autostart script either so I'm glad ) problem second monitor. I also had another problem where it would get stuck at start screen failing to load xorg and I used the fix from this post [SOLVED] Failed to start Xorg Server help Don't know if this worked, seems like it did, only time will tell.
