I have connected my tv to my pc , so if I want to watch anything I use tv screen. If you try to do same thing with kodi it won’t work because it handles window management a bit different way. So you should do it like that:
- first open kodi on your normal monitor
- press “” and enter so it will switch to window mode
- drag and drop the window on your tv screen
- press “” and enter again so it will switch to full screen mode again
- now it is ready to watch!
