I didn’t manage to launch Batocera in FullHD with my 4K TV. It has no real interest. Most games and videos are lagging (even the batocera intro !). I can change the resolution in Kodi, but it doesn’t work : the screen is cut off, borders are missing…

it works (the TV displays 1080p), but the screen flickers, it is unusable: the frequency rate seems to be not compatible with the TV… and I don’t know how to set it.
