cinnamon missing screen resolution tool

i am using a TV as main screen but it starts with 1360x768 instead of 1920x1080.
on other DE i use the resolution tool to set it to fullhd and the DE memorizes it.
using cinnamon i call xrandr -s 1 everytime i reboot.

i’ll check arandr

also, indeed the notebook lid gets fullhd with no struggle.
