Anyone knows how to force a refresha rate xrandr does not show? I followed the instruction here: https://wiki.batocera.org/display_issues
Currently my setup is a mini-PC connected to LG OLED55B7V which support 120Hz refresh rate but does not report it through PnP. In Windows 10 I had to force it and lag is reduced to unnoticeable value. In Batocera and Ubuntu I failed to force 120Hz rate with xrandr.
