I looked at that too. Almost every resolution and refresh rate has different parameters. So still don't understand, that only the 60 Hz's pixel ratio was fine by default and set to 1.000 in Kodi, and every other refresh rate's ratio was wrong and set to 0.952.

In LibreELEC, every refresh rate's pixel ratio is set to 1.000 and looks fine. Am I wrong, that I suspect some missing or mis-configuration? This is very odd to me.

wsnipex advised me to reset the calibrations. How can I do that?
