Do you know why xrandr rounds up to "3840x2160 59.97" but the
lubuntu GUI says "3840x2160 59.9685"?
I thought it might be the TV only does 30Hz or 60Hz but it does
fractional rates at lower resolutions.
I don't know.
Maybe it is the colour depth.
Why is my first monitor 1920x1200 for :Width" and "Height"?
