...
etc., seemingly as often as the EDID is re-read/re-considered.
>From the first parameter of the Modelines one can already see that modes with
594.00 MHz clock are found, and indeed, the "3840x2160" mode at 60Hz is used,
as both xrandr and the connected display report:
HDMI-A-0 connected 3840x2160+0+0 (normal left inverted right x axis y axis)
1600mm x 900mm
3840x2160 60.00*+ 50.00 59.94 30.00 25.00 24.00 29.97
23.98
