@Daniel: That current mode is from the xrandr.txt when the working 2560x1440 resolution is set. Lionel and I got the 23.98 Hz figure from monitors.xml that I generated after the 1920x1080 change is applied and the monitor has no signal.

[Desktop-packages] [Bug 1892296] Re: gnome-control-center cannot change resolution of external monitor
But why does g-c-c choose the lowest frequency refresh instead of the highest?

No, that doesn't help - the screen stays blank if I set it to 1920x1080 using g-c-c and then run the set max bpc command. I also tried setting 1920x1080i using xrandr in case that's what g-c-c was choosing but it worked fine. With the 1920x1080 setting chosen in g-c-c (and the monitor consequently getting no signal), this is what xrandr says for HDMI-1: HDMI-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 597mm x 336mm 2560x1440 59.95 + 1920x1080 60.0050.0059.9430.0025.0024.0029.97 23.98* 1920x1080i60.0050.0059.94 1600x1200 60.00 1280x1024 75.0260.02 1280x960 60.00 1360x768 60.02 1280x720 60.0050.0059.94 1024x768 75.0370.0760.00 800x600 75.0060.32 720x576 50.00 720x576i 50.00 720x480 60.0059.94 720x480i 60.0059.94 640x480 75.0060.0059.94 720x400 70.08 ie it looks like g-c-c has chosen a mode that doesn't actually exist for xrandr, because none of the modes have an asterisk next to them.
