Awesome!

The EDID of the monitor reports a larger total size and therefore a higher
clock for 1920x1080 than for 1920x1200:

Modeline 22:"1920x1200" 60 154000 1920 1968 2000 2080 1200 1203 1209 1235 0x48
0x9
Modeline 27:"1920x1080" 60 172780 1920 2040 2248 2576 1080 1081 1084 1118 0x0
0x6

Why the monitor would do this is anyone's guess.
