Bug Description

mirout says:

Output 19: Card 0, HDMI-A, connected, 1920x1200+0+0, used, on, 520mm x 330mm (24.2"), normal
    1920x1200 60.0*+
    1600x1200 60.0
    1680x1050 59.9
    1280x1024 75.0 60.0
    1152x864 75.0
    1024x768 75.1 60.0
     800x600 75.0 60.3
     640x480 75.0 60.0
     720x400 70.1

Actually that first 60.0 is more like 59.94. It's just that we've rounded the result, both in mirout and also in:
src/platforms/mesa/real_kms_display_configuration.cpp: return round(vrefresh_hz * 10.0) / 10.0;

Then again, it's normal for the industry to knowingly refer to 59.94Hz as "60Hz", or 23.976Hz as "24Hz" etc. So low priority for now. Maybe even Won't Fix...
