Can you dump the full modelines with pixel clocks (xrandr --verbose)?  I
suspect the pixel clocks for 1920x1200 and 1920x1080 modes are close enough
that one of the monitors was able to tolerate a slightly incorrect pixel clock.
 Some monitors are more tolerant than others.  Projectors tend to be since they
usually support a wide range of signals from various inputs.
