1920x1200 (0x70)  154.0MHz
1920x1080 (0x72)  148.5MHz

These two pixel clocks are close enough that your monitors seem to be able to
deal with the slight difference.  Unfortunately, not all monitors are so
forgiving and and it wouldn't work if you picked a mode with a substantially
different pixel clock.  You just happened to get lucky.
