Spoke too quickly.

Here is what it returns:
  1920x1080 (0x10d)  103.7MHz *current
        h: width  1920 start    0 end    0 total 1920 skew    0 clock   54.0KHz
        v: height 1080 start    0 end    0 total 1080           clock   50.0Hz
  1920x1080 (0x10e)  105.8MHz
        h: width  1920 start    0 end    0 total 1920 skew    0 clock   55.1KHz
        v: height 1080 start    0 end    0 total 1080           clock   51.0Hz
  1920x1080 (0x10f)  107.8MHz
        h: width  1920 start    0 end    0 total 1920 skew    0 clock   56.2KHz
        v: height 1080 start    0 end    0 total 1080           clock   52.0Hz

See that the refresh rate don't match the reality: it goes from 50 to
112 etc.. all incrementing by 1.
This is due to nvidia generating unique refresh rate...
