Comment # 3 on bug 104660 from Andy Furniss

Thanks, that works.

This is the same with non dc, but is there a reason they are a bit low?

  1920x1080 (0x5b) 285.500MHz +HSync -VSync
        h: width  1920 start 1968 end 2000 total 2080 skew    0 clock 137.26KHz
        v: height 1080 start 1083 end 1088 total 1144           clock 119.98Hz

 1920x1080 (0x5c) 260.250MHz +HSync -VSync
        h: width  1920 start 1968 end 2000 total 2080 skew    0 clock 125.12KHz
        v: height 1080 start 1083 end 1088 total 1138           clock 109.95Hz

 1920x1080 (0x5d) 235.500MHz +HSync -VSync
        h: width  1920 start 1968 end 2000 total 2080 skew    0 clock 113.22KHz
        v: height 1080 start 1083 end 1088 total 1133           clock  99.93Hz

I was hoping DC would differ from the old driver in giving exact Hz for these.
