--- Comment #3 from Andy Furniss adf.lists@gmail.com --- 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.
