Created attachment 136779 [details] dmesg with error R9 285 Tonga, I see in agd5f 4.17-wip there are commits to do with DVI dual link. I was hoping "Don't block dual-link DVI modes" would enable 120Hz my monitor supports, which has always worked with without dc. There is an error in dmesg - don't know if it's related. dmesg and xrandr attached. [drm:dal_bios_parser_init_cmd_tbl [amdgpu]] *ERROR* Don't have set_dce_clock for v0
Created attachment 136780 [details] xrandr with missing > 60Hz modes
Created attachment 136782 [details] [review] Fix for dual-link DVI modes The error is unrelated. This patch should fix your dual-link DVI modes. It's hitting the mailing list soon, just took a bit longer than the rest of the DVI patches. Note that we also see issues with non-native modes on one display with this patch, but that's likely a monitor-specific issue.
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.

Those are the modes from the EDID from your monitor: CEA extension block Extension version: 1 0 8-byte timing descriptors Detailed mode: Clock 235.500 MHz, 521 mm x 293 mm 1920 1968 2000 2080 hborder 0 1080 1083 1088 1133 vborder 0 +hsync -vsync Detailed mode: Clock 260.250 MHz, 521 mm x 293 mm 1920 1968 2000 2080 hborder 0 1080 1083 1088 1138 vborder 0 +hsync -vsync Detailed mode: Clock 285.500 MHz, 521 mm x 293 mm 1920 1968 2000 2080 hborder 0 1080 1083 1088 1144 vborder 0 +hsync -vsync
Thanks, stupid monitor rather than some rounding then :-)
