Dell UP2414Q and 2013 MacPro
After today's update didn't automatically get my displays running at 60Hz I did some more digging. I am connected with Thunderbolt->MiniDisplay Port.
You have to manually turn on DP 1.2 support on the display itself. Now I am running at 60Hz.
This disables the ability to rotate the displays. Kind of inconvenient, because I was running one of them rotated 90 degrees. But I can live with it. I'd rather have the 60Hz.
The resolutions it's allowing me to select are:
1504 x 846
1920 x 1080
2304 x 1296
2560 x 1440
3008 x 1692
I do think it's strange that I can't set it to its native 3840 x 2160. But honestly, I couldn't hardly see anything at that resolution. The 3008 x 1692 works great.
Safari seems snappier at 60Hz.
