Hello macrumors
Just installed a RX6900 XT in my Mac Pro 7,1.
Using displayport with a InnoCN 27m2v monitor
Anyone knows how to solve the issue?
The cable clearly works as Windows happily will push the image so I'm confused to why OSX is refusing to sling anything but 60 Hz.
I've tried removing the Vega Pro 2, no difference either.
Tried a bunch of different cables in OSX
Tried SwitchResX but since only HBR2, no way to push the parameters.
