virginiapatriot Posted February 20, 2016 Share Posted February 20, 2016 Thanks to Slice's suggestion of 0x66401002 now I've got my XFX DD R7 260x working under Yosemite with sleep and awake from a USB mouse click. The next thing is a higher resolution than 1080p which is not shown. This card can do 4k res at 30hz with HDMI how can we get 3840x2160 to show up? I don't have HDMI audio either. Update: I went to El Cap and the same modified kexts give 3840x2160 at 30hz...but no wake from sleep. Link to comment Share on other sites More sharing options...
Slice Posted February 24, 2016 Share Posted February 24, 2016 I have to remind that the problem with AMD Radeon wake from sleep in ElCapitan is still not resolved. No need to ask again. Link to comment Share on other sites More sharing options...
