HP Recommended
Operating System: macOS 10.14 Mojave

I cannot get an HP Z27xs G3 to display 4K 60hz on Mac Pro 2013 running Mojave. I can only get 30 hz. I'm going from DisplayPort to a thunderbolt port. I've used a DisplayPort to Mini DisplayPort cable, and a DisplayPort to Mini DisplayPort adapter, with the same results. I've also tried HDMI to Mini DisplayPort adapter.

 

When I swap out the Mojave OS drive for a Ventura drive, I am able to get 60 hz. But I need to run Mojave because the editing software I'm using can't run on Ventura. I've tried the program EasyRes for Mac, but it also doesn't give me the option for 60 hz at 4K.

 

Any suggestions or questions?

 

Thanks
