R9 290X
Hello, i am for quite long time here on the forrum into the Hackintoshes and troubleshooting my builds and always find a solution but i have recently upgraded my monitor to Samsung UE590 4K 60hz. And the problem is that i have ATI RADEON R9 290X reference card that i really love how it is behaving with final cut pro. In Mojave its well supported i can use dual monitors etc... but now when i have upgraded to my new monitor over hdmi i can get it running 4k but only 30hz which for me is unsuportable but when i connect to display port i have black screen but on this monitor only way of getting 4k 60hz is through DisplayPort i dont know does it matters that my gpu is shown as hd 8xxx in about this mac or what. If there is a solution to change something in clover configurator or somewhere if somebody know i will be very grateful for the informations.

Best regards

And by the way these are my specs
Intel Core i5 4440
2x8GB kingston 1600mhz RAM
ATI RADEON R9 290X reference
Gigabyte GA-B85M-D2V
And i run the latest Mac os x mojave with clover bootloader
