Hi.

Anyone knows how to solve this? I updated my Hackintosh to Ventura, and now my Dell U4021QW runs at 30hz. I can't select 60hz when I choose full 5120x2160 resolution.

It is connected via DisplayPort from my Radeon RX 570.
 
Nevermind. I fixed it by changing some Radeon/LoadVBIOS arguments in Clover. Don't know exactly which of them is responsible for getting it working but it does now:)
