Intel UHD630 not showing 3840x2160 resolution

[Adrian0985]

Hi!

This is my first hackintosh build and everything works perfectly except I can't make my Dell 2718q monitor to work in full native resolution. The max available option is 2560x1440 and after I enabled HIDPI the max value with that is 1280x720.




I've done my fair share of googling but without luck.

Maybe somebody had this issue before?

You're using DisplayPort? HDMI will be limited by the motherboard @ 60Hz.

"Supports HDMI with max. resolution 4096 x 2160 @ 30 Hz"

Yes, I'm connected via DisplayPort on the motherboard and miniDisplayPort on the monitor. I strongly suspect it's some osx issue as up until the point when the apple logo shows the boot process is in 3840x2160 resolution...
