This is the framebuffer patch I use:

                <key>Comment</key>
                <string>Increase buffer for 4K (64 MB RAM / 48 MB Framebuffer)</string>
                <key>Disabled</key>
                <false/>
                <key>Find</key>
                <data>
                AwAiDQADAwMAAAACAAAwAQ==

Are you using Nvidia Graphics?

If so, do you use NvidiaGraphicsFix in conjunction with CoreDisplayFixup? Because when I have them both in kext-other folder, I dont get 60Hz options?

But if I dont have Nvidia Fix, I get black screen :/

@headkaze
Are you using Nvidia Graphics?

No, I'm not. My current config is in my profile. I included the latest version of NvidiaGraphicsFix in my uploaded files for others, but I cannot tell you if it works or not, sorry.

How can I check If lilu and coredisplayfixup is working ?

Anyone using HDMI 2.0 and 4k screen?
pixel pitch and coreDisplayFixup are not working at all..

No signal on my HDMI 2.0 4k screen, but my other monitor with DP+ 1080p is working.

How can I check If lilu and coredisplayfixup is working ?

kextstat | egrep "Lilu|CoreDisplayFixup"

thanks so much for this post.
only took me like months to get some joy from my 32 inch Dell 4k and hackintosh, bought it specifically for Mac OSX and it has been a nightmare until now

make sure you have backups of these mods.
i used this on 2 machines, one is ok, but one was very unstable and would 50% of the time boot to black screen while in past it was totally 100% perfect. i had to roll back. i used IOKit Patcher.
rolling it back brought back a perfect hack.

hi. could you explain this please?

hi. could you explain this please?

Depending on your hardware you may need to increase the framebuffer size for 4k support. There is also the IntelGraphicsDVMTFixup.

I don't need either of these patches with my new hackintosh.
