help w/ getting 4k/60hz (back) in 10.14!

6 posts in this topic

Recommended Posts

Hello friends! I need help getting my display to 4k/60hz again. Until I updated to 10.14 I had 4k/60hz working using intelgraphicsfixup + coredisplayfixup + this "KextToPatch". My prior technique has apparently been deprecated in Mojave so I've since switched to WhateverGreen. I have been struggling unsuccessfully for the last two days but haven't been able to display any resolution higher than 3840x1080. Clover menu and FileVault password entry screen are 4k resolution. 

 

Please help a fellow faceless internet user out! :(

 

my PC

Intel i5 "Haswell"
Asus Z87 board
Intel 4600 built in (no discrete video card)
Clover UEFI
FileVault2 FDE
latest MacOS, latest Clover
CSM disabled
iGPU prealloc in BIOS set to 64mb
ViewSonic 4k display connected via DP

clover config

Make sure you are using the most recent versions of Lilu and WhateverGreen.  If that doesn't work, you can try using IntelGraphicsFixup.  Just because it has been merged into the WhateverGreen project, doesn't mean it can't work anymore.  In my case, I have to use NvidiaGraphicsFixup with WhateverGreen if I want HDMI to work.  There hasn't been any conflicts yet using the 2 kexts together even though the readme for WhateverGreen says not to.

mnfesq, thanks for replying! I tried adding CoreDisplayFixup and IntelGraphicsFixup to WhateverGreen but, alas, no change. One interesting thing I discovered is that if I add CoreDisplayFixup and IntelGraphicsFixup but REMOVE WhateverGreen and keep everything else the same(i.e. inject intel=no) I will have 4k @ 60hz but with no QE/CI, graphics & monitor not recognized etc.

This is hard. :(

My head is aching from slamming into a wall for so long and hard(that's what she said!) but I have a development to report! I was able to adapt the "KextsToPatch" I was using prior to Mojave(see OP) to the new style and that has unlocked 4k/30Hz!

<key>Properties</key>
		<dict>
			<key>PciRoot(0x0)/Pci(0x2,0x0)</key>
			<dict>
				<key>AAPL,ig-platform-id</key>
				<data>
				AwAiDQ==
				</data>
				<key>framebuffer-patch0-enable</key>
				<data>
				AQAAAA==
				</data>
				<key>framebuffer-patch0-find</key>
				<data>
				AwAiDQADAwMAAAACAAAwAQAAAAAAAABgmRQ=
				</data>
				<key>framebuffer-patch0-replace</key>
				<data>
				AwAiDQADAwMAAAAEAAAgAgAAAAAAAACAmRQ=
				</data>
			</dict>
		</dict>

 Now I just need help getting 60Hz because I don't know how much longer I can keep this up. It's hard. :(

 I believe the key now is pixel clock so I've so far tried:

  • multiple different versions of standalone CoreDisplayFixup.kext
  • WhateverGreen solutions (-cdfon boot flag & <key>enable-hdmi20</key>)
  • in terminal: "sudo update_dyld_shared_cache -force" which has helped in the past

no dice. :(
