Intel HD6000+/HD5000/HD4600+/HD4000/HD3000 Framebuffer Edits
I had HD4600 work out of the box on Clover but DisplayPort was stuck giving 1080p to my Philips 288P screen that prefers 4K @ 60Hz.
- El Capitan 10.11.1
- Z97 (Asus Impact VII) - It's great to have the same board as toleda
)
- Devils Canyon 4790K HD4600 integrated graphics
Before the patch I tried the following with no luck on resolutions,
- I applied pixel-clock
- kext patch edits: config-hdmi_hd4600-100.plist
- ig-platform-id -> 0d220003
Then the following made the native 4K/60Hz on Philips 288P work over Display Port:
<dict>
<key>Name</key>
<string>AppleIntelFramebufferAzul</string>
<key>Find</key>
<data>AwAiDQADAwMAAAACAAAwAQ==</data>
<key>Replace</key>
<data>AwAiDQADAwMAAAAEAAAAAw==</data>
<key>Comment</key>
<string>framebuffer4K</string>
</dict>
This according to rael11 boosts the RAM Allocation to 64MB and the Framebuffer Memory Size to 48MB. I also had BIOS to allocate 64MB.

Confirm all working and native resolution 4K working @ full 60Hz over DisplayPort and all with just the HD4600 integrated GFX.
