HD4600 No 4K60hz via Displayport 1.2

[Edhawk]

ThE number of connectors supported depends on the framebuffer being used. The default HD4600 framebuffer supports 3 connectors. A couple of the mobile framebuffers support 4 connectors. See the link below, it will take you to a table showing all the Haswell/Azul framebuffer options.

If you look at the Spoiler link below the table, it shows which connector types are set by each framebuffer. The default framebuffer provides/expects 3 x DisplayPort connectors.

One of the other Desktop framebuffers may provide a better match to the connectors on your motherboard. Or you can use this information to edit the current connectors to better match your needs.

I started with identifying all the connectors on my motherboard, Hackintool detects 4 connectors: 3xDP and 1 | dummy.

I have read that macOS only supports 3 dispay outputs via a iGPU.....
My motherboard has 4 display connectors = DP(1x DP, 1xVGA) & HDMI(1xDVI, 1xHDMI).

So how do i even find a desktop framebuffer with 4 connectors ? Or do i need to use a Framebuffer with 3 connectors, and just ignore the dvi or vga port ?

And i can not connect a second display, i get a kernel panic when i plug in a hdmi screen, when my stystem is fully booted up(i use a primary 4k screen via DP: index#1 = 0x05 pipe 18 DP)

I don't know how to figure this all out...

I think i need to use a mobile framebuffer, because i need 2x DP and 1X HDMI. I have identified my DP, HDMI, and DVI-dual link port with IOreg explorer.
And i think i can not use my VGA port ?

I tried modifying the 0D220003 framebuffer.

i have attached a screenshot of my current PciRoot(0x0)/Pci(0x2,0x0)

Con0 DP = 01 05 0900 00040000 87000000
Con1 DVI-dual = 02 04 1000 04000000 04000000
Con2 HDMI = 03 06 0800 00080000 00000006
-----------------------------------------------------------
HDMI & DVI = type HDMI = 00 08 00 00
DP & VGA = type DP = 00 04 00 00

I realy do not know why it can be so hard to get 4k to work, all the ohter resolutions are just working fine (1440p 60hz, 1080p 60hz )
