HP 600 G3 Intel HD630: no 4K@60fps

[robi62]

ok today I tried a different approach I specified pipe and types in config but l gets connected as  dp but colours are violet and no audio with dp

What's the problem did I do something wrong ??????

I enclose config file ioreg 

Funny thing Hackintool thinks I am connected with HDMI???

forgot to mention on bootup no display got it after I fidgit with connector in and out a few times.

You now call upon KBL/ABL framebuffer 0x87C00000:

ID: 87C00000, STOLEN: 34 MB, FBMEM: 0 bytes, VRAM: 1536 MB, Flags: 0x0000078B

Your patches, as found in your posted Opencore config file:

i.e.

[0], busId: 0x00, pipe: 8, type: 0x00000200, flags: 0x00000098 - Connector Analog DVI
[1], busId: 0x05, pipe: 9, type: 0x00000400, flags: 0x00000187 - ConnectorDP
[2], busId: 0x04, pipe: 10, type: 0x00000400, flags: 0x00000187 - ConnectorDP
00000800 00020000 98000000   --> analog DVI connector type
01050900 00040000 87010000
02040A00 00040000 87010000

 

Other than the strange patch of connector type 00020000 for con0 (which does not matter because con0 is not used, IOReg showing screen attached to con2), I fail to see the relevance of your other patches given that the values you inject are exactly the same as those natively defined in the framebuffer. As such, you most definitely do not patch any connector's pipe and you most definitely do not patch any property of the connector used for your LG TV.

 

Since that you've now opted for a KBL/ABL framebuffer which attaches your screen to con2, why don't you just adjust con2's pipe to 0x12?

framebuffer-patch-enable        1               NUMBER
framebuffer-con2-enable         1               NUMBER
framebuffer-con2-pipe           12000000        DATA
