AMD/Nvidia Primary Display with AirPlay Mirroring

[iltenente]

Hi, my hackintosh is the one of the signature, bootloader is Clover 3142 the display is connected to the GTX 770 using the display port and I've an ATV2 jailbreaked. I've followed this guide and, using in clover Framebuffer: IGPlatformID=04120004, I've not the airplay icon, changing to 0x04120004 I've the icon but in System info Graphics I can see only the GTX, removing IGPlatformID value I've the icon and in System info I can see GTX and HD 4600. When airplay mirroring is active, the tv connected to atv2 become black, only audio is ok. I've tried to reboot pc, ATV2, switch on and off airplay mirroring very rarely it worked but usually it doesn't work!
P.S. Ten minutes ago, as usual, black tv display but after rebooting atv2 and activate AirPlay, all works.
Is there a way to make it work in a more simple mode?

a. changing to 0x04120004 I've the icon but in System info Graphics I can see only the GTX,
b. removing IGPlatformID value I've the icon and in System info I can see GTX and HD 4600.

a. Correct.
b. Incorrect.

I tried again:

a) black screen rebooting ATV2 too
b) works rebooting ATV2

I know it's wrong but b) works sometimes!
I'm sorry but I don't understand.

Try the Post #1 method exactly as documented. Different steps based on bad assumptions never work. For both integrated and discrete, see Post #1 link.

Hello from germany

i tried the guide in post#1, with clover inject and also edit dsdt. the symbol is available, but i can't activate display mirroring.
Non-HD streaming works from iTunes.

hardwareconfig: GA-H97-HD3, Intel i7 4770k, 8Gb crucial tactics and MSI nvidia GTX760

softwareconfig : yosemite 10.10.2 with clover and ssdt for speedstep.

any ideas?

Clover did not inject ig-platform-id=0x04120004, try 04001204

try 04001204

Hardware>Graphic/Display now shows HD4600, thats wrong i think. airplay symbol is gone

i'm pretty sure i had my airplay working, but lost it when making iMessage work and can't get it back. also, if your brain has any insight as to why certain gestures don't work on my magic trackpad, i'd really appreciate it it! i can't zoom, rotate, or two finger navigate in safari. not major, but frustrating!
