GA-Z77-DS3H + HD4000 HDMI Problem

Hello,
I've managed to setup HD4000 with DSDT Editing using ig-platform-id: 0166000A on a GA Z77 DS3H motherboard with i5 3570k. (DSDT fixes + patched AppleHDA)
I have full acceleration and HDMI audio using HDMI output to my Sony TV.
The problem is that it boots fine with 1920x1080 BUT if i try to change resolution to something lower than that everything gets messed up.
The only way to have correct resolution change is to put computer to sleep and after wake everything is OK i can then change resolution to anything i want ,after reboot the problem appears again.
I also tried with DVI to HDMI adaptor but same issue.



Tried with latest chameleon from http://chameleon.osx86.hu Chameleon-2.1-r2069.pkg.zip and latest Chimera.
Bios settings have been checked and Graphics Enabler in boot loader is disabled.
Also tried with out any dsdt and Graphics Enabler = True in Chimera but same results.

Tried also MacPro3,1,MacMini5,1 and iMac12,2 if i remember correct.

Any help will be appreciated.

Why are you trying to do that? The only lower resolutions the TV supports are 720P and, perhaps, 480p and that is automatic based on the source content.

As i said if i put the computer to sleep after wake everything works fine.
I can lower the resolution to anything without a problem.

I believe that 0a framebuffer its the problem cause last night i ve tested clover bootloader with uefi boot and graphics injection without dsdt and everything was ok. But i lost hdmi audio.

In ioregistry i saw that clover injects the ig-platform-id: 01620005

After hours and hours of trial and errors i came up with Chimera + dsdt + macmini5,1 smbios.
Everything is working except the resolution change that still works ONLY after wake from sleep.

I give up.
Here are the files for anyone with better knowledge to assist.
