Hello, I have this laptop

Chipset H76
Core i5 3210m
Intel HD 4000 (1600x900)
Nvidia 650m

I used frame 0x01660004, other frames don`t work, if i use with duallink=1 monitor is black. Without any framebuffer it starts normally but without acceleration. When i made EDID injection, my notebook stops on logo. Without EDID my screen is like on photo(blinked). Can someone help me?

as per rules, please update your hardware profile

wasn't aware windows 8 made motherboards

also you will need to upload your "Problem Reporting" files here

Samsung laptops (of your laptop era/Ivy/Sandy) are notorious for this.
You might try implementing backlight control and see if it helps.

Also, the ioreg doesn't correspond to the EFI/Clover you attached. The config.plist there is doing EDID inject, but no sign of it in your ioreg.

There is no EDID in ioreg, because if i`m booting with injecting EDID, it`s not fully loading, so i can`t enter system

I tried different connectors with different framebuffers, no result. It`s only 0x0166004 framebuffer works, with it`s own connector. I don`t know what to do else...

Problem is the files you provided *are* injecting EDID, which does not correspond to what I see in ioreg.
It invalidates the entire EFI/Clover as clearly that is not the EFI/Clover used to produce the ioreg.

I think you mean 0x01660004, not 0x0166004 (0x0166004 is invalid).
It is typical that 0x01660004 is required for 1600x900 and greater with HD4000, so nothing surprising there.

Did you implement backlight control yet? (as suggested)
 
Yes, I mean 0x01660004. I can`t make backlight control, with intelbacklight.kext it`s not starting(img_0488), with clover PNLF fix it`s kernel panic (img_0489). I think my Samsung screen has sDP connection(((
