Maybe. Check in Windows (Intel graphics control panel) to see if your display uses eDP.

eDP is not supported by HD4000 in OS X.

Try all ig-platform-id values...
 
I don't find in Intel control Panel which port is in use

FIND IT,
Intel control panel tell LVDS port, so can you help me please,
i have extract my DSDT from ubuntu, with
cat /sys/firmware/acpi/tables/DSDT > DSDT.aml
iasl -da DSDT.aml

so with Maciasl i have patched it with graphics_Rename-GFX0.txt
and with graphics_HD4K_low.txt,
if i use a different ig-platform-id the boot stopped with error :

Debugger called: </SourceCache/GPUDriversIntel/GPUDriversIntel/Common/IONDRV/Intel/IVB/AppleIntelFramebuffer/AppleIntelController.cpp: Assertion failed: (0 == i) || ((pfbInfo->rangeStolen.physBase - pfbInfoPrev->rangeSt
>
Debugger not configured. Hanging

I forget where it is... but it is on one of the "information" screens. Look carefully and you'll find it. Make sure you have current Intel drivers.

Does your BIOS have any options for the IGPU settings?
 
No option for GPU,
and the vram inserteed in clover configurator is ignored from the kext.. in osx is always 1536 Mb

with other ig-platform-id if boot no qe/qi but hd 4000 with 4MB , whit 0x01660002 and same other the bott hang with
