Make sure when you're testing IGPlatformID that you are NOT using a patched DSDT and *ARE* using IGPEnabler=Y or GraphicsEnabler=Y.

These techniques are mutually exclusive:
- patched DSDT with graphics injection. IGPEnabler=No and GraphicsEnabler=No
- no DSDT patches for graphics injection. IGPEnabler=Y or GraphicsEnabler=Y and IGPlatformID to select the platform.

Also, it might be useful if you got a PCI inventory from DPCIManager or 'lspci -nn' on Linux.

Finally, some laptops need EDID injection for the laptop display to work. And your laptop display could be dual-link (I've seen one low resolution laptop with dual-link) which requires a different approach (DSDT injection with AAPL,DualLink=1).

When testing the combinations, you must be systematic, deliberate, and detail oriented.

In all cases, try plugging in an external monitor via HDMI. If you get a signal there, capture ioreg: http://www.tonymacx86.com/audio/58368-guide-how-make-copy-ioreg.html

You have a big problem with your install then... Suggest a fresh install being careful about what you install... Without more information about what you did, I can't offer any other advice.
 
this is the problem I do not do anything out of the norm.

with UniBeast install and reboot with-x
I install multibeast with chimera ps2 kext and voodooohda
I copy my dsdt in the extra folder and PlatformID for the HD4000 starts.

Optimal resolution and everything works smoothly.

Except that when I try to open about this mac the finder crashes

VoodooHDA is known to cause issues. What else did you install with Multibeast? I ask because installing only "ps2" and "voodoohda" is not enough to boot most laptops with correct power management. See here: http://www.tonymacx86.com/mavericks...nagement-sandy-bridge-ivy-bridge-laptops.html
