Help with HD4000 on a 6 series board

[LockDown]

Hi

I have a generic All-In-One PC with HM65 Board (6 Series) & HD 4000 IGPU with LVDS bult-in-display connector.

 

What i have done so far:

1. inject IMEI 1e3a8086 in config.plist  (since its a 6 Series).

2. Grabbed EDID in windows because clover cannot detect it.

3. Tried ALL framebuffers but only 01660004 let me login to desktop. The rest are all blackscreen.

4. Used Fixedid to edit my EDID but results are the same

 

But the problems with 01660004 is, im having a bad graphics even i have full acceleration.

 

System Profiler show that i have Full acceleration

 

The rest of framebuffers that i tested gave me blacscreen. Tried using VNC remote to check but there was no acceleration. It seems that only 01660004 work on my system.

 

Any thoughts?
