Your profile is missing information regarding your screen resolution.
Please fix as per FAQ.
If it is 4k, you will need CoreDisplayFixup.kext.
Other things to try:
- older version of IntelGraphicsFixup.kext (I have not tested the latest version, refer to my github site)
- you may need to inject EDID
- using an external monitor may be useful for the case your internal screen is not working
Did you ever solve this? I just picked one up to mess with and needless to say, the graphics aren't going well. DVMT is set to 64 and it will boot an external screen ok using 0x59120000 but I haven't been able to get acceleration on the internal display.
