4k Haswell requires larger DVMT-prealloc (likely at least 128mb), plus framebuffer patches to match.
And -cdfon for WhateverGreen.kext.

By framebuffer patching you mean config.plist->device->properties->framebuffer-* right?

Do I have to go with an msbios from MacBook pro or qhd will work with MacBook air also?

Yes, of course.

No such thing as 'msbios'. Perhaps you mean SMBIOS.
You should use MacBookAir6,2 or MacBookPro11,1.

I got no luck on finding how to set framebuffer patches to match 128mb of DVMT-prealloc

<key>framebuffer-cursormem</key>
<key>framebuffer-fbmem</key>
<key>framebuffer-stolenmem</key>
<key>framebuffer-unifiedmem</key>

Which of the Framebuffer properties corresponds to that one?

Refer to config_UHD.plist in the y50 repo on my github.
It uses a 128/48/48 configuration.
 
It seems like I will have to live with 21mb vram.
I got into a setting where I just got the very broken login screen.

Any idea why the device id freaks it out and gets it to kernel panic?

Keep in mind you *must* set DVMT-prealloc to 128mb before attempting to use the 128mb DVMT patches.

Was thinking of trying the whole thing once more with
Your hd4400 config.plist
fakepciid
fake Intel hd graphics
intelgraphics fixup
and lilu
(Sorry for the partial naming, I'm on my phone now)

Would the above even work or for Mojave or whatevergreen is the only way?
