My ig platform id is: 0x191e0000. Shall I use the patch mentioned for skylake (which says its supported) and change the MB's to match with 128?

0x19e10000 data:
01030303 00002002 00005001

framebuffer size: 0x02200000 (34mb)
cursor bytes: 0x01500000 (21mb)
34+21 = 55.

Let's say you have set DVMT-prealloc to 128mb, you could easily go to 2x these numbers (as an initial try):

framebuffer size: 0x04400000 (68mb)
cursor bytes: 0x02a00000 (42mb)

Resulting patch:
Name: AppleIntelSKLGraphicsFramebuffer
Find: 01030303 00002002 00005001
Replace: 01030303 00004004 0000a002

I applied the patch, restarted with invalid ig platform id, everything was glitchy, restarted after rebuilding kext and kernel and changing to correct ig platform id, I still cant see the HIDPI option on 1080p and everything seems the same.

What do you mean "cant see the HIDPI option on 1080p"?
And what do you mean by "everything seems the same"?

Did you create a custom display override to enable the HiDPI modes you want?

Yes I created this file in this location /System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-4c83
(The file is not a plist, I just made it so I can upload it and you can see it)

Here is my boot log as well

Your file is wrong.
For each HiDPI resolution you want, you need two entries:
- one for the actual HiDPI resolution (eg. 1920x1080)
- a second for 2x the resolution (eg. 3840x2160)

Amazing.. You are a genius! Thanks!!

Unfortunately I still get a laggy launchpad... Seems like my graphics card is a potato.
What I noticed until now:
On charger, the cpu works faster (reaching 3.1Ghz per core) while on battery it reaches only 2.0GHz.
Launchpad is laggy only on HIDPI.

Might be due to incorrect ACPI configuration (looking at your bootlog, it looks wrong).
Also, you might try other SMBIOS.
