I recently went through the process of setting up Lilu and Whatevergreen to fix kernel panics I was having on sleep with my Intel HD 4600 running on an ASUS z97i-plus motherboard: https://www.tonymacx86.com/threads/kernel-panic-when-sleeping-or-idle-mojave-10-14-2.274515 and was able to resolve the kernel panic issue, but am now running into another problem.

I have two monitors connected:
  1. Apple Cinema 23" connected over DVI
  2. Dell U2414H connected over displayport
Following An iDiot's Guide To Lilu and its Plug-ins, I was able to get the iGPU working correctly and without any more Kernel Panics on sleep, but I'm now encountering a bit of an odd issue where on boot, my cinema display has a black bar at the bottom of the screen:

Oddly enough, the resolution in the display settings is indeed correct for the cinema display (1920 x 1200 at both Default for display and scaled):

396833


The iGPU is showing up correctly in 'About This Mac' as well:

396834


Adjusting the resolution causes severe distortion and is unusable:

The very odd thing is, I can do the following after booting:
  1. Sleep computer
  2. Wake computer
  3. Cinema display is now correctly scaled
  4. Dell display is no longer detected
  5. Turn off dell display
  6. Turn dell display back on
  7. Screens are detected and readjusted, and everything works
Obviously it is not an ideal solution, does anyone have any tips on how to proceed?

Ok, after some further research, disabling CSM support in my BIOS fixed things. It took two reboots for some reason. After I first disabled it, my hackintosh booted into what looked like 320x240 resolution with interlacing for some reason, but on a second boot, everything was fine.

Actually I spoke too soon. Disabling CSM did not fix it, it actually caused the screen to frequently boot into the weird resolution, and kernel panics if I plugged anything into the HDMI port:

The relevant part of the crash report seems to be:

Well, like several others that struggled to no avail with the Intel 4600 I bought an RX 580 and put the iGPU dream (and the dream of a nearly silent computer) to rest.
