    Yes, the external works perfectly like I have mentioned in https://www.tonymacx86.com/threads/unsolvable-black-screen-when-waking-from-sleep-on-mojave-10-14-3-lenovo-g50-80.271315/ I think it's really strange, I don't know why macOS cannot wake my internal screen, but the external is okay!

    You dont need to change DVMT prealloc, see https://www.tonymacx86.com/threads/guide-alternative-to-the-minstolensize-patch-with-32mb-dvmt-prealloc.221506/ and use whatevergreen is okay.

    Did the following: Delete all the values in Add Properties Use Graphics Tab for correct ig-platform-id 16160002 Replace Whatevergreen with IntelGraphicsFixup and IntelGraphicsDVMTFixup The display works well, but the black screen issue still exists.
