Pink and white vertical bars across screen High Sierra on laptop

  • Hello! I'm installing macOS High Sierra on my laptop HP ProBook 4730s. I'm installing it by "OpenCore install guide" by Dortania. As i see my hackintosh works well, except one thing - there are wide pink and white vertical bars across the screen (by the way, sometimes when i run macos the bars are green and white). (of course my screen doesn't have them on Windows)

    Dortania's guide names it scrambled screen on laptop. The guide says i should enable CSM in my BIOS to solve it. But the problem is there is no csm (or sort of) option in the bios, because my laptop doesn't support it.

    How can I activate CSM option not by using bios (e.i. kexts or drivers or anything else (I don't know)). Or how can I solve the problem another way?

    By the way, i don't see the full screen - only a half (i see only the left part).


    I'm using OpenCore 0.6.4.

    Laptop: HP ProBook 4730s.

    Motherboard: Hewlett-Packard 167C.

    CPU: Intel Core i5 2450M.

    Graphics: Intel HD Graphics 3000.


    Please, help me.
