    Hi,
    i have a Xiaomi notebook pro i5 8225u version with 8go ddr4.
    I do successfully installed macOs HighSierra with Windows 10 as dual boot on 2 separate ssds.
    On macOs everything working well, i only have some minor bugs but nothing really annoying, except that :
    i tried to plug in and use my external screen with HDMI port, but when i plug it, my laptop screen turn off and only my external screen is working. When i remove the HDMI cable, my screen is still black, I can't do anything but restart my computer. My external screen is successfully recognised in my settings, I can use my laptop on my external screen when plugged in, but i would like to use it as a second screen not as my primary one.


    Could you guys help me please, thanks.

    You can usually find your vanilla EDID in your Clover bootlog.

    I generated my bootlog file with Clover Configurator, there is noting related to vanilla in it >< . Is there any tutorial i could follow to get it ?
    Im trying to follow these instructions from worm :

    1.Get vanilla EDID

    2.Find the 21th word, (95 in my case: 00 FF FF FF FF FF FF 00 06 AF 3D 12 00 00 00 00 00 17 01 04 95 1F …)

    3.Replace it with a Apple screen’s value(get from FixEDID - MBP worked in my case,MBA not.)

    4.Create folder(with file) under /System/Library/Displays/Contents/Resources/Overrides with modified EDID.

    5.Reboot & test


    But im stuck at step 1.
    I linked my generated bootlog.txt
