Xcode is so heavy a program that my internet is unable to handle downloading it, and my free trial is over in plisteditpro.
some peeps use configurators, don't use them myself though
 
I have tried editing it through a plisteditpro in another computer, HDMI still causes a reboot
 
And colors have now an orange hue to them even though night shift isn't on.
 
Or any of the accessibility settings. It looks like this:

And for the moment the only changes were to delete lilucpu=9, -disablegfxfirmware and -igfxnohdmi. The sections you told me to enable were already enabled in the original config.plist, as well as Lilu.kext and all its plugins already installed.
 
I have forgotten, here's the Clover folder with the edited config.plist. Thank you again for your time and patience.

each line that has a # at the beginning means that line is disabled

you are disabling the ports that needs to be enabled to get your hdmi working

also try boot argument:
igfxonln=1

and possibly try:
-igfxhdmidivs
 
So am I supposed to enable or disable the lines here, or delete them completely? which ones? all of the lines that include sharps in them? what about the double sharps?
