So, I am currently running 10.13.4 with the supplemental update installed. However, I still have a persistent problem.....
First, I have the fix for the Vega fan installed -- works fine. Also, I am using the VegaGraphicsFixup & Lilu kexts as well. Second, I am using a single display -- LG Ultrafine 5K.
The trouble I am having, is that just about every time I boot up, only half of my desktop appears --- the right half of the screen stays black (see attached picture). If I then unplug the thunderbolt cable from the back of the display, and plug it back in, I get the full desktop.......except, OSX does not see the camera or speakers built-in to the display.
I am confident that this is not a problem with my video card or display, as I also run Windows 10 off of a separate boot drive in my machine. When using Windows 10, I have never had this or any kind of display issue.
Any of you guys have any thoughts as to what is going on, and what I might try to fix it? As always, any help would be greatly appreciated.
