LG UltraFine 4K monitor with Vega64 GPU

[wladdych]

For those, who want to use ultrafine 4k with hackintosh: I've bought used Ultrafine 4k and tried to connect it to my asus x299-based system (i have flashed titan ridge and thunderbolt 3 is working for me in catalina), but it didn't turned on and i didn't see it in system properties -> thunderbolt device tree. My videocard is Vega64, and Ultrafine 5k works fine for me. I've tried this 4k monitor with macbook pro - it works well.
