Just got a LG 43' 4k monitor. (LGUD79-B)
My tower has 4 OS installed, Mojave, High Sierra, Windows 10, and Ubuntu. GPU is Gigabyte Vega 64 OC
Mojave/Win/Ubuntu all have 4k 60hz as the default resolution. High Sierra defaults to 1080p 30hz. It shows 2160p but all resolutions cant go higher than 30hz. When I was plugged in to a 27" 4k Dell Ultrasharp and a 75" Vizio TV, it could do 4k 60hz on both.
Anyone know how to fix this?
