Evening all.
I've done a fair amount of research and haven't found a solution to this dilemma.
I have a LG 27UD68 monitor and a Dell XPS 15 (9550) laptop. I want to run my laptop to the 4K monitor at 60Hz. Everything I have found online has pointed to severe issues. For instance, the Dell 3100 dock outputs DisplayPort to 50Hz and HDMI to 30Hz. So, how am I going to get 60Hz on that monitor?
