Unable to get 4K @ 60Hz resolution

by Rafay   Last Updated October 17, 2018 10:12 AM

I have a Macbook Pro 2017 and an LG 27UD68-P UHD 4K IPS display. I recently purchased this DisplayPort to USB-C cable, but I'm still unable to get 4K resolution at 60 Hertz. The options for refresh rate are greyed out at 30 Hertz (NTSC).

What am I doing wrong?
