Note that if you're using USB-C for video, then the downstream USB ports of the LG 27UK850 can only work as USB 2.0 (480 Mbps). The second Thunderbolt 3 port of the Thunderbolt 3 device can be used to connect a USB-C cable to the LG 27UK850 for video and USB data. Connect a Thunderbolt 3 device that has two Thunderbolt 3 ports (such as a Thunderbolt 3 dock or RAID drive) to the MacBook Pro 2015 using the Apple Thunderbolt 3 to Thunderbolt 2 adapter.
There is a way to get video over USB-C to the LG 27UK850 from the MacBook Pro 2015. The charger is now in bad shape, so looking for replacement. The downstream ports will work as USB 3.0 (5Gbps) in this configuration. I have a Macbook pro Retina (late 2012) uses 60w charger.
