27UK850-W not connecting as 2nd external monitor to 16 inch Macbook pro via USB-C. SneakyDuck Member. July 2020 in UltraFine Monitors. And reward benefits. LG 27UK850 USB-C not working correctly. I use the USB Type-C connection to connect my Dell XPS 15 9560 to an LG 27UK850-W monitor. The monitor and USB hub work fine, until my display dims (after inactivity or after locking my computer). When I move the mouse to wake up the display again, it disconnects.
