  • Which LG 4K monitor? The original LG UltraFine 4K display (21" 4096x2304) requires a USB-C input. Connect a Thunderbolt 3 device with two Thunderbolt 3 ports with an Apple Thunderbolt 3 to Thunderbolt 2 Adapter to the iMac. The new LG UltraFine 4K display (24" 3840x2160) can use USB-C or Thunderbolt input. Connect the display with a Thunderbolt 2 cable and an Apple Thunderbolt 3 to Thunderbolt 2 Adapter. Other LG displays may have a DisplayPort input. Use a Mini DisplayPort to DisplayPort cable.
