About the LG UltraFine 4K Display

The 21.5-inch LG UltraFine 4K Display features a 4096 × 2304 resolution, a P3 color gamut, 500 cd/m2 of brightness and built-in stereo speakers. Integration with macOS lets you control your display’s volume and brightness without the need for physical buttons on the display.
When you connect the display using a single USB-C cable (included), it provides up to 60W of charging power to your MacBook with USB-C port or MacBook Pro with Thunderbolt 3 (USB-C) ports. The display has three downstream USB-C ports (480 Mbps) that offer additional connectivity and power to compatible devices and accessories.

System requirements and compatible Mac models

The LG UltraFine 4K Display requires a Mac with one or more USB-C ports, running macOS Sierra 10.12.1 or later. (macOS Sierra 10.12.2 or later is recommended.)
You can use the LG UltraFine 4K Display with these Mac models:
4096 × 2304 60Hz MacBook (Retina, 12-inch, Early 2016) MacBook Pro (15-inch, 2016) MacBook Pro (13-inch, 2016, Four Thunderbolt 3 Ports) MacBook Pro (13-inch, 2016, Two Thunderbolt 3 Ports) 4096 x 2304 48Hz
MacBook (Retina, 12-inch, Early 2015)
A Mac with built-in USB-C or Thunderbolt 3 (USB-C) ports is required; the display isn’t compatible with Mac models that use Thunderbolt 2.

USB-C power delivery

The LG UltraFine 4K Display provides up to 60W of power over USB-C and can fully power these Mac models using the included USB-C cable:
MacBook Pro (13-inch, 2016, Four Thunderbolt 3 Ports)
MacBook Pro (13-inch, 2016, Two Thunderbolt 3 Ports)
MacBook (Retina, 12-inch, Early 2015) and later
The UltraFine 4K won’t fully power a MacBook Pro (15-inch, 2016), which requires 85W. If you try to charge your 15-inch MacBook Pro through the display, your notebook’s battery will be utilized as well. To fully power your MacBook Pro and charge its battery, connect your 15-inch MacBook Pro to its Apple 87W USB-C power adapter when you use it with the UltraFine 4K.
The LG UltraFine 4K Display provides 7.5W to each of its three downstream USB-C (480 Mbps) ports. To charge Apple Lightning-based devices and accessories—such as iPhone, iPad, AirPods, Magic Keyboard, Magic Trackpad 2, and Magic Mouse 2—you can use the Apple USB-C to Lightning Cable or a combination of the Apple USB-C to USB Adapter and the Apple Lightning to USB Cable.

If you have issues connecting the display

If you don’t see an image after connecting the LG UltraFine 4K Display to your Mac, make sure that you’re using the cable that came with the display. If you don’t have it, you can use a USB-C 3.1 cable such as the Belkin 3.1 USB-C to USB-C Cable.
