The 27-inch LG UltraFine 5K Display features a 5120 x 2880 resolution, a P3 color gamut, 500 cd/m2 of brightness and built-in stereo speakers, camera, and microphone. 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 Thunderbolt 3 cable (included), it provides up to 85W of charging power to your MacBook Pro with Thunderbolt 3 (USB-C) ports. The display has three downstream USB-C ports (5 Gbps) that offer additional connectivity and power to compatible devices and accessories.

USB-C power delivery

The LG UltraFine 5K Display provides up to 85W of power over USB-C and will fully power these Mac models using the included Thunderbolt 3 (USB-C) cable:

  • MacBook Pro (2016 and later)

Power isn't delivered from the display to your Mac when you connect with the Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter. If you're using this adapter, you need to also connect your Mac to power using the power supply it came with.

The LG UltraFine 5K Display provides 7.5W to each of its three downstream USB-C (5 Gbps) 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 5K Display to your Thunderbolt 3-equipped Mac, make sure that you're using the cable that came with the display. If you don't have it, you can use a Thunderbolt 3 cable capable of delivering 5A of power.
  • The LG UltraFine 5K Display doesn't support daisy-chaining of Thunderbolt 3 devices or displays. The three USB-C ports on the display provide additional connectivity to USB 3 devices only.
  • Get help with video issues if you still don't see an image when using the correct cable.
  • You can download the LG UltraFine 5K Display owner's manual and LG Screen Manager software on the LG support page. Firmware updates for the LG UltraFine display are managed using LG Screen Manager. Run it periodically to check for and install firmware updates.
  • If the LG UltraFine 5K Display doesn't power on or you continue to have issues with video displaying correctly after following the steps in the article above, contact LG to get service for your display.
