Can’t Connect LG UltraFine 5K Display to your Mac? Tips to Fix

Is Your Mac Compatible?

  • Make sure your Mac is compatible to work with the Display
  • The LG UltraFine 5K Display is compatible to work with the Mac running macOS Sierra 10.12.1 or later
  • macOS Sierra 10.12.2 or later is preferred

Apple Recommends You To

  • You should use LG UltraFine 5K Display as a second monitor with Mac mini and Mac Pro because the display might not turn on until you boot into macOS
  • Hence, pre-boot features like Boot Picker and macOS Recovery might not be available on the Display

Use the Right Cable

  • UltraFine Display can’t deliver power to your Mac if you connect with the Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter. In case, you are using this adapter, you will have to connect your Mac to power using the power supply it came with
  • It’s better to use the cable which came with the Display
  • A Thunderbolt 3 cable equipped to deliver 5A of power can also get the job done for you

If Nothing Works, Contact LG

You need to contact LG if the Display doesn’t power. Go to the LG support page to download the LG UltraFine 5K Display owner’s manual and LG Screen Manager Software for more help.
