How to Connect LG UltraFine 5K Display with Your Mac

We recommend that you use the LG UltraFine 5K Display as a second monitor with Mac mini and Mac Pro, as the display might not turn on until you boot into macOS. As a result, pre-boot features such as Boot Picker and macOS Recovery might not be available on the display.

Rated 4 out of 5 by from Perfect size and image quality I bought monitor to pair with a 2018 MacBook Pro, and I'm very pleased with monitor's image quality and size. Would recommend.

Rated 5 out of 5 by from Best of Both Worlds. Works great with MacBookPro I bought this monitor to use with my 13" MackBookPro. The graphics card in the MBP takes full advantage of this 27 inch 5K LG monitor. The images are stunning. Even after a month, I am still in awe looking at the detail and quality of what I now see. It gets better.... the monitor both charges the MBP and runs off the MBP seamlessly on just one single cord. I leave the MBP closed and plugged into the monitor. I never have to touch or open the MBP. Using an Apple wireless keyboard & mouse, it all works like a desktop. Just touching the keyboard or mouse, wakes the system up and turns on the beautiful 27" LG 5K Monitor. This is the best of both worlds - unplug the MBP and go - you have a laptop - all with just one computer. This dual purpose, the convenience of use, and the beautiful images displayed on the monitor, make the price of this quality 5K LG 27" monitor well worth it.

I can't get macOS to recognize the camera in my monitor. I have tried updating everything, I have downloaded the LG Manager and it did nothing, and this is very frustrating that such a basic function isn't working on a $1k+ monitor.

Asked by: TiredofThisMonitor
Same with mine, Camera light turns on but no video. Only purchased 5 days ago. LG is there a fix?

Why won't the screen go to sleep? It goes black but won't go to sleep.

noticeable white horizontal lines flash on and off on the right side of monitor, distortion of video. I'm using a 2013 macpro with an official apple adapter, not official mac thunderbolt 2 cord, just ordered an official cord though.

Can this monitor be used with a Linux system with Nvidia Quadro P5000 16GB graphic card?

Asked by: Don123456
All monitors work with all graphics cards. You need to check the output on your computer and see what kinds of ports are available (if you have a dedicated video card, you’ll want to look at those outputs). Then, make sure that the monitor features the same type of ports—if it doesn’t, you’ll need some sort of adapter or special cable.
