What People Are Saying

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
We regret to read that you are experiencing issues with your MacOS not recognizing the built-in camera on the LG 27" Class UltraFine™ 5K IPS LED Monitor (27" Diagonal), Model # 27MD5KA and sincerely apologize for any inconvenience. The new version 2.08 of the utility made it High-Sierra compatible and improved connectivity quality on the USB-C ports and fixed the software to the integrated camera that assisted with low performance in low-light conditions. It also brought a more precise control with volume controls from the Mac itself or attached keyboards. There are many reasons as to why the camera is not recognized and we recommend that you contact our Support Center at (800) 243-0000 and get some troubleshooting assistance from a product specialist...^IFV

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. The LG 27" Class UltraFine™ 5K IPS LED Monitor (27" Diagonal), Model # 27MD5KA has a resolution of 5120 x 2880 and features a Thunderbolt™3 port which can transmit 5K video and data while simultaneously charging a new MacBook Pro (up to 85W) over a single cable.
