Rated 5 out of 5 by from Great picture!!! I won this display in a contest and can not imagine using anything else. I have tried many displays and none compare to this one. The picture is super clear and is perfect for my design work. I also think that I don't get headaches from staring at this one all day. I like the additional USB-C ports on the back. There is only one port for hooking up to the laptop. Normally that is fine but that is the only complaint that I have with this display. The port got loose over time and eventually broke :(. Other than that, hands down the best display I've ever used.

Rated 2 out of 5 by from After 4 years: screen burn ins, pinkish edges Over 4 years of usage of this display exclusively with MBP I find it extremely problematic. Disconnecting the display was often a cause for a kernel panic and sometimes it would cause a kernel panic while being connected. By now it suffers from burn ins and pinkish shades along the edges. Stand is very weak and wobbly, adjusting monitor's heigh is not pleasant at all. Warranty is very poor being only 1 year. Resolution is display's only advantage. While it lasts.

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
