What People Are Saying

Rated 4 out of 5 by from Needs more connections As a regular user: Colors are great, brightness is great, the feeling and size is good. My only complaints would be that it only has USB-C ports in the back, would like to have seen ethernet and a few normal USB-ports in the back. Pricetag is a bit too high, but it is 5K. The colorscheme is black which looks funky with a macbook that is silver. Unless I guess you go space gray and get the new black keyboard/ apple mouse (if you like to use everything Apple). Extremely easy to setup, pretty much packed in the box. I wish the build quality was even more robust, (like apples older monitors).

Rated 5 out of 5 by from I'm pleased with my purchase. After I received my 2017 MacBook Pro, I had to buy a screen compatible with Thunderbolt 3, so I could have my screen at eye level and my keyboard at the appropriate height. The screen works well and allows me to have several files open at once. The visual display is outstanding.

Rated 4 out of 5 by from Good Display But with Shifted Colours All great, but colors on my MacBook Pro 2017 are slightly shifted to green (and there's nothing I can do about it). For that price it's annoying.

Rated 5 out of 5 by from Fantastic Display I have been running this monitor for about a month now and absolutely love it. I am running it with a MacBook Pro and was a breeze to set up, and it has performed flawlessly.

Rated 5 out of 5 by from Excellent customer service I ordered this 5K monitor from Apple Store in Asia. It works perfect with my MacPro. However, the package came with a UK type power cord. I have contacted Apple Store support asking if I can order a replacement US type power cord, the answer is no. I then drop an email to LG support asked the same. The next morning, I received a phone call from LG support, and offered to ship me a replacement US type US power cord free of charge. Very efficient and excellent customer service.

Rated 4 out of 5 by from Great Display I was a little concern when I purchased this monitor because of all the bad reviews, but I have seen them at the Apple store and was always amazing with the screen. The price is a little steep so I decided to buy used. After some research I was aware the issue with the shielding was resolved in February of 2017 so I look for monitors that were manufactured for that date going forward. Mine has a date of October of 2017 and the box show a square which is also another indicator that this is a monitor with the shielding issue fixed. So far I have had no issues with the ones reported on the earlier reviews. No Wi-Fi issue, no missing mouse pointer, and always wakes up from a sleep and it hasn't report my MBP. To my surprises, I have Windows Laptop Gaming Legion Y720 that has a USB-C connector and was able to use the monitor at 5K resolution. So far happy with the monitor, only wish it had more than just one usb-c for video input.

Rated 4 out of 5 by from Outstanding Resolution The display is beautiful. Super sharp and crisp. The management software works great as well. I was concerned that 27” wouldn’t be enough space but it works just fine. My only criticism is the number of input ports. HDMI, and USB-3 would be nice.

Will this screen work in portrait format. Since I am a photographer and I have clients asking for book and magazine covers, can it swivel? will it give the same quality as if it is in landscape mode?

Asked by: Gerald Cummins
The version of the LG 27" Class UltraFine™ 5K IPS LED Monitor (27" Diagonal), Model # 27MD5KA that is marketed and sold in the U.S. is not designed to work in portrait format. It has a convenient height/tilt adjustment, but if you need this to function in portrait format, you may need software that allows you to do that. Some Windows Operating Systems allow you to right-click the desktop and select 'Screen Resolution', then navigate to 'Orientation'. By clicking on the drop-down menu you'll find options for Landscape, Portrait, Landscape (flipped) and Portrait (flipped)...^IFV

I am curious if it would be possible to have the video display work through connecting to the thunderport 3 port on the Lacie 6Big external drive? I have a Thunderport 3 dock that allows 5K pass-through, no USB-C ports on the monitor.

Asked by: lifestar
In order for you to get a display on the monitor, it should be a straight connection from the computer going to the monitor like thunderbolt 3.0 to thunderbolt 3.0. Its not guaranteed to get a video in that setup. For additional assistance, give us a call at 1-800-243-0000 or via our Live Chat services at ^AC

How do you get the flashing to stop, it's really annoying.  It only happens once in a while but it must stop!!!!

Asked by: MacUser1972
Many *many* Macs on Sierra have a problem with external monitors flashing, and/or going to black for a fraction of a second to multiple seconds. I encountered it on my brand new Macbook Pro 2016 15" , with both HDMI and DVI. For me, uninstalling SnapZPro seems to have been the solution.

i was confused by the apple store sevicer to use this for an mac air. so do i have any solution? or is there any way to change the output thunderbolt3 into HDIM without any influnse of the display?

Asked by: tq00i8e
The MacBook Air is not supported on a 27" display, because the MBA doesn't have the resolution support. Native resolution for an Early 2015 MBA would be 1440x900, for external display support it can handle a 3840x2160 which would be 4k.This 5k display is 5120x2880. So MBA is NOT compatible.
