Rated 5 out of 5 by from Great monitor Bought this to go along with my Macbook Pro, seem less integration.

Rated 5 out of 5 by from An Excellent Display The picture quality is amazing. And the sound from the built in speakers is crisp and clear and loud. USB-C makes connections easy and fast. No down sides. I highly recommend this product!

Rated 5 out of 5 by from Great and Beautiful monitor. I use it with the new MacBook Pro mid 2018, but I power this with the eGPU from Blackmagic Design. Works like a charm. No fuss setup.

Rated 5 out of 5 by from Seamless integration with MacBook Pro I have been using this display for ~4 weeks with a 2016 fully optioned, 13" MacBook pro. The resolution is stunning and the integration seamless (out of the box it just worked / no configuration required or messing about to get it working). The audio, camera etc all works with no problems. The only downside is that the audio quality isn't that great, which doesn't matter to me as I use high quality external speaker.

Rated 5 out of 5 by from Matches the iMac Pro Exactly This monitor is an excellent addition to an 27" iMac or iMac Pro. It allows you to adjust the height to match and the colors are spot on. Having one thunderbolt cable connection is great, too.

Rated 3 out of 5 by from Great, but needs some options Like the size and love the resolution, but the overall brightness is something i wish i could adjust.
Date published: 2018-06-29
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.

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.

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 www.lg.com/us/support/chat-and-email-information. ^AC
