What people are saying

Rated 5 out of 5 by from Beautiful Monitor I think this monitor is well designed both from a screen quality to the design of the cable management and stand desktop mount. The only comment I have is the power supply block is huge. But I mounted that under my desk so you don't even see it.

Rated 4 out of 5 by from Best 4K Monitor to use with MacBook I use this monitor for my MacBook Pro for personal and switch for business with my work laptop (IBM). The 4K quality and resolution on the this monitor is super sharp. The only issue has been updating the software which LG requires you to download from their website. It's not straight forward but so far I have been able keep it working. Being able to plug in and turn on via USB-C for my laptops is super easy and convenient. The built in speakers are average and there is no webcam but there are 3 usb C ports on the back for added functionality. Overall the brightness and clarity make this the best monitor to get for your home setup, especially if you are an Apple / MAC user.

Rated 4 out of 5 by from Amazing Product! Love this monitor, perfect for my uses. Unfortunately was damaged (by me) and I sent it back to LG for repair. They lost the monitor in the process and could only offer me a small portion of the original price. Wish I could find another one!

Can this monitor be used in Europe without a power converter? I'm assuming this is the case because the specs say 100-240V, but I'd like to know for sure before I move.

Asked by: Lizzzzz
HI Lizzzzz. The LG 22" Class UltraFine™ 4K IPS LED Monitor (21.5" Diagonal), Model # 22MKD4KA has a power rating of 100 - 240 V~ 50/60 Hz 1.4 A, so you will not need a step-down converter to use it abroad. Depending on where in Europe you move to, you will need an adapter for the plug on the monitor's power cord to fit into the electrical sockets they use since they use different types of sockets from those used in the U.S...^IFV

I installed the LG Screen Manager today from the App store, and updated the firmware of the display. However I don't have the "screen split" tab/functionality in the LG Screen Manager. Is this expected? Is there a missing step to set this up?

Asked by: emirpprime
The LG Screen Manager has been optimized for MacOS to provide a variety of multi-screen options and should enable you to automatically divide the screen on the LG 22" Class UltraFine™ 4K IPS LED Monitor (21.5" Diagonal), Model # 22MD4KA-B into two or four frames according to your specific needs. Regrettably, we are not familiar with which app store you downloaded the software from. There should be a download link on the monitor's support page on our site. You may want to download the software from there. The U.K. site may be different from that in the U.S. and if you need assistance, please contact the Support Center in the U.K., https://www.lg.com/uk for assistance...^IFV

Does the ambient light sensor work at all? I have been unable to find any report of its usage and it does not work for me in Sierra. Can you specify a combination of Mac and MacOS where it can actually be used to automatically adjust the brightness?

Asked by: Lee3
The Ambient Light Sensor (ALS) should work fine. To find how it works, open System Preferences and select Displays. Enable "Automatically adjust brightness" and the computer will use the ambient light sensor to automatically adjust the brightness. You can also check if Mac OS is updated. The ALS operates in accordance with Mac OS and some Mac OS doesn’t support the display ALS. If all mentioned above don't work, try to place your hand on the ambient light sensor and check if your screen will turn black. If not, then the ambient light sensor might not be working. ^AC
