Thunderbolt 3

Thunderbolt 3 is a hardware interface that utilizes the reversible USB Type-C connector. Doubling the speed of its predecessor, Thunderbolt 3 features a maximum throughput of 40 Gb/s when used with compatible devices. The connector also transmits data via USB 3.1 at up to 10 Gb/s, and dual-bandwidth DisplayPort 1.2 allows you to connect up to two 4K displays simultaneously. Additionally, you can daisy chain up to six devices from a single Thunderbolt 3 port.

Power Pass-Through

For less cable clutter, the Thunderbolt 3 port also supports up to 94W of power delivery, so you can simultaneously power your MacBook.

macOS Integration

When connected to a Mac, this monitor lets users adjust display settings such as brightness and volume without having to use its hardware buttons.

Built-In Camera and Speakers

Thanks to a built-in camera and speakers, this display offers users video-chatting capabilities right out of the box.

LG 27MD5KL-B Reviews

Crisp text and single cable connection

By JayPaul
Rated 5 out of 5
Date: 2022-05-13

I've been using this for about 2 years. The 5k resolution displays crisp text which is easy on the eyes while coding all day. Just a single Thunderbolt cable connects the monitor to the MacBook both charging the MacBook and acting as a USB hub.

Great monitor for Mac OS

[This review was collected as part of a promotion.] This LG monitor has completed my Mac M1 Max system spectacularly. It works flawlessly with my laptop to expand my desktop, and unlike the Dell monitor it replaces, it's completely functional with the Mac system. That means that the keyboard now controls volume, brightness and it charges the laptop. When I close the laptop, the LG monitor becomes my desktop seamlessly. If you're hesitating, don't. It looks amazing and works great.

[This review was collected as part of a promotion.] I'm a full-time graphic designer and have been using this as my second display. The resolution and quality of the monitor are amazing, and it's super easy to set up. I'd recommend this to anyone, especially creative professionals and gamers like myself who want the best display quality. Camera quality and audio quality are also superb!

Awesome display!

[This review was collected as part of a promotion.] I went from a 17” laptop to a 13” for work and was worried about the size difference, so I purchased this monitor. I absolutely love it!!! Great picture quality.

Works as advertised.

[This review was collected as part of a promotion.] I had misgivings about buying this monitor based on things I had heard on tech podcasts, but I am happy to say that I have noticed none of the shortcomings that the podcasters had complained about. It is a really good monitor for the money and works right out of the box with my brand new M1 Pro MacBook Pro.

6th Gen iPad Mini

This monitor CANNOT be connected to 6th gen iPad Mini. I was under the assumption that it would and thus purchased two monitors. What a complete waste of my hard earned money!

Excellent picture quality, buggy, bad support

By Gab2022

[This review was collected as part of a promotion.] Really gorgeous picture quality and color rendering. Low cost for what it is. Even though the screen is plastic it is so sharp - almost as much as glass. It is buggy in that sometimes half the display is on the wrong side. Sometimes several re-plugs or power cycles are required to get it to be on the right side (applies to 5K modes only). 4K modes look nice and don't have this issue. Tried to get an *.inf file for the monitor from the support folks and they were completely clueless. Monitor lacks reasonable controls (color modes, brightness, sharpness, power button etc....) Monitor lacks support for refresh rates other than 60Hz so playing cinematic content can be jittery.
