The LG UltraFine 4K Display review, which seamlessly integrates into the current lineup of Apple MacBook Airs and Pros, provides MacBook owners with a strong and adaptable display that will work well with their systems.

Key Specifications

  • Review Price: £630
  • 23.7-inch 4K 60Hz IPS LCD
  • 2 x Thunderbolt 3, 3 x USB-C
  • MacBook Pro TouchBar support
  • Height-adjustable stand

The 24MD4KL, a 4K Ultra HD 60Hz 23.7-inch IPS monitor, is the newest model in the LG UltraFine 4K Display range of Mac OS-compatible displays. It boasts exceptional brightness and complete DCI-P3 spectrum coverage right out of the box. As a result, it is strongly angled at Apple ecosystem-connected photographers and videographers.

On this LG UltraFine 4K Display review, there are two Type-C USB ports along with Thunderbolt 3. In other words, a MacBook Air, MacBook Pro, or Mac Mini may connect to the LG UltraFine 4K Display and use 85W of electricity using the Thunderbolt 3 connections.

This is especially helpful for owners of MacBook Pro models who typically must give up one of their four priceless USB-C ports for charging because it allows power and video to be handled by a single connection, allowing you to store your mains adaptor.

Using one of the Thunderbolt ports on the LG UltraFine 4K Display, you may daisy-chain another monitor if you absolutely need more 4K space for your creative work.

The LG UltraFine 4K Display review: Design and Functions

The LG UltraFine 4K Display review


As a result of Apple ceasing to sell its 27-inch Thunderbolt Displays, the LG UltraFine 4K Display appears to be the best option for Mac customers who need to work on the road.

The LG UltraFine 4K Display chooses a more muted black plastic and metal combination with a smooth, matt effect over the traditional Apple brushed metal back and polished glass finish of the earlier Thunderbolt displays. The style is subtle, almost plain.

The LG UltraFine 4K Display includes a height-adjustable stand that can be extended to raise the monitor’s chin anywhere between 8.3 cm and 19.35 cm above your desk. The LG UltraFine 4K Display can also be tilted around 5 degrees down and 20 degrees up.

It is simple to move the LG UltraFine 4K Display into the desired position because the action is secure and smooth. It can almost be moved with one hand if you’re being lazy, but that’s definitely not a good idea. There is a VESA mount available if you don’t want to utilize the included stand and would rather have this mounted to a wall.

In terms of ports, there are two Type-C USBs equipped with Thunderbolt 3 with three standard Type-C USBs. On the back right side, near to the power cord socket, they are all arranged in a row.

While the lack of HDMI and DisplayPort may not seem particularly generous, Thunderbolt 3 technology is incredibly adaptable for Mac users, and having two ports makes it simple to connect additional accessories.

You can keep your MacBook’s battery charged without using the usual mains adapter since you can pass video (4K at up to 60fps) and draw power (up to 85W) through the same Thunderbolt connection. You can now attach a Thunderbolt 3 dock as a result.

You can even change the brightness of your laptop using a MacBook Pro with a TouchBar, and the LG UltraFine 4K Display will dim or glow in response.

The two 5W powerful bass speakers of the LG UltraFine 4K Display are great for watching videos and enjoying entertainment. The speakers don’t perform as well for music, but they seem to have been calibrated so that dialogue sounds clear, sharp, and prominent. This is especially true with streamed video, such as Netflix and YouTube content in HD and 4K.

This might not be a major concern if you plan to use speakers that plug into your MacBook Air or MacBook Pro’s 3.5mm connector instead of dedicated sound hardware for your creative or entertainment setup.

The LG UltraFine 4K Display is easy to use: Set up

The LG UltraFine 4K Display could not be simpler to set up. All that was left to do was connect the MacBook Air using the included USB-C cables after I had fastened the panel to the stand and linked it to the power.

Despite being an Ultra HD display, the LG UltraFine 4K Display comes pre-configured with Full HD (1920 x 1080) resolution.

Text certainly gets smaller as you increase the resolution to its maximum (3840 x 2160), but if you’re working with something like this on your desk and are seated around a meter away from the monitor, text is still legible. Obviously, it’s best to just use your laptop’s display if you need to perform any word processing.

The LG UltraFine 4K Display has no on-screen display because there are no external controls. You must navigate to System Preferences > Display and System Preferences > Accessibility > Display, respectively, to change the brightness and contrast.

The LG Ultrafine 4k Display review: Picture Quality

In general, you do receive the 540 nits of maximum brightness that the LG UltraFine 4K Display guarantees.

I took a reading from the center of the panel using DisplayCal 3 software and an X-Rite i1 DisplayPro colorimeter. I recorded an astounding 559.98 nits with the brightness turned up to the maximum, and a black level of 0.43 nits from the same spot, adding up to a contrast ratio of 1299:1. Although it beats the 1009:1 contrast ratio of the Apple iMac 2019, it may not be the best in its class for picture and video editing.

At maximum brightness, the visual color temperature I measured was 7098K, which is significantly cooler and bluer than the ideal 6500K, which comes the closest to precisely mimicking the temperature of daylight.

Those are fantastic results, in line with what you could anticipate from a display designed for creative work. Higher out of the box coverage might be desired by photographers who operate in the larger Adobe RGB area, but if you’re really serious about buying a display for picture work, you might think about an Eizo monitor.

Should I buy?

There is no question that you should get an LG UltraFine 4K Display if you are a Mac owner looking for a high-quality display.

This monitor is not cheap, costing roughly £630, and is not the most adaptable because it lacks DisplayPort or HDMI connectors. This display is definitely targeted exclusively towards Apple users. This 4K monitor works well as a secondary display for an iMac or MacBook as well as for a Mac Mini thanks to the great color space coverage and the ability to daisy-chain with the two Thunderbolt 3 connectors.

This will please photography enthusiasts and, assuming you can get a student discount, might be a good buy for anyone about to start a photography or digital arts course too. Color accuracy, contrast, and gamut coverage might not be as sky-high as a professionally calibrated display, but they won’t be as low either.


After LG ultrafine 4k display review article, I see that an outstanding choice for MacBook Air or MacBook Pro owners who require a little bit more room for their creative endeavors.
