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.

Great monitor for editing pictures

By Susan
Rated 5 out of 5
Date: 2022-10-20

I purchased this monitor to edit pictures on a Mac through Lightroom- the color is excellent. The set up was easy and the ability to work with a second monitor makes the process so much easier.

Super sharp. Good stand.

Very sharp. Better color than the first LG I got. Also, better viewing angle. First LG (not a 5k) had poor viewing angle that resulted in screen vignetting if I wasn't dead on 90 degrees. This does not have that issue. The stand allows the monitor to go 7 above the top of the stand base. Nice to have the higher range. No ghosting of items on the screen. Had monitor about three weeks now. So far so good. Comes fully assembled. Just lift out of the box and turn it on.

Saved my eyes

I have been using this for 12 hours daily since Feb 2021 with a MacBook Air M1 and MS Surface Pro. Prior to this I used the 32 in 4k LG Ergo but that was causing me eyestrain. I also got the Dell 4k 2720q which is fine for the price but is also not as clear for text. The tb3 and powered ports with supplied cables eliminated any need for a dock. It has only glitched once on me but a power off and restart a couple of times fixed that fortunately. I was hesitant to spend this much due to the reports of it suddenly dying on folks but until Apple comes out with a display of their own, its really the only option. As always, B&H had the best price and service!

Must buy for people who engage with text content throughout

Best available option for Mac

I'd originally planned on buying the recently-released Apple Studio Display, but decided to pass given its price, lack of a height-adjustable stand for the base price, problematic operating system (why does a monitor need to run a version of iOS?!), mediocre webcam, etc. This display has a better warranty and appears to use the same LG panel as Apple's display, and is less expensive.

Yes expensive...but worth it!

This is quality monitor and should be considered for those desiring a 5k experience that pairs well with a Mac mini. Colors are true. I really like the ability to adjust the viewing angle and height. I'm pleased and suspect you'll be also.

Will this accept a DisplayPort video source? Or is a thunderbolt equipped host the *only* way to send video to this display? I’m confused about this.
Asked by: Nick
I did some research on this, and it will work with USB-C (DisplayPort Alternate Mode) but only at 4K resolution. I believe LG added this functionality to this specific version of the display, it's not on the other version of it, so people could connect iPad Pro's to it, because the iPad Pro does not have Thunderbolt, yet LG shows the iPad Pro working on the marketing material on their website.
