This monitor is marketed towards Mac computers and only has USB-C inputs, which might be an issue for some PC users. This monitor doesn't have any controls, either, and no on-screen display, which is a bit strange.
Our Verdict
The LG UltraFine 4k 23.7 is a decent monitor for most uses. It's best suited for office use, with wide viewing angles, a high-resolution screen, and excellent uniformity. It isn't as well-suited for gaming, due to the simple 60Hz refresh rate and lack of advanced gaming features.
- Great peak brightness.
- Image remains accurate when viewed at an angle.
- Strange backlight flicker, which causes noticeable duplications.
- No HDMI or DisplayPort connections.
This is a very good monitor for office use. The 24", 4k screen delivers great screen real-estate and has wide viewing angles and excellent gray uniformity. The stand has bad ergonomics, though; it can't swivel, and can't rotate to portrait orientation.
Decent monitor for gaming. It has a fast response time, but the strange backlight flicker causes noticeable duplications. Unfortunately, it has a simple 60Hz refresh rate and doesn't support any advanced gaming features, like FreeSync.
This is a decent choice for multimedia. The 4k resolution is great for watching the latest 4k movies, and it has wide viewing angles and great peak brightness. Unfortunately, it doesn't look quite as good in a dark room, and the strange backlight flicker causes noticeable duplications in motion.
This is a decent monitor for media creation. The 24", 4k screen is great and allows you to see more of your work at once. It also has very good viewing angles, low input lag, and a fast response time. Unfortunately, the stand has bad ergonomics, so it might be difficult to place in an ideal viewing position.
This monitor doesn't support HDR. For a good 4k gaming monitor with HDR, check out the LG 27UK650.

We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
