HDR Gaming

The LG 32UD99-W is a good IPS monitor with a great 4k resolution, wide viewing angles, and an excellent low input lag. It supports FreeSync variable refresh rate technology but has very few additional gaming features, and some gamers will be disappointed by the limited 60Hz refresh rate. It supports HDR and displays a wide color gamut, but it's limited by the mediocre HDR peak brightness as it fails to bring out highlights.

Our Verdict

7.8 Mixed Usage

The LG 32UD99-W is a good monitor for most uses. It's a great office monitor thanks to its 32 inch, 4k screen, which is great for multitasking, and it has a sleek and modern style. Fast motion looks crisp thanks to the good response time, and it has an excellent low input lag. Unfortunately, some gamers will be disappointed by the 60Hz refresh rate. However, it has wide viewing angles, good for sharing your screen with others.

Pros
  • Image remains accurate at an angle.
  • Excellent low input lag.
  • Displays a wide color gamut.
Cons
  • Doesn't handle reflections well.
  • 60Hz refresh rate is limiting for gaming.
8.0 Office

The LG 32UD99-W is a great monitor for use in an office. It has a decent stand that has height and tilt adjustments, but can't swivel. The large, 32 inch screen and 4k resolution are perfect for multitasking and it has wide viewing angles if you need to share your screen. It can get bright enough to combat glare in most office environments, although its reflection handling is disappointing.

7.7 Gaming

Good for gaming. Although it's not designed to be a gaming monitor, the 32UD99-W offers an immersive gaming experience with its large size and 4k resolution. The 60Hz refresh rate might be too limiting for some serious gamers, but it has an incredibly low input lag and good response time.

7.8 Multimedia

The 32UD99-W is a very good monitor for multimedia. Fast motion looks good thanks to the good response time, and the high resolution is great for watching your favorite videos online. Unfortunately, it isn't the best monitor for dark room viewing due to the low contrast ratio and mediocre black uniformity. However, it has wide viewing angles if you want to watch videos with a friend.

8.1 Media Creation

The 32UD99-W is great for media creation. The 32 inch screen offers plenty of space to work on and the 4k resolution delivers a crisp image. Unfortunately, it doesn't handle reflections well in bright rooms, and it doesn't get bright enough to bring out highlights in HDR. However, it has an impressive gray uniformity, so solid colors on the screen will look good.

6.9 HDR Gaming

The 32UD99-W is decent for HDR gaming. It displays a wide color gamut, but can't get bright enough to make highlights pop in HDR. The 60Hz refresh rate might be too low for some gamers, but it has a low input lag and a good refresh rate.

Differences Between Sizes And Variants

We tested the 32 inch LG 32UD99-W, which is the only model available. There are other 4k monitors available from LG, some of which are listed below. Note that these are different models with different capabilities.

Model Size Native Resolution Refresh rate Notes
32UD99-W 32" 4k 60Hz FreeSync, HDR
32UD59-B 32" 4k 60Hz FreeSync
27UD68P-B 27" 4k 60Hz FreeSync

Our unit was manufactured in July 2018 and you can see the label here.

Compared To Other Monitors

Comparison picture

Left: LG 27UK650. Middle: LG 32UD99. Right: ASUS ROG Swift PG279Q.

The LG 32UD99-W is a great monitor with low input lag and wide viewing angles, and one of the best 4k monitors we've tested so far, but the added expense for the limited HDR support might not be worth it. See our recommendations for the best gaming monitors, the best monitors for MacBook Pro, and the best 32-inch monitors.

LG 32UL950-W

The LG 32UD99-W is slightly better than the LG 32UL950. Both offer very similar performance, but the 32UD99-W has a flicker-free backlight, which is great, and it has a slightly higher native contrast ratio. The 32UD99-W has a slightly better stand that is made of metal, and better build quality.

LG 32UD59-B

The LG 32UD99-W is much better than the LG 32UD59-B. The two monitors have a similar design, with a nearly identical frame and bezel, just a different color. The main difference between the two is due to the different panels; the UD59 uses a VA panel whereas the UD99 uses an IPS. The UD99 is brighter, has wider viewing angles, and supports HDR.

LG 32GK850G-B

The LG 32UD99-W is much better than the LG 32GK850G-B. The LG 32UD99 has better viewing angles due to its IPS panel and supports HDR and 4k resolution. On the other hand, the LG 32GK850G-B has a higher native contrast ratio that makes blacks look deep in a dark room. The 32G850G-B is also a better monitor for gaming since it has a faster pixel response time that only leaves a small blur trail, a faster refresh rate, and a lower input lag.

BenQ EW3270U

The LG 32UD99-W is much better than the BenQ EW3270U for most people, unless the deeper blacks of the BenQ due to the VA panel are of great importance. The LG 32UD99 has an IPS panel with significantly wider viewing angles, so you can share your work with your colleagues more easily. At the same time, the much better ergonomics allow you to position the monitor to your liking with ease.

Dell U3219Q

The LG 32UD99-W is somewhat better than the Dell U3219Q. The LG 32UD99-W is flicker-free and has better black uniformity, which is great for dark scenes. Also, the LG 32UD99-W supports FreeSync, which is great if you're a gamer. The Dell U3219Q, on the other hand, has much better ergonomics that allow you to place it comfortably with ease.

LG 27UK650-W

The LG 32UD99-W has very similar performance to the LG 27UK650-W. The LG 32UD99-W has a larger 32" screen that some people might find more comfortable to work on. The 32UD99-W also has a built-in USB hub and a USB-C port that supports power delivery and DisplayPort Alt Mode.

ASUS ROG Swift PG348Q

The LG 32UD99-W is better than the ASUS ROG PG348Q for most uses. The LG is brighter, has better gradient handling, and supports HDR. The 32UD99 also has a better dark room performance, with much better black uniformity. The PG348Q and 32UD99-W have similar overall gaming performance, but the ASUS can be overclocked to a 100Hz refresh rate when connected with DisplayPort, and it supports NVIDIA G-SYNC instead of FreeSync.

Samsung CHG70

The LG 32UD99-W is a bit better than the Samsung CHG70, depending on your use. The Dell is better suited for office use thanks to the wider viewing angles and larger, higher resolution screen. The Samsung is better suited for gaming. It has better motion handling, mainly due to the faster 144Hz refresh rate, and it has an optional black frame insertion feature to further clear up motion. The Samsung CHG70 also has better HDR support, with a wide color gamut and much better color volume.

Dell U2718Q

The LG 32UD99-W is slightly better than the Dell U2718Q. The LG has better HDR support, with a better color gamut and much better HDR color volume. The LG handles motion better, with a flicker-free backlight as well as FreeSync VRR support. The Dell, on the other hand, has a better stand that can easily be adjusted to an optimal viewing position.

Samsung C34J791/CJ791

The LG 32UD99-W is significantly better than the Samsung C34J791/CJ791 for most people in the majority of uses. The LG has better viewing angles, due to the IPS panel, better ergonomics, can get brighter, supports HDR, and has a 4k resolution. The Samsung CJ791 has a VA panel and slightly better blacks. It also has a faster refresh rate, a lower input lag, and a curve profile for those who like it.

Dell UltraSharp U2721DE

The LG 32UD99-W is much better than the Dell UltraSharp U2721DE for most people. The LG has a larger, higher-resolution screen, which is much better for multitasking, and it delivers sharper text. The LG also supports HDR and is a more versatile monitor thanks to a few dedicated gaming features. On the other hand, the Dell has much better reflection handling, making it a better choice for a bright office.

The stand is large, and the curved shape prevents you from placing larger objects directly in front of the monitor. The monitor wobbles significantly, even typing on a nearby keyboard causes the screen to shake noticeably. It's slightly better than the LG 32UL950.
