The LG 32UD99 is a very good IPS monitor with wide viewing angles, excellent low input lag, and a fast response time. It supports FreeSync but has very few additional gaming features, and some gamers will be disappointed by the limited 60 Hz refresh rate. It supports HDR, but its effectiveness is limited by the lack of a wide color gamut and mediocre peak brightness.

Our Verdict

7.8 Mixed Usage

The LG 32UD99 is a great monitor for most uses. It has a decent stand that can be easily adjusted to an optimal viewing position. The 32", 4k screen is great for multitasking. Fast motion looks crisp thanks to the fast response time, and it has excellent low input lag. Some people will be disappointed by the 60 Hz refresh rate.

See our Mixed Usage recommendations
8.0 Office

The LG 32UD99 is a very good monitor for use in an office. It has a decent stand that has wide adjustments, but can't swivel. The large, 32" screen, and 4k resolution are perfect for multitasking and it has wide viewing angles. It performs well in a bright room, with very good peak brightness and good reflection handling.

See our Office recommendations
7.6 Gaming

The LG 32UD99 is a great monitor for gaming. Motion looks great thanks to the fast response time. It has excellent low input lag, and it supports AMD FreeSync over HDMI and DisplayPort. Unfortunately, some gamers might find the 60 Hz refresh rate too limiting.

See our Gaming recommendations
7.8 Multimedia

This is a very good monitor for multimedia. Fast motion looks good thanks to the fast response time, and the high resolution 4k screen is great for watching 4k videos in HDR. Unfortunately, the effects of HDR are somewhat limited due to the narrow color gamut and mediocre peak brightness. It also isn't the best monitor for dark room viewing, due to the contrast ratio and black uniformity.

See our Multimedia recommendations
8.0 Media Creation

Very good monitor for media creation. The large, 32", 4k screen is great for seeing more of your project. Colors look great thanks to the excellent SDR color gamut and excellent color volume, and although its Adobe RGB coverage isn't perfect, it is better than most monitors we have reviewed.

See our Media Creation recommendations
6.9 HDR Gaming

Decent monitor for gaming in HDR. It has a fast response time, excellent low input lag, and FreeSync support. Unfortunately, the impact of HDR is somewhat subdued due to the limited color gamut and mediocre HDR brightness.

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 is slightly better than the LG 32UL950.

Decent ergonomics. The stand allows you to adjust the height of the monitor, and it can tilt a bit. The monitor can also be adjusted from a portrait to landscape orientation. The stand doesn't swivel.

The back is a uniform glossy white finish. There is a small loop for cable management, but it isn't very effective at keeping a clean desk.

Decent black uniformity, one of the best we have seen so far on any monitor, and better than any IPS monitor we have tested. There is some flashlighting visible around the edges of the screen, and this can be distracting when viewed in a dark room.

You can download our ICC profile calibration here. We don't recommend using this profile, as the calibration values vary per individual unit, even for the same model, due to manufacturing tolerances.

It is generally recommended to use the Extreme setting, unless you experience additional tearing or other issues.

Update 01/15/2019: We retested the 32UD99 with NVIDIA's new FreeSync drivers. Under the 'Extreme' range, FreeSync performed identically to with a Radeon card. Under 'Basic', there was still excessive tearing, and FreeSync did not appear to work properly, regardless of the refresh rate.

There are a few additional features that are typically found on most LG monitors, including:

  • Super Resolution+: an upscaling feature that tries to improve upscaling quality.
  • Black Stabilizer: improves black shades without affecting white shades.

The USB-C port supports power delivery up to 60W, and the USB 3.0 ports support quick charging.

Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The LG 32UD99 is a great monitor with low input lag and wide viewing angles, and one of the best 4k monitors we've reviewed, 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
SEE PRICE
Newegg.com

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

Dell U3219Q
SEE PRICE
B&H

The LG 32UD99 is somewhat better than the Dell U3219Q. The LG 32UD99 is flicker-free and has a better black uniformity, which is great for dark scenes. Also, the LG 32UD99 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.

BenQ EW3270U
SEE PRICE
B&H

The LG 32UD99 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.

LG 32UD59-B
SEE PRICE
Newegg.com

The LG 32UD99 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 27UK650-W
SEE PRICE
B&H

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

Samsung C34J791/CJ791
SEE PRICE
B&H

The LG 32UD99 is significantly better than the Samsung 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 curve profile for those who like it.

Dell U2718Q
SEE PRICE
Newegg.com

The LG 32UD99 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.

LG 32GK850G-B
SEE PRICE
B&H

The LG 32UD99 is much better than the LG 32GK850G. 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 has a higher native contrast ratio that makes blacks look deep in a dark room. The 32G850G 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.

Samsung CHG70
SEE PRICE
B&H

The LG 32UD99 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.

ASUS ROG Swift PG348Q
SEE PRICE
Newegg.com

The LG 32UD99 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 better dark room performance, with much better black uniformity. The PG348Q and 32UD99 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.
