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.

7.6 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.

8.0 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.

  1. Update 2/17/2020: Converted to Test Bench 1.1.
  2. Update 1/22/2019: The 32UD99 was incorrectly listed as having two DisplayPort Connections, there is only one.
  3. Update 1/17/2019: The Wide color gamut result was incorrect. The 32UD99 does have a wide color gamut.
  4. Update 1/17/2019: We tested the monitor's compatibility with NVIDIA's new FreeSync driver. See our full investigation into NVIDIA's FreeSync Drivers here.

Much like the 27UK650, the 32UD99-W has a sleek and modern design with an all-white back that fits nicely into an office environment.

Width
15.7" (39.9 cm)

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.

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, but the stand doesn't swivel.

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

Update 01/07/2020: We have seen a few reports of increasing light bleed from the corners over time. Some people have seen this start even 1-2 years after receiving their unit. We haven't noticed this on ours.

Decent build quality. The entire monitor including the stand is made out of plastic.

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.
