Compared To Other Monitors
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.
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.
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.
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.
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.

Test Results
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.
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.
The 32UD99-W has thin borders that are good if you plan on mounting it in a multimonitor setup.
Like other LG monitors, the monitor itself is quite thin, but it gets much thicker with the stand attached.
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.
Decent contrast ratio, but it's one of the best for an IPS panel that we've seen so far.
There's no local dimming feature. The video above is provided for reference only.
Very good SDR brightness. The LG 32UD99-W maintains consistent brightness across all scenes. This is almost the same as the LG 27UK650.
Mediocre HDR peak brightness. It doesn't get bright enough to bring out highlights and make colors pop, and it doesn't remain consistent when different types of content flash across the screen.
As is the case with most IPS panel monitors, the 32UD99-W has good horizontal viewing angles. This is good if you need to share your screen with coworkers or friends.
The 32UD99-W has alright vertical viewing angles. The screen may appear darker at the edges if you sit close to it, but this shouldn't be a problem for most people.
Impressive gray uniformity. There's almost no visible dirty screen effect in the center, which is great for browsing the web or playing sports games. The edges of the screen are a bit darker than the rest of the screen, but this shouldn't bother most people.
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.
Mediocre black uniformity. There's visible clouding throughout. This is most noticeable when viewed in the dark.
Okay out-of-box color accuracy. Most of the colors will be inaccurate, but the color temperature is somewhat close to the 6500K target. That gamma curve doesn't follow the target very well, so most scenes will appear brighter than intended.
Excellent accuracy after calibration. Color accuracy is nearly perfect and the gamma follows the target almost perfectly. Also, the color temperature is extremely close to the 6500K target.
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.
Excellent SDR color gamut. It has near-perfect coverage of the standard sRGB color gamut. Photo editors will be happy with the great coverage of the Adobe RGB color space used in photo editing.
Excellent SDR color volume. The LG 32UD99-W displays most colors well, but can't display very bright blues or very dark colors, which are both normal for an IPS monitor.
Good HDR color gamut. Great coverage of the more common DCI P3 color gamut, but the wider Rec. 2020 coverage is only decent, but it still has a wide color gamut. The Samsung CHG70 has a wider color gamut.
Decent HDR color volume. The color volume is limited by low contrast ratio, as it can't produce dark colors.
As with most VA panels, there are no issues with temporary image retention or permanent burn-in.
Outstanding gradient performance. There's some banding in the darker shades, although most people won't notice this under normal circumstances.
There's no visible sign of color bleed on the 32UD99-W.
Disappointing reflection handling. The matte finish struggles a bit to handle light even in average-lit rooms, and the reflections might be too distracting in bright rooms.
Text is exceptionally clear on the 32UD99-W. It isn't necessary to enable ClearType, but if you do, text is extremely sharp, as seen on the top photo.

Since the max refresh rate is 60Hz, the recommended Overdrive setting is once again 'Normal', although there's some overshoot in most transitions.
The 32UD99-W is flicker-free at all backlight settings, which helps reduce eye strain.
There's no black frame insertion feature to help reduce motion blur.
Alright refresh rate. The native refresh rate of 60Hz can go as low as 40Hz using FreeSync VRR technology, which can be used over DisplayPort or HDMI.
Excellent low input lag on the 32UD99-W, and it only slightly increases with VRR enabled, which is great.
The LG 32UD99-W has an excellent 4k resolution and large 32 inch screen. This is great for multitasking or for a more immersive gaming experience.
There's a USB-C port that supports DisplayPort Alt Mode, which allows you to display the image from a compatible device on the screen and at the same time charge the connected device with only one cable.
The 32UD99-W has integrated speakers, and it supports HDR10. The included LG Screen Split 2.0 software can be used to simulate multiple virtual screens on the display or to enable picture-in-picture.
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.
