LG 32UL950-W  Monitor Review

The stand supports the monitor well, but there is some wobble to it. The design is nearly identical to the 34WK95U.

Update 01/20/2021: For consistency, we've changed the swivel adjustment from N/A to 'No'. The score remains unchanged.

Mediocre ergonomics, mainly due to the lack of swivel. It has a good height adjustment, and it can rotate to a portrait orientation, which is nice.

The back is quite plain, with only minimal design features. There is a small clip on the stand for cable management.

The borders are thin, with no significant gaps or issues. They are thin enough to be used in a multi-monitor setup.

Like many similar LG models, the LG 32UL950-W is very thin, especially when removed from the stand.

The LG 32UL950-W has good build quality. The stand is solid and well built, but the rest of the monitor is mostly plastic. Despite that, there are no obvious issues or loose parts that could break over time.

The LG 32UL950-W has a decent contrast ratio, slightly better than the 34WK95U. Unfortunately, the local dimming feature is ineffective at boosting the contrast ratio. With uniformity compensation enabled, the contrast ratio decreases to 1176:1.

The local dimming feature is bad. The 32UL950-W is edge-lit, and the local dimming isn't very effective at dimming darker areas of the screen. The local dimming algorithm also can't keep up with fast moving objects, so the zone changes can be noticeable in some circumstances. This is very similar to the Dell U3219Q and LG 34WK95U.

Update 08/17/2020: We've retested the SDR peak brightness to ensure that it's measured with local dimming enabled, as per our methodology. The results haven't changed. We also retested 7 other monitors, and some results changed.

Great peak brightness with SDR content. There is some variation in the brightness, due to the local dimming feature dimming dark areas around the smaller test patterns. With most normal content this shouldn't be as noticeable.

We measured the peak brightness with the 'Custom' Picture Mode, and Local Dimming enabled.

Update 08/17/2020: We've retested the HDR peak brightness to ensure that it's measured with local dimming enabled, as per our methodology. The results haven't changed. We also retested 7 other monitors, and some results changed.

Decent HDR peak brightness. Large bright areas can hit higher brightness levels due to the local dimming feature dimming smaller highlights.

As with SDR, we measured the peak brightness with the 'Custom' Picture Mode, and Local Dimming enabled.

Decent horizontal viewing angles. When looking at the monitor from an angle, the contrast levels remain constant, but the image appears dim, and colors lose accuracy. At narrow angles, the image remains accurate, good for two player co-op games.

Great vertical viewing angles. The contrast remains constant at all vertical angles, which is great, but the image fades, and colors become very inaccurate. This will be especially noticeable if the screen isn't at eye-level, or if you are sharing your work with someone standing beside you.

The 32UL950 has great gray uniformity. There is almost no noticeable dirty screen effect, which is great. In near-black scenes, the uniformity is almost perfect.

There is a Uniformity mode, that is supposed to improve gray uniformity. Since the monitor already has excellent gray uniformity, there is little benefit to enabling this, and it causes a decrease in native contrast.

The LG 32UL950-W has poor black uniformity. There is noticeable black light bleed along the edges of the screen. Unfortunately, the local dimming feature actually makes things worse, as the edge-lit system can only dim the columns that are far away from the test cross, and there is still noticeable bleed.

Decent accuracy out of the box. The gamma does not follow the target curve at all, which causes some scenes to appear too dark, and some scenes to appear too bright, and the color temperature is a bit warm. The color dE and white balance dE are high enough to be noticeable by most enthusiasts.

After calibration, the LG 32UL950-W has excellent accuracy. Gamma follows the target curve almost perfectly, which is great, and the color temperature is much closer to the calibration target of 6500 K. Color and white balance errors are corrected, and any remaining inaccuracies are too small to be noticed without specialized equipment.

You can download our ICC profile calibration here. This is provided for reference only and should not be used, as the calibration values vary per individual unit even for the same model due to manufacturing tolerances.

Outstanding SDR color gamut, with essentially perfect coverage of the s.RGB color space, and excellent coverage of the wider Adobe RGB color space, great for professional photo and video editing.

Excellent SDR color volume, one of the best we've measured so far. The higher native contrast allows the 32UL950 to display darker colors than the 34WK95U, especially in the Adobe RGB color space.

Update 08/17/2020: We've retested the HDR color gamut to ensure that it's measured with local dimming enabled, as per our methodology. The results have changed slightly. The DCI P3 coverage increased from 76.9% to 79.8%, and the Rec. 2020 coverage increased from 69.5% to 69.7%. The score has been adjusted accordingly. We also retested 7 other monitors, and some results changed.

Good HDR color gamut, but not as good as the LG 32UD99. The 32UL950 can display a wide color gamut, which is great for HDR movies and games.

Update 08/17/2020: We've retested the HDR color volume to ensure that it's measured with local dimming enabled, as per our methodology. The P3 color volume decreased slightly from 69.1% to 67.9%, and the Rec. 2020 color volume remains in the same ballpark, from 68.8% to 68.4%. The score has been adjusted accordingly. We also retested 7 other monitors, and some results changed.

Okay HDR color volume, slightly better than the 32UD99. It is limited by the HDR color gamut, and can't produce dark saturated colors in HDR, due to the limited contrast ratio.

There are no signs of temporary image retention on the 32UL950, even immediately after displaying our high contrast static test image for 10 minutes.

The LG 32UL950-W has outstanding gradients. There is almost no noticeable banding in any shade, which is great.

There are only extremely minor pixel errors, not enough to be noticeable under normal viewing conditions.

Good reflections handling, but it doesn't perform as well in a bright room with lots of windows.

Response Time Faster

The 32UL950 has a great response time, nearly identical to the Dell D3218HN. There is some overshoot and undershoot in some transitions, but it is relatively minor, and shouldn't be noticeable. We recommend the 'Normal' Response Time, as higher settings significantly increased the level of overdrive, causing worse overshoot with only minor performance gains.

The duplications in the motion blur photo are caused by the backlight flicker.

Unfortunately, there is PWM flicker at all brightness levels below max brightness. If you are sensitive to PWM flicker, setting the brightness to the maximum setting will stop the backlight from flickering. There is no option to adjust or remove the flicker completely.

The LG 32UL950-W has a good 60 Hz refresh rate, and it supports AMD FreeSync. It is also partially compatible with NVIDIA's Adaptive Sync mode, allowing you to use FreeSync VRR with a 10- or 20- series NVIDIA graphics card. Although this monitor isn't officially supported, it does work, as long as FreeSync is enabled in the monitor's OSD. Unfortunately, only the 'Ultimate' setting works, 'Basic' does not.

Excellent low input lag even in HDR, or when a non-native resolution is displayed. This should please most gamers, as the monitor feels responsive, even if you decide to play at a lower resolution for graphically intensive games.

The 32", 4k screen results in great screen real-estate, and is great for multitasking. The high pixel density is excellent for watching videos or gaming.

There are two USB-C Thunderbolt 3 ports, including one that can be used to daisy chain a second display, which is great. It also supports power delivery over one of the Thunderbolt 3 ports, which is great, but it is limited to 60W, which is just enough for most Macbook Pros.

There are a few additional features on the 32UL950, including built in speakers, and HDR support. From the monitor's OSD, there are a few additional modes, including:

• Black Stabilizer: Allows you to customize the contrast to improve visibility in dark scenes.
• Super Resolution+: Customize the sharpness of upscaled images.
• DFC: Adjust the screen brightness automatically according to the content on the screen.
• Uniformity: Adjusts the image to attempt to compensate for uniformity issues. Since the 32UL950 already has great uniformity, this simply reduces the contrast ratio without improving uniformity much.

The 32UL950 has the same joystick found on the majority of LG monitors. It is easy to use and provides good tactile feedback.
