The LG 32UL950-W is a good 32" IPS monitor with great screen real estate thanks to the 4k resolution. It has wide viewing angles, which is great but doesn't look as good in a dark room, due to the limited native contrast ratio and poor black uniformity. It supports HDR and can display a wide color gamut, but the local dimming feature is bad. Gamers will appreciate the low input lag and FreeSync support, and it does work with NVIDIA's new Adaptive Sync driver.

Our Verdict

7.7 Mixed Usage

The LG 32UL950-W is a good monitor for most uses. The stand can't swivel, but it has good viewing angles, great SDR peak brightness, and good reflections handling. It has low input lag in any mode, which is great, and a fast response time. It also supports FreeSync, great for gamers.

Pros
  • Image remains accurate when viewed at an angle
  • Good for gaming, with FreeSync support and low input lag
  • Great screen real estate
Cons
  • Poor dark room performance
  • PWM flicker in the backlight
7.9 Office

The LG 32UL950-W is a good monitor for office use thanks to the large, high resolution screen with wide viewing angles that is great for multitasking. It can also daisy-chain a second monitor with the Thunderbolt 3 connection, and keep your Macbook charged with a single cable between the computer and screen.

7.4 Gaming

The LG 32UL950-W is a decent monitor for gaming. The large, high resolution screen delivers a more immersive gaming experience, and it has low input lag for an immersive experience. It has excellent low input lag, and it supports FreeSync. Unfortunately, it isn't as well suited for late night gaming, due to the limited native contrast ratio and poor black uniformity.

7.7 Multimedia

The LG 32UL950-W is good for multimedia. The 32", 4k screen is great for watching the latest 4k UHD movies, and it supports HDR, which is nice. It has wide viewing angles, great for sharing the latest YouTube trends with your friends. Unfortunately, it isn't great for watching movies in a dark room, due to the limited native contrast and poor black uniformity.

7.9 Media Creation

The LG 32UL950-W is a good monitor for media creation. The high resolution screen allows you to see more of what you are working on. It has an outstanding SDR color gamut, including great coverage of the wider Adobe RGB color space, great for professional print and video editing.

6.8 HDR Gaming

The LG 32UL950-W is an okay monitor for HDR gaming. It has excellent low input lag for a more responsive gaming experience, and a fast response time that produces only a small blur trail behind fast-moving objects. Unfortunately, it has a limited native contrast ratio, and can't get bright enough in HDR to perfectly display the creator's intent in some games.

Build Quality

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.

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.

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.

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.

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.

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.

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.

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.

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.
