The LG 32UL950-W is a very 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.
The 32UL950 has a good design. It looks very similar to the 34WK95U and 32GK850G, including the thin, curved metallic stand, and slim bezel design. The stand has a decent height adjustment and good tilt range, but it can't swivel. The display is well built, with a solid metal stand, but the rest of the monitor is made of plastic.
The stand supports the monitor well, but there is some wobble to it. The design is nearly identical to the 34WK95U.
The back is quite plain, with only minimal design features. There is a small clip on the stand for cable management.
The LG 32UL950-W delivers good overall picture quality. With SDR content, it looks excellent thanks to the great SDR peak brightness, and outstanding SDR color gamut. In HDR, it has only decent peak brightness, but it can display a wide color gamut, which is great. Unfortunately, it doesn't look as good in a dark room, due to the limited native contrast ratio, bad local dimming feature, and poor black uniformity.
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.
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.

s.RGB Picture mode: Custom (Calibrated)
Adobe RGB Picture Mode: Custom
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.
s.RGB Picture mode: Custom
Adobe RGB Picture Mode: Custom
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.
DCI P3 Picture mode: Custom (HDR)
Rec. 2020 Picture Mode: Custom (HDR)
Decent 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.
DCI P3 Picture mode: Custom (HDR)
Rec. 2020 Picture Mode: Custom (HDR)
Decent 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 good motion handling. It has a great response time, but some more serious gamers may find it too slow for fast-paced games. It has a standard 60 Hz refresh rate, and it supports FreeSync, including with NVIDIA's new FreeSync drivers. Unfortunately, it uses PWM flicker to dim the backlight, and this can be noticeable at all brightness levels, except at full brightness.
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.
The LG 32UL950 has excellent low input lag in any mode, and an excellent 32", 4k screen, that results in outstanding screen real-estate, great for multitasking or for a more immersive gaming experience. It has a decent selection of inputs including two USB-C ports, but only 1 full-size HDMI and DisplayPort connection.
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.
The LG 32UL950-W has decent additional features. It has built-in speakers and supports HDR, which is nice. There are a few options that can be adjusted from the monitor's OSD, allowing you to personalize the image to your personal preference.
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:
