:
FreeSync

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.

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

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.

What it is: How well built and sturdy the monitor is, and how good the materials used to build it are.
When it matters: All usages.
Score components: Subjectively assigned
LG 32UL950 Build Quality picture

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 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.

6.5 Contrast
What it is: Brightness difference between white and black. This is the main component of picture quality.
When it matters: Always, but especially when watching dark scenes.
Score components:

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.

1.5 Local Dimming
What it is: The lights behind the LCD layer adapt to the picture displayed, improving the contrast ratio.
When it matters: Dark scenes viewed in a dark room.
Score components: Subjectively assigned
Local Dimming
What it is: Whether it has a feature that controls the LEDs behind the LCD layer, to match the picture and darkens the dark portion of it.
When it matters: On LED TVs only. Dark scenes viewed in a dark room.
:
Yes
Backlight
What it is: Configuration of the lights of the backlight.
When it matters: Effectiveness of the local dimming.
Good value: Full-array/direct lighting is better for local dimming. As for the uniformity of the screen, it depends on the implementation. Some edge-lit monitors have more uniform blacks than some full-array monitors.
:
Edge

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.

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.

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.

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

7.5

Motion

Score components:

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.

8.2 Motion Blur
What it is: The performance of the pixel response time. Poor response time causes trails to follow moving objects. Response time is one of a few sources of motion blur.
When it matters: When there's fast movement on screen, such as during video games and sports.

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.
