The LG 32GN650-B is a good overall monitor from LG's UltraGear lineup and the upgraded successor to the LG 32GK650F-B. It has a 32 inch 1440p screen that provides plenty of space for multitasking or immersive gaming. Its low input lag makes gaming feel responsive, and it has fast response times, resulting in smooth motion. It also has features that gamers should appreciate, including a 165Hz refresh rate, variable refresh rate (VRR) support, and extras like on-screen display crosshairs. It uses a VA panel, so it has a great contrast ratio that produces deep blacks, which is ideal for gaming in the dark. The high contrast, however, comes at the expense of viewing angles, which make the image look washed out from the sides. It gets decently bright and handles reflections fairly well, so it's well-suited to moderately lit rooms. It also supports HDR, which is nice but doesn't get quite bright enough to deliver a satisfying HDR experience. Unfortunately, it has poor ergonomics, and there's quite a bit of wobble when at its highest elevation.

Our Verdict

7.6 Mixed Usage

The LG 32GN650-B is good for mixed usage. It's intended to be a gaming monitor, with a high refresh rate, fast response time, and low input lag, but it also performs well in other areas. Despite its disappointing ergonomics, its large screen size and 1440p resolution are great for productivity, watching media, and content creation. That said, it's not ideal for co-op gaming or sharing content with co-workers or friends since the poor viewing angles result in a washed-out image when viewed from the side. The HDR experience is also lacking as it doesn't have a wide color gamut and can't get bright enough to bring out highlights.

Pros
  • 165Hz max refresh rate.
  • Quick response time.
  • Large screen and high resolution.
Cons
  • Poor viewing angles.
  • Limited ergonomic adjustments.
7.3 Office

The LG 32GN650-B is a decent office monitor. At 32 inches, it's a good size for multitasking, allowing you to open two windows side-by-side. Unfortunately, though, it has poor ergonomics, so it may be harder to set it at your ideal viewing position. Also, since it's a VA panel, it has disappointing viewing angles, making it less ideal for sharing content with a co-worker because the image looks washed out from the side.

Pros
  • Large screen and high resolution.
  • Great gray uniformity.
Cons
  • Poor viewing angles.
  • Limited ergonomic adjustments.
8.2 Gaming

The LG 32GN650-B is a great monitor for gaming thanks to its 165Hz refresh rate and fast response time, which result in clear motion. It also has a remarkably low input lag, making gaming feel responsive, and its large screen size feels immersive. Unfortunately, its response time at 60Hz is significantly slower than at its max refresh rate. It's also less suited to bright rooms since it only has decent reflection handling and decent peak brightness.

Pros
  • 165Hz max refresh rate.
  • Quick response time.
  • Low input lag.
  • Large screen and high resolution.
Cons
  • Poor viewing angles.
  • Limited ergonomic adjustments.
7.5 Multimedia

The LG 32GN650-B is good for multimedia. Its 32 inch 1440p screen provides plenty of space to immerse yourself in a movie or video. However, it has poor viewing angles, so it's not ideal for watching with a friend since the image looks washed out from the sides. On the upside, it has a great contrast ratio, resulting in deep blacks in the dark.

Pros
  • Low input lag.
  • Large screen and high resolution.
  • Great gray uniformity.
Cons
  • Poor viewing angles.
  • Limited ergonomic adjustments.
7.6 Media Creation

The LG 32GN650-B is a good monitor for media creation. It offers a lot of space for viewing and editing media thanks to its 32 inch screen. It has an excellent color gamut, with near-perfect coverage of the sRGB color space and good coverage of the Adobe RGB color space. That said, it has poor viewing angles, so the image loses accuracy from the side, and its ergonomic adjustment options are limited.

Pros
  • Large screen and high resolution.
  • Excellent SDR color gamut.
  • Great gray uniformity.
Cons
  • Poor viewing angles.
  • Limited ergonomic adjustments.
7.2 HDR Gaming

The LG 32GN650-B is decent for HDR gaming. It has great gaming features, including a 165Hz refresh rate, fast response time, and low input lag. It also has a great contrast ratio, resulting in deep blacks, but it simply doesn't get bright enough to make highlights in HDR content pop as they should. To top it off, it doesn't have a wide color gamut for HDR.

Pros
  • 165Hz max refresh rate.
  • Quick response time.
  • Low input lag.
  • Large screen and high resolution.
Cons
  • Poor viewing angles.
  • Limited ergonomic adjustments.
  • Lacks wide color gamut.
  • Not bright enough to make HDR content pop.

The LG 32GN650-B has a flat, 32 inch panel. It has a fairly clean and simple design with a V-shaped stand and red accents to fit in with LG's gamer-oriented UltraGear lineup.

The stand isn't as thin as on the LG 32GK650F-B. It supports the monitor fairly well, except when it's at its highest elevation, where it wobbles quite a bit.

The ergonomics are sub-par. While it allows for a decent amount of height adjustment, it doesn't swivel at all, and its tilt range is somewhat limited. On the upside, it can rotate into portrait mode, but only in one direction.

The back of the monitor is simple, with a red circle similar to other UltraGear monitors. There's a cavity in the back of the stand for cable management.

Build Quality

The LG 32GN650-B feels adequately built. It's made of decent quality plastics, though the plastic piece on the stand used for cable management feels somewhat flimsy. It's similar to other UltraGear monitors, but there's a lot of wobble in the monitor at its highest elevation, where even moving the joystick causes it to shake a lot.

The LG 34GN650-B has a great contrast ratio, which is expected of a VA panel. Blacks look deep and inky, especially in a dark room. Our unit has an even higher contrast ratio than the advertised 3000:1, but keep in mind that contrast ratio can vary between units.

Decent peak brightness in SDR, although it's lower than the advertised 350 nits. It should be fine in moderately lit rooms, but it may struggle to overcome glare in very bright rooms. That said, the brightness stays consistent across different content.

We measured the monitor's SDR brightness after calibration, using the 'Gamer 1' Picture Mode with Brightness set to 'Max'.

The brightness in HDR is not bad. As with SDR, it remains consistent across different content, but it's not quite bright enough to make highlights pop.

We measured the HDR brightness using the 'Gamer 2' Picture Mode, HDR enabled, and Brightness set to 'Max'.

The LG32GN650-B has very good out-of-the-box color accuracy. There are slight inaccuracies in most colors, and the color temperature is a bit warmer than the target, resulting in a slightly reddish tint. Gamma doesn't really follow the target too closely, so darker scenes are darker than they should be and brighter scenes are a bit brighter than they should be.

After calibration, the accuracy is fantastic. Almost all inaccuracies are corrected, and any remaining inaccuracies shouldn't be noticeable. The color temperature is almost spot-on, and the gamma follows the curve almost perfectly, although really bright scenes are still a bit over-brightened.

The LG 32GN650-B has a great response time at its max 165Hz refresh rate. That said, it's not nearly as fast as many similar gaming monitors. The best overdrive setting is 'Faster' because it results in a quicker response time, but there's some overshoot, so you may notice some motion artifacts. Overall, though, fast-moving content looks smooth.
