The LG 32UD59-B is a fairly large 4k monitor with decent picture quality and the ability to produce deep and fairly uniform dark scenes. Motion handling is good but the responsiveness of the monitor is limited by the standard 60Hz refresh rate. In a bright room, reflections may be distracting and the image degrades when viewed at an angle.

Our Verdict

7.4 Mixed Usage

Above average monitor for a range of usages. The high native contrast ratio and high resolution of the 32" screen result in a very versatile monitor. Unfortunately, the picture quality is only decent and degrades when viewed at an angle. The ergonomic adjustments are also limited, which makes it less useful for sharing images with friends or coworkers.

  • Deep and uniform dark scenes
  • 4k resolution is great for multiple windows
  • Solid colors are uniform
  • Image degrades when viewed from the side
7.5 Office

Good for office use. The large screen and high resolution helps with multitasking, reading, or working on spreadsheets. Unfortunately ergonomic adjustments are very limited, and the image loses accuracy when viewed at an angle so sharing images with coworkers can be more difficult. The picture quality is also only decent, and reflections are more distracting than with some other monitors.

7.8 Gaming

Very good monitor for gamers. The response time is fast, resulting in only a short trail following moving objects which is great. Unfortunately, it isn't possible to flicker the backlight to clear up the monitor further, and the responsiveness is limited by the standard 60Hz refresh rate. The input lag is low, which is great, but picture quality is only decent.

7.2 Multimedia

Decent TV for watching YouTube, movies or TV shows. Overall, picture quality is decent but when viewed in a dark room blacks appear deep and fairly uniform, which is good. The colors are also fairly accurate out of the box, which is good.

7.3 Media Creation

Above average for creating or editing media. The high resolution makes it easier to work on high-quality images or video. The image quality is decent, but the LG 32UD59-B does support a decent amount of the Adobe RGB color space and is quite accurate out of the box. When working in a dark room, dark scenes appear deep which is good.

5.8 HDR Gaming

This monitor doesn't support HDR. This is common for most monitors, as HDR is a relatively new feature for PCs. For an HDR monitor, see the Samsung CHG70.

The design of the LG 32UD59-B is very good. Compared to the 27UD68P-B, it has a matte finish on the stand and bezel this time and it looks quite nice. It has limited ergonomic options but feels quite sturdy. If you plan on mounting it, you may have some issues to access the rear-facing connections at the back.

15.7" (39.9 cm)
8.7" (22.1 cm)

The stand of the LG 32UD59 is very similar to other LG monitors, like the 27UD58-B. It is very secure and sturdy. Compared to the 27UD68P-B and the 27UD58, this monitor has a glossy finish with a matte brushed look which should help reduce smudges and fingerprints.

Height Adjustment
4.7" (11.9 cm)
Switch portrait/landscape No
Swivel Range N/A
Tilt Range -20° to 0°

Like most other LG monitors we have reviewed, the LG 32UD59-B offers limited ergonomic options, which may make it difficult to find a comfortable viewing position. It does not rotate and can only tilt backward up to 20°.

Wall Mount VESA 100x100

The back of the monitor is nearly identical to the smaller variant, the 27UD58-B. The ports on this monitor all face out so if you are planning on VESA mounting this monitor, you may have some issues with the connections. There is a bracket attached to the stand to help with cable management.

0.5" (1.3 cm)

The border of this monitor is quite thin at 0.5". There is almost no space between the edge of the bezel and the first pixels. The thin bezel makes this monitor a good choice for multi-monitor setups.

Thickness (with stand)
5.6" (14.2 cm)
Thickness (without stand)
1.8" (4.6 cm)

The stand on this monitor is attached to the VESA mounting point instead of the bottom like most other LG monitors we have reviewed. This makes the stand appear bulkier than it is. Overall, it is quite thin and sits nicely against the wall.

Build Quality

Overall, the build quality is average. Like the 27UD58-B, this monitor is entirely made of plastic, including the stand. This shouldn't be an issue with normal use though.

Picture Quality

Contrast with local dimming

Good contrast ratio for this LG monitor. With a contrast ratio of 2644:1, this monitor has some of the best contrast ratios for an LG monitor. Though still not as good as any VA TVs, the 32UD59-B blacks are deeper than on traditional IPS monitors, which is good if you are planning to use it in a darker environment.

Poor viewing angle performance, typical of VA panels. Colors remain fairly bright and accurate up to 45°, but poor black levels beyond 16°. This monitor needs to be centered in your field of view at a decent distance. If you are viewing the monitor close up, the edges will be at a different viewing angle and will appear slightly different.

Great gray uniformity for the LG 32UD59-B. Some uniformity issues can be noticed (bright edge near the left corners and some warmer vertical bands), but overall, the screen still is pretty even. Dirty screen effect is visible on some occasions, especially when there is a panning shot over a white surface, but it is not too distracting otherwise. This is great when viewing large uniform areas, such as browsing the web or watching YouTube.

Looking at the 5% gray test picture, the bright edges are a bit more evident, and are noticeable almost the full width of the monitor. Both sides are also a bit lighter than the center. Those issues are also visible on the black uniformity picture and are likely linked to the backlight bleed.

The black uniformity is decent. Backlight bleed is visible near both left corners, but the rest of the monitor is free of severe backlight bleed and is fairly even, which is good for dark multimedia content such as when watching Netflix at night. This is a much better result than on the LG 27UD58-B.

The LG 32UD59-B performs exceptionally well in the most common s.RGB color space. It covers most of the professional Adobe RGB colorspace but has some issues with whites, greens, and blues. This is good enough for typical use, but some professionals that work in the wider Adobe RGB gamut may be limited by the color gamut of this monitor.

There is no horizontal bleed when large areas of uniform color are displayed. There is only a very slight vertical bleed, not noticeable under normal usage.

Picture Quality

The reflection handling of the LG 32UD59-B is decent. The semi-gloss finish diffuses reflections on the screen, which reduces their intensity but does produce some smearing of bright objects. This should be fine for most rooms, but in a bright room, it may be an issue.

Fast pixel response time, good enough for fast moving content like video games. Most of the blur in the photo is due to 60 fps persistence; only a faint ghosting/smearing trail can be seen following the logo, which is great. 'Response Time Slow' is the most balanced overdrive setting; 'Normal' wasn't any faster overall and added noticeable overshoot.

The monitor's 60 Hz native refresh rate is decent but not great; however, its FreeSync support is very helpful when gaming. The monitor has two FreeSync ranges: Extended (40-60 Hz) and Basic (48-60 Hz); we recommend using the Extended range unless you're experiencing problems in a game. Unfortunately, even the 'Extended' range's 40-60 Hz isn't a very wide range, which can be inconvenient.

Update 01/15/2019: We have retested the 32UD59 with NVIDIA's new FreeSync drivers. Like the 27UK650, the 'Extended' mode did not work, and was constantly tearing, but 'Basic' worked great.

Great low input lag, good enough for all but the most competitive esports gamers. Most other 60 Hz monitors have similar input lag, such as the Dell U2715H, while many 144 Hz monitors have lower input lag because of their faster panel, such as the Samsung CHG70.

The LG 32UD59 has built-in speakers that get decently loud, though they sound a little muffled. The monitor also has some image processing features, such as 'Super Resolution+', which improves upscaling of lower resolutions, and 'Black Stabilizer', which changes the monitor's gamma curve to brighten or darken dark details like shadows, which can be useful for gaming.

On-Screen Display (OSD)

The LG 32UD59-b uses a small joystick to control the OSD and act as the power button, like most other LG monitors. This joystick is actually a very intuitive way to navigate the OSD, far better than the typical four button system used by most monitors.

Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The LG 32UD59-B is an above-average monitor for a range of usages, and the 4k resolution is a bonus for productivity but for the price, there may be better choices depending on your specific usage. See our recommendations for the best 4k monitors, the best 4k gaming monitors and the best 32 inch monitors.

BenQ EW3270U

The BenQ EW3270U is slightly better than the LG 32UD59-B. The BenQ EW3270U supports HDR, whereas the LG 32UD59-B has a better ergonomics that allow you to place it in a comfortable working position with ease.

Samsung U32J590/UJ59

The LG 32UD59-B is better than the Samsung UJ590. The LG has a completely flicker-free backlight, and the stand has an adjustable height. The LG is also much brighter and has two full-bandwidth HDMI 2.0 ports that support 4k @ 60Hz.

LG 32UD99-W

The LG 32UD99 is much better than the LG 32UD59-B. The two monitors have a similar design, with a nearly identical frame and bezel, just a different color. The main difference between the two is due to the different panels; the UD59 uses a VA panel whereas the UD99 uses an IPS. The UD99 is brighter, has wider viewing angles, and supports HDR.

LG 27UK650-W

These two monitors have different panel types, each with its advantages and disadvantages. The LG 32UD59-B is larger and has a VA panel with a higher contrast ratio that delivers deep blacks in a dark room. The LG 27UK650-W has an IPS panel with wider viewing angles, which is great for sharing your work. It has better ergonomics, so you can position it comfortably with ease, and it supports HDR.

LG 43UD79-B

The LG 32UD59-B is better than the LG 43UD79, unless the larger screen is really important to you. The LG 32UD59-B has better ergonomics and can be more easily adjusted to a comfortable viewing position than the 43UD79, which has very little adjustments. The LG 32UD59-B has better motion handling, as the faster refresh rate produces less motion blur. The 43UD79 has wider viewing angles, which is important for a screen this size.

LG 32GK850G-B

The LG 32UD59-B is marginally better than the LG 32GK850G. The LG 32UD59-B has a better vertical viewing angle that helps keep the image more uniform when viewed from the top like in office environments. The 32UD59-B also supports a 4k resolution which allows it to display more content on the same size screen. On the other hand, the LG 32GK850G has better ergonomics that help you place it in a comfortable position with ease. The LG 32GK850G is better for gaming as it has a lower input lag, a faster refresh rate, and a faster pixel response time that only leaves a small blur trail.

BenQ EL2870U

The LG 32UD59-B is better than the BenQ EL2870U. The LG has a larger screen, and the VA panel delivers better dark room performance. The LG also has a slightly more versatile stand, and the image remains accurate when viewed at an angle. The EL2870U supports HDR, although this doesn't add much.

LG 34UC79G-B

The LG 34UC79G-B is slightly better than the LG 32UD59-B, unless dark room performance is a priority. The 34UC79G-B has an IPS panel, which has a higher native refresh rate and much wider viewing angles, as well as lower input lag. The LG 32UD59-B has a VA type panel, which has better dark room performance but worse viewing angles. It also has a higher native resolution.

LG 27UD68

The LG 27UD68P-B is somewhat better than the LG 32UD59-B, unless your main use is in a dark room. The LG 27UD68P-B has an IPS panel, which has wider viewing angles, whereas the 32UD59-B has a VA panel which has better contrast and better black uniformity, good for dark room viewing.

Samsung CHG70

The Samsung CHG70 is better than the LG 32UD59-B. The Samsung CHG70 has better ergonomics and is easier to position to your preference, and this is great for every usage. The Samsung has a local dimming feature, better color gamut, and support for HDR. At the same time, it has much better motion handling and is packed with gaming features so you'll enjoy gaming more on the Samsung. On the other hand, the LG 32UD59-B is marginally better for office as it has more screen area and can display more detail due to the higher resolution.

Dell S3219D

The LG 32UD59-B is significantly better than the Dell S3219D. The LG has a better 4k resolution and can display more detail on your screen, and has a better out-of-the-box color accuracy. On the other hand, the Dell S3219D has a slightly higher refresh rate and marginally lower input lag, great for gaming.
