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.

Weight (with stand) : 15.7lbs (7.1 kg)

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.

Stand
LG 32UD59-B Stand picture
Width : 15.7" (40.0 cm)
Depth : 8.7" (22.0 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.

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°.

Back
LG 32UD59-B Back picture
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.

Borders
LG 32UD59-B Borders picture
Borders : 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
LG 32UD59-B Thickness picture
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.

LG 32UD59-B Build Quality picture

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.

The LG 32UD59-B monitor has a decent picture quality. The good contrast ratio paired with the better than average black uniformity results in deep dark scenes, especially when viewed in a dark environment. For an office or another well lit room then the 32UD59-B does an average job, as the SDR peak brightness could be better and the reflection and glare handling is only decent.

Gray uniformity is great and dirty screen effect is kept to a minimum and is not distracting. Viewing angle, on the other hand, is mediocre so this monitor isn't the best for people who sometimes watch from the side or share images with others. Out of the box, the 32UD59-B has very good accuracy and can display colors very well. The 32UD59-B is not HDR compatible, but still has excellent coverage of the sRGB color space which is good for editing photos.

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.

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.

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.

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.

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.
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.
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.
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.
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.
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.

"Image degrades when viewed from the side". That's definitely an issue I found but other than that I liked it. One question: My PS4 Pro doesn't enable 4K 60hz on this monitor unless I turn HDMI ULTRA HD Deep Color feature on (located under image settings below contrast). Any idea why is this happening? If this feature is turned off my PS4Pro shows 4K at 25 and 30hz as options only and it displays at 1080p maximum. It says "Check your display settings". I can select 4K RGB no problems with "HDMI ULTRA HD Deep Color" turned on though
Yes, you need to turn on this option to allow the HDMI port to accept the full HDMI 2.0 bandwidth (4k@60Hz). When not turned on, the PlayStation won't see that it can accept the full bandwidth and will fall down to a lower resolution. You can leave this option 'On' and you should not get any issues.

How does this compare to something like the new Sony 900F (I'm still waiting for the 49" to be available)? I'm a software developer and my main function will be for displaying / editing as many lines of code on the screen as possible :). As a hobby, I am a wannabe photographer and I use Photoshop / Premier often for photo / video editing. It seems like the 900F might be a better choice for software development (black uniformity, accurate color for keywords, etc). But a "PC Monitor" might be better for editing media due to its Adobe RGB coverage. Input lag doesn't concern me too much as I'm not a gamer and I rarely use the mouse while coding. I also considered the Dell P43Q, but I think you are paying for the 4 simultaneous inputs vs picture quality. I love this site and would greatly value your feedback.
The X900F would be an excellent choice as a PC monitor, as long as you are planning on sitting 7-8' away. The poor viewing angle will result in washed out colors on the sides and uniformity issues when sitting too close. For photo editing the better color gamut on the 32UD59 would be an advantage, but the X900F would still be an acceptable choice. Unfortunately we haven't reviewed the P4317Q, but you can suggest it here for us to review.

I am interested in buying a new monitor for my computer, but it seems that today's TV sets are on par with computer monitors, with a few differences such as color gamut and input lag. For the average user, would a TV with comparable response time and decent color with a larger screen for the same price be better than a monitor? Most monitor reviews seem to receive average scores, whereas a few TV sets measured above average when used as a monitor. Would it be fair to plot a TV measurements against a computer monitor measurements when comparing the two? Is there a reason that the two cannot be directly compared?

Scores for PC monitors are not calculated quite the same way as our PC Monitor rating on TVs, due to differences in testing methodology, so it is not recommended to directly compare the two scores. PC monitors take other factors into account such as ergonomics and vertical viewing angle, which we don't currently test for on TVs.

For the most part though, TVs and monitors are very similar. Depending on your needs a TV might be a better choice. A bigger screen is not necessarily good if you are going to be sitting two feet away from the TV, since you will be too close to have a good viewing angle. For example, the Sony KD43X720E is currently the best TV we have reviewed for usage as a PC monitor, but most people would find it would look best at ~6 feet.
