The LG 32GK850G-B is a decent 32 inch QHD VA LCD monitor with a very good gaming performance. The picture quality is mediocre, mainly due to the disappointing viewing angles, but it has a high native contrast ratio, so blacks look deep if you use it in a dark room. It can get bright enough to overcome glare, and because of its good reflection handling, it is suitable for a bright room. It has a very fast pixel refresh rate, a very low input lag and it supports the G-SYNC variable refresh rate implementation and should keep most gamers happy.

Our Verdict

7.4 Mixed Usage

This is a decent monitor for mixed usage. It has a large screen size, good resolution and a very low input lag that makes it very responsive to your actions. Unfortunately, the poor viewing angles do not allow you to easily share your work. Gamers will appreciate the G-SYNC feature and the fast refresh rate.

7.1 Office

This is a decent monitor for office use. It has a good size and enough resolution to display a lot of detail and allow you to multitask. It has poor viewing angles and thus is not a good choice if you work side by side with your colleagues, although the decent ergonomics somewhat counteract that. It has good reflection handling and can be placed in a bright office without issues.

8.3 Gaming

The LG 32GK850G-B is a great monitor for gaming. It has an excellent low input lag, and the screen is large with enough resolution to display most details of your favorite game. Furthermore, it supports the G-SYNC implementation of VRR which helps eliminate tearing. Its pixel response time is very fast and the decent ergonomics will allow you to place it comfortably without the need for a VESA mount.

7.1 Multimedia

The LG 32GK850G-B is a decent monitor for multimedia usage. The large screen size and good resolution allow you to display most multimedia content at native quality. The good refresh rate only leaves a small blur trail in fast-moving content and the decent ergonomics allow you to position it to your liking without too much effort. The picture quality is ok with deep blacks and a full range of colors.

See our Multimedia recommendations
7.3 Media Creation

This LG monitor is a decent monitor for media creation. The 32-inch screen and QHD resolution will allow you to display many details of your content on the screen, without the need to continuously zoom in and out. It has a low input lag that makes very responsive to your actions, good reflection handling and decent ergonomics which allow you to place it comfortably. Unfortunately, it is not suitable for professionals in the printing or publishing media as the coverage of the Adobe RGB color space is not adequate.

The design of the LG 32GK850G is very good. It has a sturdy stand and good ergonomics to allow you to position it to your liking. It comes with an illuminated circle in the back that provides a nice ambient light when placed close to a wall in a darker room. This light is independent and can work even when the monitor is turned off. It is controlled by a rotating wheel next to the monitor's control joystick. The build quality of this monitor is good and you should have no issues with it.

The stand looks elegant and supports the monitor well. If you accidentally knock the monitor, it will wobble a little.

Update 08/09/2019: There was a mistake in our swivel range scoring. The ergonomics score has increased slightly.

Decent ergonomics. The monitor can be easily positioned to your liking. The only downside is that some adjustments have a limited range. It is worth noting that the manual of the monitor sets the swivel range at -20° to 20°, but our unit had a swivel range of -15° to 15°.

Wall Mount VESA 100x100

The back of the monitor is plain. There is an illuminated circle whose color you can control even when the monitor is off.

There is minimal planning for cable management, only a clip attached to the stand pole.

0.4" (1.0 cm)

The borders of this monitor are thin and made out of plastic. There is a very thin bezel, and the screen almost touches it. There is a gap, however, between the edge of the screen and where the active pixels start. If you plan to use this monitor in a multi-monitor setup, you might find this a little annoying.

Thickness (with stand)
8.1" (20.6 cm)
Thickness (without stand)
2.2" (5.6 cm)

The LG 32GK850G-B has an average thickness when it is not hooked to its stand. When placed on its stand, it is among the thickest monitors we've measured so far, and you will not be able to push it all the way to the wall.

Build Quality

The build quality of this monitor is decent. There are no gaps where different components meet, and the entire construction, although plastic, feels robust. You should have no build quality issues with this monitor.

Contrast with local dimming

The contrast of the 32GK850G-B is good. This is expected as it is a VA panel. The good contrast ratio improves the picture quality as it makes blacks look deep in a dark room. The performance is very similar to LG 32UD59-B.

The horizontal viewing angles are bad. Even slight moves off the center and the image quality deteriorates. Black levels, brightness, and color shifts go into the 'red' all at the same time at around 25 degrees off center. This results in uniformity issues when you view the monitor from a close distance.

The vertical viewing angles are just as bad as the horizontal ones. In this case, the black level is acceptable only for very small deviations off the center. This results in an image that does not look uniform at the top and bottom edge even when you are not too close. The results are similar to other VA monitors, like the Samsung CF791.

This monitor has excellent gray uniformity, one of the best we have tested so far. Although some might notice a little clouding in the lighter shades of gray, there is almost no dirty screen effect when browsing the web. The edges look darker and this is due to the poor viewing angles.

Decent black uniformity for the LG 32GK850G-B. There is some clouding visible, and some backlight bleed around the edges and close to the corners. This is, however, one of the best scores we have measured up to date, second only to the LG 32UD59-B.

The out of the box color accuracy of this monitor is mediocre. The most accurate picture mode was the 'FPS1'. In this mode, the white balance dE was much higher than our threshold of 3 where most enthusiasts will notice the inaccuracies. The same is true for the color dE, whereas gamma tracks the target curve shape but is slightly lower and thus the image looks slightly brighter. The color temperature is colder than our target and some might notice a slight bluish tint to the image.

We used the 'Gamer 1' picture mode to calibrate the monitor. The results were excellent as all inaccuracies become almost impossible to spot. White balance dE and color dE were both diminished at values well below 1, whereas the gamma was corrected and now tracks our curve closer. Finally, the color temperature was brought almost right onto our target of 6500 K.

The LG 32GK850G-B has an excellent color gamut for everyday use as it covers almost all of the s.RBG color space. If you are a professional working in the printing or publishing industry, this monitor is not a good choice for your work, as it does not cover the wider Adobe RGB color space well. For excellent Adobe RGB coverage, check out the Acer Predator X27.

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

Picture Quality

The handling of reflections on the LG 32GK850G-B is good. Reflections are diffused by the semi-gloss finish and this reduces their intensity. So, unless the room is too bright, you should not have any issues.

The LG 32GK850G has a very fast pixel respone time. It is one for the fastest we have measured so far. We are recommending the 'Response Time Fast' overdrive setting as this is the one that gives us the best results with minimal overshooting that should not bother most people. If you see artifacts that bother you, you can set it to 'Normal' instead.
