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.

LG 32GK850G Design Picture
Curved : No
Curve radius : N/A
Weight (without stand) : 15.0lbs (6.8 kg)
Weight (with stand) : 19.0lbs (8.6 kg)

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.

Stand

Width : 18.9" (48.0 cm)
Depth : 10.6" (27.0 cm)

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

6.5 Ergonomics
What it is: How much the position of the screen can be adjusted to match the viewing preference of the user.
When it matters: All usages, but especially office and gaming use.

Height Adjustment : 4.3" (11.0 cm)
Switch portrait/landscape : Yes
Swivel Range : -15° to 15°
Tilt Range : -15° to 5°

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°.

Back

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.

Borders
LG 32GK850G Borders picture
Borders : 0.4" (0.9 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
LG 32GK850G Thickness picture
Thickness (with stand) : 8.1" (20.5 cm)
Thickness (without stand) : 2.2" (5.7 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.

7.0 Build Quality
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 32GK850G Build Quality picture

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.

The picture quality of the LG 32GK850G-B is mediocre. It has a good contrast ratio and great brightness, but unfortunately, the viewing angles are poor and the picture quality deteriorates quickly once you deviate from the center axis. It can display a large number of colors in most luminance levels as it covers the s.RGB color space well and it is suitable for a bright room as it can handle reflections well. There is no support for HDR or for local dimming.

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.

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.
