Today we will look at the monitor 22MK400A from LG from the year 2018. Within this article, we will first take a closer look at the most important feature of a monitor -the display-, then the design, and in the next section we will go into the features of the monitor. Of course, power consumption, certifications, connectivity and other important details will also be considered.
Display
Videos and/or other applications can be displayed on the monitor's 21 inches ( 54.6 cm on the diagonal). The size specification of a monitor refers to the screen diagonal, which is usually specified in inches. It is only comparable to a limited extent for different formats. For example, a conventional 4:3 monitor with the same screen diagonal has 6% less width, but 13% more height and a total of 7% more surface area than a monitor in 16:10 format. Despite the difference in working area, wider monitors are better suited for consuming games or current movies, for example. It is also easier to display several documents simultaneously on widescreen monitors. So, it depends on the current use case whether the aspect ratio of 1.778 : 1 makes sense for the intended use case. If you want to pay attention to special aesthetics or simply want to place several monitors next to each other, you should pay attention to the ratio between display and non-display. The 22MK400A is a monitor with a ratio of 81.8 % between usable and non-usable front surface. The display is a TN panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 102 ppi. The pixel pitch is 0.248 mm. The continuous possible brightness specified by the manufacturer LG is 200 nt. The panel is illuminated by W-LED. The built-in panel ensures stable color reproduction of the image, even at deviating viewing angles, by means of its 170 ° (horizontal) viewing angle. LG promises stable color reproduction moreover within a 160 ° vertical angle. The refresh rate is horizontally seen at the 22MK400A 30 khz to 85 khz. Vertically, however, the image renews at a minimum rate of 56 hz up to 75 hz. The minimum response time of the monitor is ms. The display panel is Anti-glare/Matte (3H).
Color space
The panel has a bit depth of 8 per color channel, but what does that mean? The number of bits determines how many colors can be encoded for the individual pixels of the display. For an 8-bit panel, for example, this is 256 different colors (2^8 = 256). However, since we usually display three different colors per pixel at the same time, in theory about 16 million (256^3) different colors are possible by mixing the three pixels. A 10-bit panel could even display a billion colors. According to the manufacturer, the coverage of the NTSC 1953 color space is 72 %.
Contrast ratio
Contrast ratio is a common measurement used to represent the maximum relative differences in brightness between black and white. It describes the ability of a screen or projector to produce a high-contrast image and is the quotient of the maximum and minimum displayable luminance. The higher the values are away from each other, the stronger the quantitatively seen difference between black and white is set up, which in turn results in an improved image quality. This monitor from LG has a static contrast ratio of 600 : 1 , according to the manufacturer.

The monitor supports all HDR modes listed here:
screen design
LG Specifies the following dimensions for the monitor 22MK400A without stand/feet: 30.5 cm x 50.9 cm x 3.8 cm (HxWxD)
If you want to place the monitor described here on the desk without a wall mount, you should allow for 39.5 x 50.9 x 18.1 cm (HxWxD) of space. The device weighs 2.8 kg with the stand in place. A wall mount should be designed for at least 2.5 kg to hold the 22MK400A neatly and securely. Speaking of weight without a stand and thus wall or table mounts. The monitor supports a Vesa mounting.
Rotate, tilt and swivel
The monitor from LG cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. Thanks to the tilt function of the 22MK400A monitor, the screen position can be flexibly adjusted to minimize dazzling light sources and ensure optimum visibility. The angle of inclination to the rear is 20. The monitor can be tilted forward by 5 degree.
Ports
The monitor can be connected via 1 VGA ports.
camera
This monitor does not have a camera.
Loudspeaker
Features
- Flicker Free: LG 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
- AMD FreeSync: By dynamically synchronizing the refresh rate of the 22MK400A with the frame rate, AMD FreeSync minimizes judder and ensures smooth and enjoyable gameplay.
- The display/monitor supports Frame Rate Compensation.
The monitor from LG supports the reduction of artifacts within dark image areas, which are caused by compression of the played video files, for example. Depending on the manufacturer, this technology is called Black Boost, Dark Boost, Black Stabilizer, Black Equalizer or Black Enhancement.
WiFi / Bluetooth
Power consumption
On average, the monitor consumes approximately 19.7 w. The maximum power consumption (peak) specified for this monitor is 29 w. In standby mode, the device consumes approximately 0.3 w. When switched off, on the other hand, the monitor consumes only 0.3 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. There are 1.3 amps specified. The power grid has to supply a frequency of 50 hz to 60 hz.
Environment
The maximum permissible ambient temperature is 40 °C during operation. Below a temperature of 0 °C , the monitor from LG should again not be used. The humidity must not exceed 80 percent. At least, however, 10 percent humidity. The monitor may be stored at a maximum humidity of 85 percent. The minimum humidity during storage should not fall below 5 percent. The maximum storage temperature should be according to LG 60 °C. Minimal were given by LG -20 °C.
Packaging
The monitor is packaged in a cardboard box measuring 36.5 x 64 x 12.4 cm (height x width x depth). The box together with the monitor weighs about 3.5 kg.
