Display, power consumption, dimensions, technologies used, connections, certifications, comfort features. All these keywords can be relevant for a purchase decision, but an exact comparison is often difficult. For this reason, we will summarize as many of the mentioned specifications as possible in an understandable form in the course of this article. Let's start with the most important component of the 22M38H from LG.
Display
Let's start with the size of the actual display. This is given in inches and measures the screen diagonal of the display. The monitor 22M38H has a display size of 21 inches ( 54.6 cm on the diagonal). It should be noted, however, that displays in this category can have different dimensions, since square monitors, for example, can have the same diagonal as a widescreen monitor. While classic CRT monitors were built with a screen ratio of 4:3, this monitor has a ratio of 1.778 : 1 (width to height). In addition to the aspect ratios and the specified screen diagonal, some enthusiasts may also be interested in the ratio between the monitor area and the actual display. This refers to the general ratio between the non-display area and the display. In other words, approximately 79.6 % of the front surface of the monitor consists of the display, while the rest is made up of screen edges and cannot display an image. When arranging several monitors next to each other, it is advisable to choose models with the narrowest possible edges. 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 22M38H 30 khz to 83 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.
HDR
The monitor supports all HDR modes listed here:
screen design
Without the stand, the monitor comes with a width of 50.8 cm , a height of 31.5 cm and about 5.6 cm.
The size of the 22M38H on the desk is likely to be particularly relevant for most users. LG specifies a space requirement of 38.6 x 50.8 x 18.6 cm (HxWxD) with the included stand. The device weighs 2.4 kg with the stand in place.
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. The monitor 22M38H can be tilted. 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.
WiFi / Bluetooth
Power consumption
The average consumption figure for 22M38H is 18 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 1.2 amps specified. The power grid has to supply a frequency of 50 hz to 60 hz.
Environment
During operation, the ambient temperature must not exceed 40 °C , to ensure full functionality. 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.
