Today we will look at the monitor 22BK55WD from LG from the year 2017. 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
The display is sized at 22 inches ( 55.8 cm on the diagonal). While classic CRT monitors were built with a screen ratio of 4:3, this monitor has a ratio of 1.6 : 1 (width to height). In addition to the aspect ratios and the specified screen diagonal, the ratio between the monitor surface and the actual display could also be important for some enthusiasts. This ratio describes the general relationship between the non-display area and the display. In other words, approximately 81.9 % of the front surface of the monitor consists of the display, while the remaining percent consists of screen edges and does not enable image reproduction. When setting up several monitors next to each other, it is advisable to prefer models with the narrowest possible edges. The display is a TN panel. The panel has a resolution of 1680 x 1050 px. The pixel density is 90 ppi. The pixel pitch is 0.282 mm. The continuous possible brightness specified by the manufacturer LG is 250 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 22BK55WD 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 1000 : 1 , according to the manufacturer. In contrast to the static contrast ratio, the dynamic contrast ratio changes the brightness of the panel itself in addition to the difference measurement from black to white. In addition to the difference between the brightest and the darkest pixel, the backlight is thus changed. Since the brightness of the panel may not be able to be adjusted exactly to a single pixel, a so-called halo effect is possible. The value of 5000000 : 1 of dynamic contrast ratio for the monitor 22BK55WD cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio.
HDR
The monitor supports all HDR modes listed here:
screen design
The following dimensions must be planned for a free-standing stand without attached feet/stand: 33.8 cm x 50.5 cm x 5.8 cm (HxWxD)
The size of the 22BK55WD on the desk is likely to be particularly relevant for most users. LG specifies a space requirement of 38.7 x 50.5 x 25.9 cm (HxWxD) with the included stand. The device weighs 4.9 kg with the stand in place. According to LG , you can expect a weight of about 3.5 kg without the stand. A height-adjustable stand ensures an improved ergonomic posture during use. The monitor can be moved to a maximum height of 13 cm. This value is always measured from the bottom edge of the screen.
Rotate, tilt and swivel
The monitor from LG has a pivot function and can thus be rotated using the included stand. A rotation to the left is possible with up to 0 degree. To the right, the monitor can be rotated by 90 degree. The 22BK55WD can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 180 degree. Pivoting to the right is possible up to 180 degree. The monitor 22BK55WD can be tilted. The angle of inclination to the rear is 35. 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
The monitor from LG has integrated speakers, for playing sounds, music or speech. The sound is emitted via 2 speakers, which are integrated into the device. Each of the built-in speakers has a contingent of 1 w power.
Features
- Flicker Free: LG 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
- The display/monitor supports Frame Rate Compensation.
WiFi / Bluetooth
Power consumption
On average, the monitor consumes approximately 14.5 w. The maximum power consumption (peak) specified for this monitor is 16.1 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 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.
Packaging
The monitor is packaged in a cardboard box measuring 40.7 x 60.6 x 20.8 cm (height x width x depth). The box together with the monitor weighs about 6.7 kg.
