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 VG2239m-LED from ViewSonic.
Display
21 inches ( 54.6 cm on the diagonal) offer sufficient space for texts in any office applications, for example. For books or documents, a portrait format layout is usually used because the reading flow decreases as the width of the text increases. For small diagonals, screens in 4:3 format have a clear advantage because they are better suited for display due to their height. In contrast, widescreen monitors are better suited for playing video games or displaying several documents side by side, for example. Depending on the application, it should be decided individually whether the aspect ratio of 1.778 : 116 is sufficient. 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 VG2239m-LED is a monitor with a ratio of 81.7 % 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 ViewSonic 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. ViewSonic promises stable color reproduction moreover within a 160 ° vertical angle. The refresh rate is horizontally seen at the VG2239m-LED 24 khz to 82 khz. Vertically, however, the image renews at a minimum rate of 50 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 ViewSonic 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 20000000 : 1 of dynamic contrast ratio for the monitor VG2239m-LED cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio.

screen design
For a possible wall mounting or comparison to the currently owned monitor at the beginning, the dimensions of the monitor without stand/feet: 30.4 cm x 51.2 cm x 5.6 cm (HxWxD)
The size of the VG2239m-LED on the desk is likely to be particularly relevant for most users. ViewSonic specifies a space requirement of 41.8 x 51.2 x 23.9 cm (HxWxD) with the included stand. If you want to place the monitor on a table or even transport it, you should expect a weight of 4.7 kg with the stand screwed in. A wall mount should be designed for at least 3.2 kg to hold the VG2239m-LED neatly and securely. Speaking of weight without a stand and thus wall or table mounts. The monitor supports a Vesa mounting. A height-adjustable stand ensures an improved ergonomic posture during use. The monitor can be moved to a maximum height of 13.5 cm. This value is always measured from the bottom edge of the screen.
Rotate, tilt and swivel
The monitor from ViewSonic 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 VG2239m-LED 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 VG2239m-LED 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. The connection of a device via display port is supported.
camera
This monitor does not have a camera.
Loudspeaker
Features
- The display/monitor supports Frame Rate Compensation.
Panel manufacturer
Many manufacturers of monitors and TVs fall back on third-party manufacturers, such as Samsung or LG, when choosing the actual display (panel). Thus, many of the monitors have the same panel and, conversely, differ only in their design, additional functionalities, the software used and, of course, the price. Two monitors from ViewSonic or another manufacturer with an identical panel do not necessarily have to have the same picture quality, but it is usually a first indicator for a purchase decision. The panel used here is originally from LG Display and has the model number LM215WF4-TLG1.
WiFi / Bluetooth
Power consumption
The average consumption was given by ViewSonic as 18 w. The maximum power consumption (peak) specified for this monitor is 22 w. In standby mode, the device consumes approximately 0.5 w. When switched off, on the other hand, the monitor consumes only 0.3 w. In ECO mode, the monitor consumes 15 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. The power grid has to supply a frequency of 50 hz to 60 hz.
Environment
The maximum height at which the monitor may be operated, according to the manufacturer's specifications, is 5 km. The maximum permissible ambient temperature is 40 °C during operation. Below a temperature of 0 °C , the monitor from ViewSonic should again not be used. The humidity must not exceed 90 percent. At least, however, 20 percent humidity. The monitor may be stored at a maximum humidity of 90 percent. The minimum humidity during storage should not fall below 5 percent. The maximum storage temperature should be according to ViewSonic 60 °C. Minimal were given by ViewSonic -25 °C. According to the manufacturer, the monitor may be stored at a maximum height of 12.192 km.
