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 VA2445m-LED from ViewSonic.
Display
According to the manufacturer, the display measures 23 inches ( 59.9 cm on the diagonal). As already known, two monitors with different outer dimensions can have the same screen diagonal. In the case of the monitor VA2445m-LED , we find an aspect ratio of 1.778 to 116. This means that for every 116 pixels in height, 1.778 pixels in width are added. For comparison: A classic CRT monitor had an aspect ratio of 4:3. 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 76.2 % 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 1920 x 1080 px. The pixel density is 93 ppi. The pixel pitch is 0.272 mm. The continuous possible brightness specified by the manufacturer ViewSonic is 300 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 VA2445m-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 10000000 : 1 of dynamic contrast ratio for the monitor VA2445m-LED 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
For a possible wall mounting or comparison to the currently owned monitor at the beginning, the dimensions of the monitor without stand/feet: 35 cm x 57.1 cm x 5 cm (HxWxD)
The size of the monitor (stand included) is 40 x 57.1 x 21.1 cm (HxWxD). The device weighs 4.1 kg with the stand in place. The monitor VA2445m-LED without the stand weighs 3.72 kg. This weight reduction should be taken into account for wall or arm mounting, since monitor arms have a maximum load capacity. 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 ViewSonic cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. It is possible to adjust the tilt angle of the monitor VA2445m-LED according to personal preference to ensure ergonomic and comfortable viewing. 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
- 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 InnoluxTP Vision and has the model number M236HGE-L20 (Innolux)TPM236H3-HGEL02 (TP Vision).
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 0.3 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 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, 10 percent humidity.
