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 VX4380-4K from ViewSonic.
Display
The monitor belongs to the device class 42 inches ( 1.08 m on the diagonal). As already mentioned or known, monitors have a certain number of pixels in height and width. In most cases, this is not a 1:1 ratio, which is also the case with the monitor from ViewSonic. This monitor has an aspect ratio of 1.778 : 116. This means that every 1.778 pixels in width 116 pixels in height are added. In addition to the aspect ratios and the specified screen diagonal, some enthusiasts may also be interested in the ratio between the monitor surface and the actual display. This ratio describes the general relationship between non-display and display. In other words, approximately 91.8 % of the front surface of the monitor consists of the display, while the rest consists of screen edges and cannot display an image. When setting up several monitors next to each other, it is advisable to give preference to models with the narrowest possible edges. The display is a IPS panel. The panel has a resolution of 3840 x 2160 px. The pixel density is 103 ppi. The pixel pitch is 0.245 mm. The continuous possible brightness specified by the manufacturer ViewSonic is 350 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 178 ° (horizontal) viewing angle. ViewSonic promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the VX4380-4K 24 khz to 160 khz. Vertically, however, the image renews at a minimum rate of 50 hz up to 75 hz. The average response time of the monitor is about ms. The display panel is Anti-glare/Matte (3H).
Color space
The panel has a bit depth of 10 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. The coverage of the Adobe RGB 1998 color space is 70 % according to the manufacturer. According to the manufacturer, the coverage of the SRGB color space is 95 %.
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 1100 : 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 120000000 : 1 of dynamic contrast ratio for the monitor VX4380-4K 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
Without the stand, the monitor comes with a width of 96.5 cm , a height of 56.1 cm and about 6.5 cm.
The size of the monitor (stand included) is 65.2 x 96.5 x 24.1 cm (HxWxD). As for the weight, ViewSonic states a total weight of 14.42 kg with stand. A wall mount should be designed for at least 11.3 kg to hold the VX4380-4K 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 ViewSonic cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. The monitor VX4380-4K offers the option of adjusting the tilt as required to create an ergonomic working environment and reduce visual fatigue. The angle of inclination to the rear is 12. The monitor can be tilted forward by 5 degree.

Power consumption
The average consumption figure for VX4380-4K is 66 w. The maximum power consumption (peak) specified for this monitor is 84 w. In standby mode, the device consumes approximately 0.5 w. In ECO mode, the monitor consumes 52 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
During operation, the ambient temperature must not exceed 40 °C , to ensure full functionality. 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.
