Within this article we will take a closer look at the technical specifications of the VP2756-4K monitor from ViewSonic. For this we will talk about all possible categories that could be relevant. To start with, we will look at the display, talk about the design and in the next section we will go into the features of the monitor. Other features such as power consumption, connectors and certifications will follow later in the text.
Display
Videos and/or other applications can be displayed on the monitor's 27 inches ( 68.5 cm on the diagonal). Television screens and monitors usually have an aspect ratio of 16:9 (approximately 1.78:1). More rarely, computer monitors are also found with an aspect ratio of 16:10.
Ultrawidemonitors are often manufactured with an aspect ratio of 21:9 (approximately 2.34:1). They are mainly used for computer games and as an alternative to two side-by-side screens. The first devices of this type came onto the market around 2014. Against this backdrop, the monitor VP2756-4K from ViewSonic faces an aspect ratio of 1.778 : 1. 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 90 % 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 IPS panel. The panel has a resolution of 3840 x 2160 px. The pixel density is 163 ppi. The pixel pitch is 0.155 mm. The continuous possible brightness specified by the manufacturer ViewSonic is 350 cd/m2. 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 VP2756-4K 15 khz to 130 khz. Vertically, however, the image renews at a minimum rate of 24 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 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 78 % according to the manufacturer. According to the manufacturer, the coverage of the DCI-P3 color space is 80 %. According to the manufacturer, the coverage of the NTSC 1953 color space is 77 %. According to the manufacturer, the coverage of the SRGB color space is 100 %. Additionally, this monitor is Pantone validated.
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 VP2756-4K cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio.

The monitor supports all HDR modes listed here:
screen design
Without the stand, the monitor comes with a width of 61.3 cm , a height of 36.3 cm and about 5.3 cm.
If you want to place the monitor described here on the desk without a wall mount, you should allow for 41 x 61.3 x 21.5 cm (HxWxD) of space. The base itself has a depth of 21.5 cm. The device weighs 7.5 kg with the stand in place. According to ViewSonic , you can expect a weight of about 5.1 kg without the stand. 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 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 90 degree. To the right, the monitor can be rotated by 90 degree. The VP2756-4K can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 120 degree. Pivoting to the right is possible up to 120 degree. Thanks to the tilt function of the VP2756-4K monitor, the screen position can be flexibly adjusted to minimize dazzling light sources and ensure optimum visibility. The angle of inclination to the rear is 21. The monitor can be tilted forward by 5 degree.
Ports
camera
Loudspeaker
The monitor from ViewSonic 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 2 w power.
Features
- The display/monitor supports Frame Rate Compensation.
Anyone who works a lot on the computer spends many hours a day in front of the screen. Excessive screen work can damage the eyes. This effect can be particularly pronounced during the darker hours and in the winter months. Many monitor manufacturers have now reacted and offer technologies and settings to reduce the blue component, which is primarily controversial. Depending on the manufacturer, these can be called "Low Blue Light", "Low Blue Light Technology", "SoftBlue" or even "Eye Saver Mode" and function differently. However, it is only important that ViewSonic offers a technology to reduce the blue content in its monitor VP2756-4K.
The monitor VP2756-4K has a split-screen functionality, which allows us to display multiple video inputs/signals simultaneously on the monitor. This feature divides the screen area into several parts, each of which displays an image of a different input signal.WiFi / Bluetooth
Power consumption
The average consumption was given by ViewSonic as 24 w. The maximum power consumption (peak) specified for this monitor is 28 w. In standby mode, the device consumes approximately 0.3 w. In ECO mode, the monitor consumes 19.3 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, 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 20 °C.
Packaging
The monitor is packaged in a cardboard box measuring 46.5 x 74 x 22.5 cm (height x width x depth). The box together with the monitor weighs about 10.2 kg.
