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 Akoya P55840 from Medion.
Display
Let's start with the size of the actual display. This is given in inches and measures the screen diagonal of the display. The monitor Akoya P55840 has a display size of 23 inches ( 60.4 cm on the diagonal). It should be noted, however, that displays in this category can have different dimensions, since square monitors, for example, can have the same diagonal as a widescreen monitor. Let's keep it short and sweet. The monitor has an aspect ratio of 1.778 : 1. 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 89.7 % 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 2560 x 1440 px. The pixel density is 123 ppi. The pixel pitch is 0.206 mm. The continuous possible brightness specified by the manufacturer Medion 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 178 ° (horizontal) viewing angle. Medion promises stable color reproduction moreover within a 178 ° vertical angle. Vertically, however, the image renews at a minimum rate of 60 hz up to 60 hz. The minimum response time of the monitor is ms. The average response time of the monitor is about ms. The display panel is Anti-glare/Matte.
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.
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 Medion 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 Akoya P55840 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 monitor has a width of 54 cm without its attached stand/stand. The height is dimensioned at about 32.2 cm , while the for the depth of the monitor should be kept free at about 4.4 cm.
The size of the monitor (stand included) is 40.7 x 54 x 21.6 cm (HxWxD). The device weighs 3.9 kg with the stand in place. According to Medion , you can expect a weight of about 3.4 kg without the stand. 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 Medion cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. The monitor Akoya P55840 can be tilted.

Power consumption
On average, the monitor consumes approximately 23 w. When switched off, on the other hand, the monitor consumes only 0.21 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 35 °C during operation. Below a temperature of 0 °C , the monitor from Medion 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 90 percent. The minimum humidity during storage should not fall below 5 percent. The maximum storage temperature should be according to Medion 60 °C. Minimal were given by Medion -20 °C.
