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 PQ22UC from Asus.
Display
Let's start with the most important component of a monitor, the display. Depending on the aspect ratio of height and width, monitors can be rather wide or square, for example. Besides the pure physical dimensions, the resolution of the display and thus the quality of the display is also decisive here. For easy comparability, however, screen sizes are usually given in inches. This unit of measurement simply compares the diagonal length from the lower left to the upper right corner of the display and is thus universally applicable. This device has a screen diagonal of 21 inches ( 54.6 cm on the diagonal). The size specification of a monitor refers to the screen diagonal, which is usually specified in inches. It is only comparable to a limited extent for different formats. For example, a conventional 4:3 monitor with the same screen diagonal has 6% less width, but 13% more height and a total of 7% more surface area than a monitor in 16:10 format. Despite the difference in working area, wider monitors are better suited for consuming games or current movies, for example. It is also easier to display several documents simultaneously on widescreen monitors. So, it depends on the current use case whether the aspect ratio of 1.778 : 1 makes sense for the intended use case. Approximately 80.1 % of the front of the monitor is taken up by the display, while the remaining area consists of screen edges that cannot display any image information. If you want to set up several monitors next to each other, it is advisable to choose monitors with narrow edges. The display is a OLED panel. The panel has a resolution of 3840 x 2160 px. The pixel density is 204 ppi. The pixel pitch is 0.125 mm. The continuous possible brightness specified by the manufacturer Asus is 140 nt. The monitor's panel reaches a peak brightness of 335 nt. The built-in panel ensures stable color reproduction of the image, even at deviating viewing angles, by means of its 178 ° (horizontal) viewing angle. Asus promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the PQ22UC 27 khz to 134 khz. Vertically, however, the image renews at a minimum rate of 24 hz up to 60 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 99 % according to the manufacturer. According to the manufacturer, the coverage of the DCI-P3 color space is 99 %. According to the manufacturer, the coverage of the SRGB color space is 100 %.
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 Asus has a static contrast ratio of 10000000 : 1 , according to the manufacturer.
HDR
The monitor supports all HDR modes listed here:
- HDR 10
- HDR HLG
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: 31.3 cm x 51 cm x 8 mm (HxWxD)
The size of the monitor (stand included) is 38.2 x 51 x 12.8 cm (HxWxD). The device weighs in total (i.e. also measured with the stand) 2.1 kg. A wall mount should be designed for at least 1.5 kg to hold the PQ22UC neatly and securely.
Rotate, tilt and swivel
The monitor from Asus cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. Thanks to the tilt function of the PQ22UC 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 20. The monitor can be tilted forward by 2 degree.

Power consumption
The average consumption was given by Asus as 38 w. In standby mode, the device consumes approximately 0.8 w. When switched off, on the other hand, the monitor consumes only 0.35 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 50 °C during operation. Below a temperature of 0 °C , the monitor from Asus should again not be used. The maximum storage temperature should be according to Asus 60 °C. Minimal were given by Asus 20 °C.
Packaging
The monitor is packaged in a cardboard box measuring 57.6 x 71.3 x 18.2 cm (height x width x depth). The box together with the monitor weighs about 8.8 kg.
