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 VP228N from Asus.
Display
According to the manufacturer, the display measures 21 inches ( 54.6 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 VP228N from Asus 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 relevant for some enthusiasts. This ratio represents the general relationship between non-display and display. In other words: Approximately 80.1 % of the front surface of the monitor consists of the display, while the remaining percent consists of screen edges and is not suitable for image reproduction. If you want to place several monitors next to each other, you should make sure you choose 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 102 ppi. The pixel pitch is 0.248 mm. The continuous possible brightness specified by the manufacturer Asus is 250 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. Asus promises stable color reproduction moreover within a 160 ° vertical angle. The refresh rate is horizontally seen at the VP228N 30 khz to 83 khz. Vertically, however, the image renews at a minimum rate of 50 hz up to 75 hz. The analog refresh rate of this monitor is 30 khz to 83 khz. The frame rate in the analogue range is vertical at the VP228N 50 hz to 75 hz. The minimum response time of the monitor is 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. 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 Asus 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 100000000 : 1 of dynamic contrast ratio for the monitor VP228N 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 following dimensions must be planned for a free-standing stand without attached feet/stand: 30.9 cm x 51.3 cm x 5.2 cm (HxWxD)
The size of the VP228N on the desk is likely to be particularly relevant for most users. Asus specifies a space requirement of 37.3 x 51.3 x 19.9 cm (HxWxD) with the included stand. The device weighs in total (i.e. also measured with the stand) 3.5 kg.
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. The tilt of the monitor VP228N can be individually adjusted to optimize the viewing angle and increase comfort during use. The monitor can be tilted forward by 5 degree.

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 Asus 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 Innolux TP Vision and has the model number M215HGE-L21 (Innolux) TPM215HW01-HTN01 (TP Vision).
WiFi / Bluetooth
Power consumption
On average, the monitor consumes approximately 21.1 w. In standby mode, the device consumes approximately 0.5 w. When switched off, on the other hand, the monitor consumes only 0.5 w. In ECO mode, the monitor consumes 14.48 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.
