Within this article we will take a closer look at the technical specifications of the S2421HN monitor from Dell. 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
Let's start with the size of the display. It is 23 inches ( 60.4 cm on the diagonal) large and should thus offer enough space for all contents according to Dell. While classic CRT monitors were built with a screen ratio of 4:3, this monitor has a ratio of 1.778 : 1 (width to height). 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 90 % 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 IPS panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 92 ppi. The pixel pitch is 0.275 mm. The continuous possible brightness specified by the manufacturer Dell 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 178 ° (horizontal) viewing angle. Dell promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the S2421HN 30 khz to 83 khz. Vertically, however, the image renews at a minimum rate of 48 hz up to 75 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 (3H).
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 Dell has a static contrast ratio of 1000 : 1 , according to the manufacturer.

The monitor supports all HDR modes listed here:
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: 32.2 cm x 53.7 cm x 5.3 cm (HxWxD)
The size of the S2421HN on the desk is likely to be particularly relevant for most users. Dell specifies a space requirement of 41.2 x 53.7 x 15.2 cm (HxWxD) with the included stand. The device weighs 4.1 kg with the stand in place. A wall mount should be designed for at least 3.3 kg to hold the S2421HN 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 Dell 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 S2421HN 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.

Features
- Flicker Free: Dell 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
- AMD FreeSync: By dynamically synchronizing the refresh rate of the S2421HN with the frame rate, AMD FreeSync minimizes judder and ensures smooth and enjoyable gameplay.
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 Dell offers a technology to reduce the blue content in its monitor S2421HN.

Power consumption
The average consumption was given by Dell as 16 w. The maximum power consumption (peak) specified for this monitor is 21 w. In standby mode, the device consumes approximately 0.3 w. When switched off, on the other hand, the monitor consumes only 0.3 w. In ECO mode, the monitor consumes 11.74 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 height at which the monitor may be operated, according to the manufacturer's specifications, is 5 km. For temperature, the maximum permissible ambient temperature is 40 °C. Below a temperature of 0 °C , the monitor from Dell 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 Dell 60 °C. Minimal were given by Dell -20 °C. According to the manufacturer, the monitor may be stored at a maximum height of 12.192 km.
Packaging
The box together with the monitor weighs about 5.9 kg.
