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 P2421D from Dell.
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 P2421D 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. 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). Approximately 90.1 % 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 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 Dell 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. Dell 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 (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 SRGB color space is 99 %.
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 the installation of the monitor, a space requirement of approximately 32.2 cm in height, 53.7 cm in width and 4.2 cm in depth is to be assumed.
The size of the P2421D on the desk is likely to be particularly relevant for most users. Dell specifies a space requirement of 35.6 x 53.7 x 16.6 cm (HxWxD) with the included stand. The monitor P2421D without the stand weighs 3.37 kg. This weight reduction should be taken into account for wall or arm mounting, since monitor arms have a maximum load capacity. 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 Dell 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 P2421D can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 45 degree. Pivoting to the right is possible up to 45 degree. The monitor P2421D offers the option of adjusting the tilt as required to create an ergonomic working environment and reduce visual fatigue. 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.
- 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 Dell offers a technology to reduce the blue content in its monitor P2421D.

Power consumption
The average consumption was given by Dell as 25 w. The maximum power consumption (peak) specified for this monitor is 55 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. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. There are 2.5 amps specified. 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. During operation, the ambient temperature must not exceed 40 °C , to ensure full functionality. Below a temperature of 0 °C , the monitor from Dell should again not be used. The humidity must not exceed 90 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 10 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 7.29 kg.
