Within this article we will take a closer look at the technical specifications of the P2421DC 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
Texts, videos and/or other applications can be displayed on the 23 inches ( 60.4 cm on the diagonal) of the monitor. As already known, two monitors with different outer dimensions can have the same screen diagonal. In the case of the monitor P2421DC , we find an aspect ratio of 1.778 to 1. This means that for every 1 pixels in height, 1.778 pixels in width are added. For comparison: A classic CRT monitor had an aspect ratio of 4:3. 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 90.1 % 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 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.
HDR
The monitor supports all HDR modes listed here:
screen design
Without the stand, the monitor comes with a width of 53.7 cm , a height of 32.2 cm and about 4.2 cm.
If you want to place the monitor described here on the desk without a wall mount, you should allow for 35.6 x 53.7 x 16.6 cm (HxWxD) of space. The monitor P2421DC without the stand weighs 3.77 kg. This weight reduction should be taken into account for wall or arm mounting, since monitor arms have a maximum load capacity. 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 P2421DC 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 tilt of the monitor P2421DC can be individually adjusted to optimize the viewing angle and increase comfort during use. The angle of inclination to the rear is 21. The monitor can be tilted forward by 5 degree.
Ports
Daisy chaining is supported, which means that one cable (usually USB-C or Displayport) on the computer/laptop is sufficient to connect multiple monitors at the same time. One cable is connected to the computer/laptop and the second monitor is connected to the output of the first monitor.
camera
This monitor does not have a camera.
Loudspeaker
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 P2421DC.
WiFi / Bluetooth
Power consumption
The average consumption was given by Dell as 25 w. The maximum power consumption (peak) specified for this monitor is 127 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. 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 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 7.69 kg.
