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 UltraSharp U2913WM from Dell.
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 28 inches ( 73 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 UltraSharp U2913WM from Dell faces an aspect ratio of 2.37 : 1. If you want to pay attention to special aesthetics or simply want to place several monitors next to each other, you should pay attention to the ratio between display and non-display. The UltraSharp U2913WM is a monitor with a ratio of 86 % between usable and non-usable front surface. The display is a AH panel. The panel has a resolution of 2560 x 1080 px. The pixel density is 96 ppi. The pixel pitch is 0.263 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. The refresh rate is horizontally seen at the UltraSharp U2913WM 30 khz to 94 khz. Vertically, however, the image renews at a minimum rate of 56 hz up to 86 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 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 %. 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. 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 2000000 : 1 of dynamic contrast ratio for the monitor UltraSharp U2913WM cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio.

screen design
Dell Specifies the following dimensions for the monitor UltraSharp U2913WM without stand/feet: 31.7 cm x 69.9 cm x 6.1 cm (HxWxD)
If you want to place the monitor described here on the desk without a wall mount, you should allow for 35.8 x 69.9 x 19.4 cm (HxWxD) of space. If you want to place the monitor on a table or even transport it, you should expect a weight of 8.34 kg with the stand screwed in. Without stand, the monitor weighs 5.76 kg. 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 cannot be rotated. The UltraSharp U2913WM can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 30 degree. Pivoting to the right is possible up to 30 degree. The monitor UltraSharp U2913WM can be tilted. The angle of inclination to the rear is 21. The monitor can be tilted forward by 4 degree.
Ports
The monitor can be connected via 1 VGA ports.

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 Dell 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 LG Display and has the model number LM290WW1-SSA1.
WiFi / Bluetooth
Power consumption
The average consumption figure for UltraSharp U2913WM is 42 w. The maximum power consumption (peak) specified for this monitor is 90 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 32 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. There are 1.5 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 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 10.668 km.
