Within this article we will take a closer look at the technical specifications of the UltraSharp U2311H 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 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 23 inches ( 58.4 cm on the diagonal). As already mentioned or known, monitors have a certain number of pixels in height and width. In most cases, this is not a 1:1 ratio, which is also the case with the monitor from Dell. This monitor has an aspect ratio of 1.778 : 1. This means that every 1.778 pixels in width 1 pixels in height are added. In addition to the aspect ratios and the specified screen diagonal, some enthusiasts may also be interested in the ratio between the monitor surface and the actual display. This ratio describes the general relationship between non-display and display. In other words, approximately 81.8 % of the front surface of the monitor consists of the display, while the rest consists of screen edges and cannot display an image. When setting up several monitors next to each other, it is advisable to give preference to models with the narrowest possible edges. The display is a e panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 95 ppi. The pixel pitch is 0.265 mm. The continuous possible brightness specified by the manufacturer Dell is 300 nt. The panel is illuminated by CCFL. 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 U2311H 30 khz to 83 khz. Vertically, however, the image renews at a minimum rate of 56 hz up to 75 hz. The minimum response time of the monitor is ms. The maximum 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. The coverage of the Adobe RGB 1998 color space is 69 % according to the manufacturer. 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 100 %.
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 10000 : 1 of dynamic contrast ratio for the monitor UltraSharp U2311H 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 monitor has a width of 54.7 cm without its attached stand/stand. The height is dimensioned at about 32.5 cm , while the for the depth of the monitor should be kept free at about 6.5 cm.
The size of the UltraSharp U2311H on the desk is likely to be particularly relevant for most users. Dell specifies a space requirement of 35.6 x 54.9 x 18.4 cm (HxWxD) with the included stand. If you want to place the monitor on a table or even transport it, you should expect a weight of 7 kg with the stand screwed in. Without stand, the monitor weighs 4.7 kg. 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 11.5 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 0 degree. To the right, the monitor can be rotated by 90 degree. The UltraSharp U2311H can be swiveled when mounted on the included stand. The monitor UltraSharp U2311H offers the option of adjusting the tilt as required to create an ergonomic working environment and reduce visual fatigue.
Ports
The monitor can be connected via 1 VGA ports.
camera
This monitor does not have a camera.
Loudspeaker
Features
- The display/monitor supports Frame Rate Compensation.
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 LM230WF2.
WiFi / Bluetooth
Power consumption
The average consumption was given by Dell as 33 w. The maximum power consumption (peak) specified for this monitor is 69 w. In standby mode, the device consumes approximately 1 w. In ECO mode, the monitor consumes 20 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 4.85 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.
