Within this article we will take a closer look at the technical specifications of the UltraSharp U3011 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
According to the manufacturer, the display measures 29 inches ( 75.6 cm on the diagonal). The size specification of a monitor refers to the screen diagonal, which is usually specified in inches. It is only comparable to a limited extent for different formats. For example, a conventional 4:3 monitor with the same screen diagonal has 6% less width, but 13% more height and a total of 7% more surface area than a monitor in 16:10 format. Despite the difference in working area, wider monitors are better suited for consuming games or current movies, for example. It is also easier to display several documents simultaneously on widescreen monitors. So, it depends on the current use case whether the aspect ratio of 1.6 : 1 makes sense for the intended use case. 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 81.6 % 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 H-IPS panel. The panel has a resolution of 2560 x 1600 px. The pixel density is 101 ppi. The pixel pitch is 0.251 mm. The continuous possible brightness specified by the manufacturer Dell is 370 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 U3011 30 khz to 112.5 khz. Vertically, however, the image renews at a minimum rate of 56 hz up to 86 hz. The analog refresh rate of this monitor is 30 khz to 99 khz. The frame rate in the analogue range is vertical at the UltraSharp U3011 56 hz to 86 hz. The minimum response time of the monitor is ms. The maximum 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 10 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 99 % according to the manufacturer. According to the manufacturer, the coverage of the NTSC 1953 color space is 117 %. 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 100000 : 1 of dynamic contrast ratio for the monitor UltraSharp U3011 cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio.

The monitor supports all HDR modes listed here:
screen design
The following dimensions must be planned for a free-standing stand without attached feet/stand: 45.3 cm x 69.4 cm x 9.4 cm (HxWxD)
The size of the UltraSharp U3011 on the desk is likely to be particularly relevant for most users. Dell specifies a space requirement of 48.1 x 69.4 x 21.1 cm (HxWxD) with the included stand. The device weighs in total (i.e. also measured with the stand) 14.46 kg. The monitor UltraSharp U3011 without the stand weighs 9.3 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 9 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 U3011 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 U3011 can be tilted. The angle of inclination to the rear is 19. The monitor can be tilted forward by 3 degree.
Ports
The monitor can be connected via 1 VGA ports.
camera
This monitor does not have a camera.

Features
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 LM300WQ5-SLA1.

Power consumption
On average, the monitor consumes approximately 110 w. The maximum power consumption (peak) specified for this monitor is 250 w. In standby mode, the device consumes approximately 2 w. When switched off, on the other hand, the monitor consumes only 0.5 w. In ECO mode, the monitor consumes 85 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 3.657 km. During operation, the ambient temperature must not exceed 35 °C , to ensure full functionality. Below a temperature of 5 °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.
