Today we will look at the monitor ThinkVision Pro2820 from Lenovo from the year 2013. Within this article, we will first take a closer look at the most important feature of a monitor -the display-, then the design, and in the next section we will go into the features of the monitor. Of course, power consumption, certifications, connectivity and other important details will also be considered.
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 ThinkVision Pro2820 has a display size of 28 inches ( 71.1 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. Let's keep it short and sweet. The monitor has an aspect ratio of 1.778 : 1. Around 80.1 % of the front surface of the monitor consists of the display, while the rest is made up of screen edges that cannot display images. If you want to place several monitors next to each other, it is advisable to prefer those with narrow edges. The display is a MVA panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 78 ppi. The pixel pitch is 0.323 mm. The continuous possible brightness specified by the manufacturer Lenovo 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. Lenovo promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the ThinkVision Pro2820 30 khz to 81 khz. Vertically, however, the image renews at a minimum rate of 50 hz up to 75 hz. The minimum response time of the monitor is ms. The display panel is Anti-glare/Matte.
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 %.
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 Lenovo has a static contrast ratio of 3000 : 1 , according to the manufacturer.

screen design
Lenovo Specifies the following dimensions for the monitor ThinkVision Pro2820 without stand/feet: 39.7 cm x 66.5 cm x 5.8 cm (HxWxD)
If you want to place the monitor described here on the desk without a wall mount, you should allow for 44.3 x 66.5 x 28.9 cm (HxWxD) of space. If you want to place the monitor on a table or even transport it, you should expect a weight of 8.11 kg with the stand screwed in. According to Lenovo , you can expect a weight of about 5.11 kg without the stand. 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 cm. This value is always measured from the bottom edge of the screen.
Rotate, tilt and swivel
The monitor from Lenovo 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 ThinkVision Pro2820 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. Thanks to the tilt function of the ThinkVision Pro2820 monitor, the screen position can be flexibly adjusted to minimize dazzling light sources and ensure optimum visibility. The angle of inclination to the rear is 25. The monitor can be tilted forward by 5 degree.
Ports
The monitor can be connected via 1 VGA ports.

Power consumption
The average consumption was given by Lenovo as 60 w. The maximum power consumption (peak) specified for this monitor is 90 w. In standby mode, the device consumes approximately 1.2 w. When switched off, on the other hand, the monitor consumes only 0.5 w. In ECO mode, the monitor consumes 50 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. The maximum permissible ambient temperature is 45 °C during operation. Below a temperature of 0 °C , the monitor from Lenovo 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 95 percent. The minimum humidity during storage should not fall below 5 percent. The maximum storage temperature should be according to Lenovo 60 °C. Minimal were given by Lenovo -20 °C. According to the manufacturer, the monitor may be stored at a maximum height of 12.192 km.
