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 ThinkVision T27q-20 from Lenovo.
Display
27 inches ( 68.5 cm on the diagonal) offer sufficient space for texts in any office applications, for example. As already known, two monitors with different outer dimensions can have the same screen diagonal. In the case of the monitor ThinkVision T27q-20 , 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, some enthusiasts may also be interested in the ratio between the monitor area and the actual display. This refers to the general ratio between the non-display area and the display. In other words, approximately 88.3 % of the front surface of the monitor consists of the display, while the rest is made up of screen edges and cannot display an image. When arranging several monitors next to each other, it is advisable to 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 109 ppi. The pixel pitch is 0.233 mm. The continuous possible brightness specified by the manufacturer Lenovo is 350 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. 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.
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 Lenovo 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 3000000 : 1 of dynamic contrast ratio for the monitor ThinkVision T27q-20 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
For a possible wall mounting or comparison to the currently owned monitor at the beginning, the dimensions of the monitor without stand/feet: 36.9 cm x 61.4 cm x 4.6 cm (HxWxD)
If you want to place the monitor described here on the desk without a wall mount, you should allow for 42.9 x 61.4 x 20.8 cm (HxWxD) of space. The device weighs 7.44 kg with the stand in place. A wall mount should be designed for at least 4.93 kg to hold the ThinkVision T27q-20 neatly and securely. 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 13.5 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 90 degree. To the right, the monitor can be rotated by 90 degree. The ThinkVision T27q-20 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 ThinkVision T27q-20 can be individually adjusted to optimize the viewing angle and increase comfort during use. The angle of inclination to the rear is 35. The monitor can be tilted forward by 5 degree.

Power consumption
The average consumption was given by Lenovo as 23 w. The maximum power consumption (peak) specified for this monitor is 65 w. In standby mode, the device consumes approximately 0.5 w. When switched off, on the other hand, the monitor consumes only 0.3 w. In ECO mode, the monitor consumes 17.4 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. 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 45 °C. 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.
