TÜV Rheinland certificate
Display certification for safe blue light emissions and panel flicker. The presence of a certificate confirms the comfort of the screen for the eyes.
TÜV Rheinland is a large international concern headquartered in Cologne, Germany, providing a wide range of audit services. The company's specialists have developed and approved a number of tests for the compliance of the screens of mobile devices, monitors and TVs with the required level of eye protection from the harmful effects of display radiation on the user's vision on the other side of the screen. The authoritative opinion of TÜV Rheinland is respected in the tech community. Certificates from this body are issued to successfully tested electronics for the implementation of blue light filtering and screen flicker suppression technologies.
Portrait pivot
The screen is 90° rotatable on a stand, from landscape (horizontal) to portrait (vertical). The vertical orientation of the screen (
portrait mode) can be useful, for example, when working with large documents made in portrait orientation.
Height adjustment
The ability to move the monitor screen up and down relative to the base. This feature is very convenient for
adjusting the height of the screen — moving it on the mount is much easier than looking for a stand or resorting to other tricks.
Headphone holder
The presence in the design of the monitor of a special
device for hanging headphones. Such a device is usually located on the back side and looks like a small hook or protrusion for which you can hook the earpiece. Thanks to this function, the “ears” can be kept at hand at all times, while in unused time they will not take up space on the table.
Power consumption
Rated power consumption of the monitor. Usually, this item indicates the maximum power that the device can consume during normal operation — that is, the energy consumption at maximum brightness, the highest volume of the built-in acoustics, etc. Actual power consumption can be noticeably lower, however, when choosing, it is still best to focus on the value stated in the specifications.
In general, the lower the power consumption, the more economical the device in terms of electricity consumption (ceteris paribus). In addition, this characteristic can be useful when selecting an uninterruptible power supply for a PC and in other specific situations when it is necessary to accurately determine the power consumption of equipment.
Energy class (new)
This parameter characterizes the efficiency of electricity consumption. Classes are designated in Latin letters from A to G, in ascending order of energy consumption. Actually, this was originally conceived, until more energy-efficient models pulled up to class A, which eventually received the marking A +, A ++, A +++. Further development of technologies allowed us to go even further, and in order not to produce pluses in energy efficiency labeling, in March 2021, manufacturers returned to the previous indices from G to A, where A is the most energy efficient monitor. Accordingly, the 2021 models will have modern markings, while older models will be marked in the same way.
