MODERN MONITOR

Monitor - a device designed to play the video signal and visual display of information received from the computer. The principal difference from the TV is the absence of a built-in tuner designed for receiving high-frequency signals of terrestrial (terrestrial) broadcasting. In addition, most monitors do not have a sound path and loudspeakers.

Existing monitors today differ in device size, screen diagonal size, refresh rate, security standards and much more. The first electron beam monitors were vector. In monitors of this type, the electron beam creates lines on the screen, moving directly from one set of coordinates to another. Because of this, there is no need to split the screen into pixels. Later appeared monitors with raster scanning. In them, the electron beam scans the screen from left to right and from top to bottom, each time running through the entire surface of the screen. The next step in the development of electron-beam monitors was a color image, for which it was necessary to use not one, but three electron beams. Each of them highlighted certain points on the surface of the display.

The monitor as a means of visual display of information has existed for a long time and has experienced several revolutionary changes in its history. If not a few years ago, manufacturers mainly fought for the possibility of providing high basic characteristics of the “picture”, then today there is already competition between different concepts for the implementation of this device. Modern types of monitors differ in many criteria, which determine not only the image quality, but also the presence of communication interfaces, energy saving indicators, functionality and other performance characteristics.

A modern monitor consists of a screen (display), a power supply, control boards and a housing. Information for display on the monitor comes from an electronic device that forms a video signal (in a computer, a video card or a graphics processor core). TV can also be used as a monitor.

At first glance, modern monitors for computer equipment are no different from TVs. At least, if you compare small models of similar size, the difference can be overlooked. And yet it is. So, if a classic TV is an autonomous device that receives and reproduces audio and video signals from cable and satellite stations, the monitor is a hardware tool for processing and providing graphic information, the source of which is a special video card. As for external differences, they are most clearly expressed by the type of monitor on a laptop, which can be represented by one of the matrices of the liquid crystal display family. In particular, the formats of TN, MVA matrices and the most modern development - IPS are widespread today. Compared to the same TVs, these modules provide higher quality and detail of the reflection of graphic information per unit of screen area.

Leaders of the segment are such manufacturers as BenQ, ASUS, DELL, Samsung, etc. The developers of these companies strive to master not only the main technological directions in terms of improving image quality, but also place emphasis on the specifics of how monitors interact with other computer components. The middle class is represented by brands like Hitachi, SuperSonic and Philips. Under the brands of these manufacturers all major types of monitors are available, from liquid crystal to the latest models on the OLED platform. And if this product can be inferior to the above-mentioned advanced companies in terms of technological excellence, it has an advantage in price terms. For example, the Philips Philips monitor, which is average in performance, can be purchased for 10–12 thousand rubles, while ASUS or BenQ offers similar in performance parameters cost about 15–18 thousand. At the same time, the budget segment is also popular. to represent their development and premium, and little-known companies. In this group you can find models of modern monitors with a price tag of about 5-7 thousand.
