Computer monitor

A computer monitor is a device designed to output visual (graphic, text, video) information.

Also, some monitors have built-in speakers, and can thus reproduce sound, but this feature is not included in the main characteristics of the monitor.

When buying or assembling a personal computer (PC) from individual parts, it is necessary to pay attention to the characteristics of the monitor, which we will consider below.

Previously, the monitor was called a display, now this name is rarely used.

1.The length of the diagonal and the proportion of the monitor

The diagonal is measured in inches. 1 inch is equal to 2.54 centimeters. Previously, the meter ("standard") in. Was the width of the thumb on the hand of an adult male. Inch for the diagonal of the monitor is represented by a "double quotation mark". In English, inch-inch, abbreviated in.

Most often you can find models of monitors with a diagonal equal to 15 ", 17", 19 ", as well as 21", 23 "and 27 inches. The latter option (27 ") is more suitable for professional designers, photo editors, video monitors, etc. Of course, it can be used by ordinary users, if there is an opportunity and desire to have a large monitor.

Currently, there are only two main types of monitors:

LCD,

ELT.Elt monitor

CRT monitor

As for the CRT, this abbreviation stands for "cathode-ray tube".

Similar monitors are similar to old TVs (they have almost the same size and weight). They are older, are rarely used, because of their large size, energy consumption and harm to the eyes.

In cathode-ray tubes, high voltage, fast charged particles and other technical things are used that are more harmful to users than the more modern LCD displays.

LCD - short for Liquid CrystalDisplay, which translates as a liquid crystal display. LCD monitors are more compact and light, since they can have an almost flat shape. So today they are used almost everywhere.

Often referred to as a monitor when packaged in a separate case, the display is the most-used output device on a computer. The display provides instant feedback by showing you text and graphic images as you work or play.

Most desktop displays use liquid crystal display (LCD) or cathode ray tube (CRT) technology, while nearly all portable computing devices such as laptops incorporate LCD technology. Because of their slimmer design and lower energy consumption, monitors using LCD technology (also called flat panel or flat screen displays) are replacing the venerable CRT on most desktops.

Resolution refers to the number of individual dots of color, known as pixels, contained on a display. Resolution is expressed by identifying the number of pixels on the horizontal axis (rows) and the number on the vertical axis (columns), such as 800x600. Resolution is affected by a number of factors, including the size of the screen.

As monitor sizes have increased over the years, display standards and resolutions have changed.
