How to choose a monitor for work
Everyone knows what a great burden on a person's vision is given by working at a computer. With frequent and prolonged activities near the computer, vision is often impaired, so it is necessary to select a monitor that will provide the least strain on the eyes and, at the same time, will demonstrate the high performance of image transmission from the computer. Most likely, the performance of the monitor in this situation will be in the first place.
Today on the market, there are a huge number of companies that produce monitors for computers, and they are doing large number of monitor models that have differences in appearance design and technical characteristics.
Examining the offered types of monitors, you will see many options that, when choosing, you can satisfy almost all the preferences and requests of the consumer. If we classify monitors by size, then we can distinguish those in which the diagonal sizes is from 10 cm to 2 m.
The second characteristic of monitors is called resolution. Resolution is a measure that shows the ratio of the length and width of the screen to the displayed image. The most comfortable to use are monitors with a screen resolution of HDTV (Full HD) (FHD) 1080p 1920 × 1080 pixels. Monitors with a screen resolution of WQXGA (WQHD) (QHD) 2560 × 1440 pixels will also be good. But it is the computer user who needs to choose the resolution.
When choosing a monitor, you need to determine the real and specific purposes of its use. If you are an avid video game fan, then of course you need a monitor capable of delivering the highest possible performance. If the monitor will be used for office work or home, then there is no need to overpay for powerful characteristics, you can opt for a monitor with average or low performance.
If you plan to watch movies, you need a monitor with a large diagonal length, and also with a high quality of image transmission from the computer. And when the user needs a monitor for all of the above options and situations, then a medium-sized screen with high performance is the right choice. So that you do not make a mistake with the choice of a monitor for a computer, we will tell you about them in more detail.
Today LSD and LCD monitors are recognized as the most common. They have a flat-screen. Models of CRT monitors with a convex screen are no longer in demand among consumers and are out of production.
LCD is how liquid crystal models are denoted. The structure of LCD monitors is as follows. The monitor itself, consisting of two glass plates, between which liquid crystals are mounted. Any crystal has a transparent layer of electrodes available, which protects the crystals and participates in color rendering. The image from the computer is fed to the monitor using electrical signals of a certain predetermined power, after which the electrical signals enter a special filter that centers them.
The electrical signals are sent to liquid crystals, which transmit the enhanced image to a subsequent filter. The second and most recent filter is responsible for the color gamut of the displayed image. The filter centers and sorts color correctly by crystal. Subsequently, after the filter, the image falls on the second plate of glass, this image is already seen by a person.
LSD monitors use a similar operating principle to LCD monitors. An important difference is that LSD monitors use three glass plates. This additional plate makes it possible to make the image even clearer, makes the screen backlight even brighter. This quality advantage should be considered when buying a monitor. Make sure the model you choose has LSD capabilities.
In the question of the influence of radiation from a computer monitor on a decrease in human vision, it should be noted that more and more advanced technologies are used in modern models that significantly reduce the harmful effects on human health. Compared to monitors that were released earlier, in the time interval from 1990 to 2004, the new options allow you to work at a computer for a long time without harm to your eyes.
Even if you spend more than five hours in front of a computer screen, you will feel completely normal. Although it is still worth limiting the time of working at the computer to reasonable limits, because absolutely safe machines for human health have not yet been invented.
