What you need to know about screen resolution
In order for the application of the technique not only to simplify the solution of important tasks, but also to be safe, it is necessary to have a certain set of knowledge regarding how to use 4: 3 resolution 5: 4, 16: 9 or other existing variations. The uninformed immediately raises two questions: what do the figures quoted mean and how they can affect the safety of human health
The numbers located next to the word "resolution", 4: 3 for example, in the initial sense indicate the ratio of the sides of the screen (length and height) to each other. However, the considered values are indicated by the manufacturer to determine the main technical features of the screens of various devices. In particular, a 4: 3 screen resolution determines which technology is applied to the device in question: QVGA, VGA, PAL, SVAGA, SXGA +, UGA or QXGA, which characterize the quality of the displayed pictures.
What effect does screen aspect ratio have?
Everyone knows that the use of gadgets over a long period of time affects the eyes. This is especially true for entertainment. To provide less strain on the eyes, the image on the screen should not be elongated or narrowed. There is much evidence that when a 4: 3 resolution is used, the displayed image looks most clearly and clearly. With this ratio, working at a computer does not cause much discomfort. That is why for many computer and mobile games, the resolution is usually considered 4: 3.
But recently, with the development of screen technologies, 16: 9 resolution has become increasingly popular. Using the recommended parameters, each of us reduces the risk of visual impairment when spending a long time at a computer or other device.
