What you need to know about screen resolution

In order to make the application of the technique not only simplify the solution of important tasks, but also be safe, it is necessary to have some knowledge of how to use the 4: 3 resolution, 5: 4, 16: 9 or other existing variations.

The numbers next to the word "resolution", 4: 3 for example, in the original sense denote the aspect ratio of the screen (length and height) to each other. However, the values considered are specified by the manufacturer to determine the main technical features of the screens of different devices. In particular, the screen resolution of 4: 3, 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 images.

What is the effect of the aspect ratio of the screen

Everyone knows that using gadgets for a long period of time affects the eyes. Especially this applies to entertainment programs. To provide less eye strain, the image on the screen should not be stretched or tapered. There is much evidence that when the 4: 3 resolution is used, the displayed picture looks most clear and clear.
