What is screen resolution? How to check computer screen resolution

Regularly in contact with computers, we often hear the phrase screen resolution. However, do you really understand the definition of screen resolution and how to check computer screen resolution? Let's find out with TipsMake through the following article!

What is screen resolution?

Screen resolution is understood as the pixels displayed on the screen. The number of pixels will be arranged horizontally and vertically.

For example : The HD resolution of a 16:9 screen is 1366 x 768 pixels. This means that a horizontal row of the screen will have 1366 pixels and 768 horizontal rows, a vertical row will have 768 pixels and 1366 vertical rows, so the total number of pixels displayed on the screen is 1,049,088 pixels.

The more pixels a screen has, the sharper the image will be, but this also depends on the quality of the screen and the display ratio of the screen.

As for the sharpness of the screen, it also depends on the screen size.

For example: If the same screen is equipped with a resolution of 1366 x 768 pixels, then compared to a 15.6 inch screen, a 14 inch screen will display more clearly. On a larger screen, the pixels will also be spread out more, the distance between pixels is larger, so the display will be less clear.
