What does the computer screen resolution mean?

The resolution in English is called resolution, which we call resolution in the mainland, and in Taiwan and Hong Kong, which is often called resolution. Resolution refers to the precision of computer screen graphics, that is, how many pixels the display can display. We know that the monitor screen is actually made up of dots, lines and surfaces of countless LCD dots. The more pixels the monitor can display, the finer the screen will be, and the more information will be displayed in the same screen area. We can understand that the more points that are evenly distributed in one area, the more full the area will be, and the more it looks like a complete plane, and the more points, the finer and clearer the entire surface.

Generally speaking, the resolution refers to the product of a horizontal pixel number and a vertical image number. For example, our most common 1024x768 resolution means that the level of pixels is 1024, the number of vertical pixels 768, the entire region has a pixel of 1024x768=786432 (a). The higher the resolution, the more pixels in the area of the display screen, the more sophisticated the image, the more delicate and clear display effect.

In addition, the resolution of the display quality is also related to the size of the display, the larger the size of the screen should have a higher resolution to achieve a more exquisite image effect. I believe it is easy to understand that because of the size of the display, the required pixel points must be increased to achieve higher quality. The final resolution is also influenced by such factors as CRT point spacing and video bandwidth. Among them, it is closely related to the refresh frequency, strictly speaking, only when the refresh rate is "No flicker refresh frequency", the monitor can reach the highest resolution, can be called the maximum resolution of this display.

Edit conclusion: High resolution is an important prerequisite to ensure the clarity of color display. The point distance of display is one of the basis of high resolution, and the point distance of large-screen color display is generally 0.28,0.26,0.25. High-resolution on the other hand refers to the display in the horizontal and vertical display can reach the largest pixel points, generally have 320x240,640x480,1024x768,1280x1024 and so on, good large-screen color display can usually reach 1600x1280 high resolution. Higher resolution not only means higher clarity, it also means that more content can be displayed in the same display area. For example, only one page of content can be displayed at 640x480 resolution, and two pages can be displayed at the 1600x1280 resolution. Finally, with the popularity of high-definition technology, usually what we call the 720P, 1080P high-definition movies required screen resolution is usually reached 1920x1080 (width x high), 720P is 1280x720, because the naked eye is more sensitive to lateral resolution, so have a higher horizontal resolution, That is, the line number, which is usually the number of lines we call, has a decisive effect on the sharpness of high-definition images.
