What does computer resolution mean? What does it do

Computer resolution, to be exact, display resolution.

Display resolution is the resolution of the display when displaying the image, and the resolution is measured by dots, and the "dots" on the display refer to pixels. The numeric value of display resolution refers to the number of horizontal and vertical pixels on all viewing areas of the entire display. For example, the resolution of 800 600 means that 800 pixels are displayed horizontally and 600 pixels vertically on the entire screen.

The total number of horizontal and vertical pixels of the display resolution is always in a certain ratio, generally 4 or 8:5.

Each display has its own maximum resolution and is compatible with other lower display resolutions, so a monitor can be displayed in many different resolutions.

Although the higher the display resolution, the better, but there is also one factor to consider, that is, whether the human eye can recognize it. For example, on a 14-inch display with a maximum resolution of 1024 768, 800 600 is the highest resolution that the human eye can recognize (we tentatively call it the best resolution), and at the resolution of 1024 768, although the display can accurately display the image, the human eye can no longer accurately identify the screen information.

On a screen of the same size, the higher the resolution, the smaller the display. Because the size of the display is large and small, and the display resolution indicates the number of pixels in all viewing ranges, the same resolution has different effects on different displays, for example: 800 600 resolution, a 14-inch display is much more accurate than a 17-inch display with the same resolution.

Some of the better quality monitors (e.g. philips

15A, 14A), 14-inch monitors up to 1280 1024, 15-inch monitors up to 1600 1200.

Resolution is the precision of the screen image, and the number of pixels that the display can display. Since the dots, lines, and surfaces on the screen are made up of pixels, the more pixels a display can display, the finer the picture will be, and the more information can be displayed in the same screen area, so resolution is one of the most important performance indicators. Think of the image as a large chessboard, and the resolution is expressed as the number of intersections of all the meridian and latitude lines.

Resolution has a certain relationship with the display. The resolution of the computer is mainly related to the display, each display size has an optimal resolution, the graphics card will give the best resolution according to the display size after detecting the display, for the LCD monitor, the maximum resolution given is the best resolution.

Screen resolution refers to the number of pixels in vertical and horizontal directions, measured in px. Screen resolution determines the setting of how much information is displayed on a computer screen, measured in horizontal and vertical pixels. For a screen of the same size, when the screen resolution is low (for example, 640 x 480), fewer pixels are displayed on the screen, and the individual pixel size is larger.

When the screen resolution is high (for example, 1600 x 1200), there are many pixels displayed on the screen, and the size of individual pixels is relatively small.

Display resolution is the number of pixels displayed on the screen, resolution 160 128 means that the number of pixels in the horizontal direction is 160, and the number of pixels in the vertical direction is 128. When the screen size is the same, the higher the resolution, the more detailed and delicate the display effect will be.

The best resolution for a 22-inch monitor is 1680x1050 for a 16:10 ratio, a few 22-inch monitors use a 16:9 1920x1080 resolution, and a rare 22-inch monitor uses 1920x1200 resolution.

The best resolution of a 19-inch monitor is generally 1400x900, and the display effect can achieve the best visual acceptance range.

There are four main ratios of the length and width of the LCD screen on the market:

9The first two are general screens, and the last two are wide screens. Turn on the computer, click on the computer start menu, click on the control panel, click on appearance and personalization, find adjust screen resolution under the display in appearance and personalization and click on it, and then you need to identify your computer and select the computer resolution.

There is a direct relationship between resolution and pixels of an image.

A resolution of 640 x 480 will have a resolution of 307,200 pixels, which is often referred to as 300,000 pixels, and a resolution of 1600 x 1200 will have 2 million pixels.

This shows that the two digits of the resolution represent the units of the number of points in length and width. The aspect ratio of a digital** is usually 4: for LCD monitors and traditional CRT displays, resolution is one of the important parameters.

Traditional CRT displays support more flexible resolutions, while LCDs have a fixed pixel pitch, so they don't support as many display modes as CRTs. The optimal resolution of the LCD, also known as the maximum resolution, is the resolution at which the LCD display can display the best image.

The usefulness of computer resolution is as follows:

1. The higher the resolution of the computer, the more pixels that can be displayed on the display, the more refined the picture, and the more information that can be displayed in the same screen area;

2. Think of the whole image as a large chessboard, and the representation of computer resolution is the number of intersections of all meridians and latitudes, and the smaller the display screen, the clearer the image, on the contrary, when the display screen size is fixed, the higher the computer display resolution, the clearer the image.

The usefulness of computer resolution is as follows:

1. The higher the resolution of the computer, the more pixels the display can display, the more detailed the picture, and the more information can be displayed in the same screen area;

2. Imagine the whole image as a large chessboard, and the representation of the computer resolution is the number of hidden points of all the warp and weft sketches, the display resolution is a certain situation, the smaller the display screen, the clearer the image, on the contrary, when the size of the display screen is fixed, the higher the computer display resolution, the clearer the image.

1. Computer resolution, strictly speaking, is called display resolution, which is the expression of the image pixels displayed on the display after the computer graphics card outputs the display signal.

2. Resolution refers to the number of pixels displayed per unit area. The physical resolution of an LCD display is fixed, and in the case of a CRT display, different resolutions can be changed by simply adjusting the deflection voltage of the electron beam. However, in the liquid crystal display, it is much more complicated to realize the rock and ambush, and the display effect must be simulated through calculation, and the actual resolution has not changed.

Since not all pixels are enlarged at the same time, there is a scaling error. When the LCD is used in a non-standard resolution, the text display effect will deteriorate, and the edge of the text will be blurred.
