How Do I Choose the Best Computer Screen?

Screen resolution refers to the resolution of the screen display. Screen resolution A setting that determines 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 a single pixel size is larger. When the screen resolution is high (for example, 1600 x 1200), there are more pixels displayed on the screen, and the size of a single pixel is smaller.

The meaning of pixel pitch is similar to the dot pitch of a CRT, and generally refers to the distance between two adjacent pixel points of a display screen. The picture we see is formed by many dots, and the fineness of the picture quality is determined by the dot pitch. The dot pitch is calculated by dividing the panel size by the resolution. Taking LCD as an example, the viewing area of a 14-inch liquid crystal display is generally 300mm × 190mm and the resolution is 1280 × 800. Therefore, the dot pitch of this LCD is calculated as 300/1280 = 0.2344mm or 190/800 = 0.2375mm. The smaller the dot pitch, the finer the image.

The best resolution of 16:10 ratio for 22 (21.5) and 20 (20.1) inch widescreen LCD monitors is: 1680 × 1050.

The 16: 9 ratio of 23 and 22 (21.5) -inch widescreen LCD monitors has the best resolution: 1920 × 1080.

The refresh rate of the LCD monitor uses the operating system's default 60Hz. Do not change it (do not change it regardless of the system default). LCD is not a CRT display, and its interior is not a cathode ray tube. It does not rely on an electron gun to bombard the phosphor powder on the picture tube to generate an image.

The LCD display passively emits light by illuminating the front liquid crystal panel with a rear lamp tube. The only differences are bright and dark, bright and dark. Therefore, LCD monitors do not have the principle of the progressive and interlaced screen of the electron gun (when the LCD monitor works, each pixel emits light from the beginning to the end, there is no flicker phenomenon), there is no concept of the refresh rate, and it is the same whether you change it The refresh frequency has no effect on all LCDs.

The graphics card has an adaptive function to the monitor. When you plug in the LCD monitor, the refresh rate option of the graphics card will not work automatically to protect the LCD monitor. So under Windows, you can't tune to 85Hz. This is the most basic common sense.
