At present, the screen size ratio of computers is generally 16:9 and 16: 10, and that ratio of 4:3 has almost been eliminated. Different sizes of monitors have different screen resolutions, and the resolutions corresponding to notebook sizes are as follows:
Notebook 12. 1 inch display resolution:1280 * 800;
Notebook 13.3 inch display resolution: 1024*600 or1280 * 800;
Notebook 14. 1 inch display resolution:1366 * 768;
Notebook 15.4 inch display resolution: 1280*800 or1440 * 900;
Notebook 15.6 inch display resolution:1600 * 900;
Desktop computer monitor resolution:
17 inch LCD or CRT, display resolution:1024× 768;
19 inch liquid crystal (ordinary screen), display resolution:1280×1024;
19 inch LCD (widescreen), display resolution:1440× 900;
The share of widescreen 16: 10 and widescreen 16: 9 of 22-inch LCD is 16: 10, respectively, and the resolution is 1680* 1050.
Influence of computer resolution on health;
Recently, a medical clinical study in the United States found that improper resolution setting of computer monitors may cause pathological changes. According to a survey, among people who usually use computers, if the screen resolution is set to a small resolution and small font below 800×600, they will get brain tumors. As a result of CT tomography, it is amazing to find that the brain tumor has grown into a square piece, which has to be said to be a bit amazing.
When we improve the resolution of the computer monitor, the number of pixels per square inch (DPI) increases, so we can block more radiation at this time, and we can also reduce radiation by increasing the font size and increasing the brown area. Senou, an expert from the US Centers for Disease Control, believes that when using computers, we'd better adjust the resolution to above 1024×768, which can reduce radiation well. If the resolution of the computer monitor is lower than 800×600, you should pay attention. Even if the amount of radiation is large and equipped with radiation protection devices, electromagnetic waves are still above the lethal dose.
