Anonymous users2024-02-10Compared with CRT displays, LCD monitors are more "delicate", how to maintain them?
1.How to clean the LCD screen: After the LCD is used for a period of time, you will find that the display screen often absorbs a layer of dust (it is more obvious after turning off the LCD), and sometimes it will accidentally stick to various water stains, which will definitely greatly affect the visual effect, how to clean it?
Turn off the power of the LCD and remove the power cord plug and the graphics card cable plug.
Move the LCD to a place with better natural light, so that you can see where the dust is, which is more conducive to targeting, so as to achieve a better cleaning effect.
Cleaning the LCD screen does not require any special solution or cloth, in the author's experience, water + soft lint-free cloth or cotton lint-free cloth is the best LCD screen cleaning tool (no lint paper towel is OK). When cleaning, you can use a cotton lint-free cloth dipped in water and then wring it out slightly, and then use a slightly damp soft lint-free damp cloth to gently wipe the dust on the display screen (do not squeeze the display screen hard), it is recommended to wipe from one side of the display screen to the other until it is all wiped clean, do not wave indiscriminately.
Tip: Do not wipe with a hard cloth or hard paper. At the same time, do not use cleaning liquids containing alcohol or acetone or detergents containing chemical ingredients, and do not spray liquids directly onto the screen to prevent the liquid from penetrating into the protective film.
After cleaning the LCD screen with a damp, soft, damp cloth, you can use a damp cloth that has been wrung dry to clean it again. Finally, let the water vapor on the LCD screen air dry naturally in a ventilated place.
2.Other maintenance points.
1) Avoid vibrations. LCD screens are fragile and need to be protected from strong shocks and vibrations. Do not put pressure on the LCD screen or collide or squeeze on the back cover of the LCD display.
2) Avoid using the screen for a long time. Long-term work is not a good thing for LCDs, and if you don't use it, be sure to power off the display. In the same way, be cautious when using LCD wallpapers and screensavers.
Most of the wallpapers and screensavers have bright colors, and the light and dark changes are strong, and long-term use will distort the LCD color, which will affect the life of the LCD display. So, it's best to use a monochrome screen and remove the screensaver when using LCD.
3) Anti-electromagnetic interference. Whether it is a CRT or LCD display, it is necessary to stay away from objects with strong magnetic fields, as the strong surrounding magnetic field will generate additional voltage inside the display, which will affect the stability of the display voltage. Being in a strong magnetic field for a long time will also distort the color, which will affect the display effect and life of the LCD.
4) Pay attention to moisture. Do not let any moisture enter the LCD, if the indoor humidity is too high, the inside of the LCD may produce condensation, resulting in leakage and short circuit of the LCD, and in serious cases, the display will be burned. For some southern areas with high humidity, the LCD can be placed in a warmer and drier place, or the back of the LCD can be regularly baked with a low-power desk lamp to allow the moisture in it to evaporate.

Anonymous users2024-02-091.Avoid unnecessary vibrations
LCD can be regarded as the most sensitive electrical equipment, LCD contains a lot of glass and sensitive electrical components, so that the screen is very fragile, try to avoid strong shock and vibration, strong impact can easily lead to damage to the LCD screen and CFL unit. Be careful not to put pressure on the LCD display surface, and the bad habit of pointing in front of the screen must be corrected.
2.Do not attempt to disassemble the LCD
One rule is to never disassemble an LCD. Even after being turned off for a long time, the CFL inverter in the background lighting component can still carry a high voltage of about 1000V, which can cause serious personal injury. So never try to disassemble or alter the LCD display to avoid high pressure.
Unauthorized repairs and changes can result in the display temporarily or even permanently rendering it unfunctional. If there is a fault, it is recommended to take it to a professional repair station for repair.
3.It is usually best to use the recommended display resolution
The display principle of an LCD monitor is completely different from that of a CRT monitor. It is a direct one-to-one pixel display. The LCD display working at the optimal resolution converts the analog display signal output by the graphics card into a display signal with specific address information (the absolute address of the pixel on the screen), and then sends it to the LCD board, and directly adds the display signal to the driver tube on the corresponding pixel.
For such point-to-point output situations, it is important to use the optimal resolution recommended by the display.
4.Avoid burning out the inside of the screen
As mentioned earlier, leaving the LCD on for a long time will reduce its lifespan. Therefore, in order to avoid the occurrence of such situations, the following measures can be taken when not in use: 1) Turn off the monitor when not in use; 2) frequently change the content displayed on the screen at different intervals; 3) Reduce the brightness of the display to a darker level;
5.Maintain the humidity of the environment
Do not let anything with moisture properties enter the LCD, if the moisture has already entered the LCD, you must place the LCD in a warmer and drier place to allow the moisture and organic matter in it to evaporate, and then turn on the power. Powering an LCD with humidity can cause corrosion of the liquid crystal electrodes, which can cause permanent damage.

Anonymous users2024-02-08Pay attention to the temperature and moisture-proof The service life is calculated according to the long luminous time of the lamp, and the more one day of use, the less one day of life, remember to turn it off in time when not in use! It's not good to waste your money, it's not good to waste resources!

In fact, computer maintenance is still very simple, like the computer LCD screen is gray, gently wipe it with a soft cloth, and the general computer will have a special cleaning agent to buy, and it is not expensive. There is also pay attention to the usual use time of the computer, each time the use time is not too long, this hurts the computer, the host should also be cleaned regularly, dust accumulation will also make the computer run slower, and you must install anti-virus software, give the computer a regular physical examination. If you don't know how to clean the host, you can go to the after-sales service to help, but now Tencent PC Manager and Lenovo have held a computer cleaning day event, the first weekend of every month, the local service station will have professional technicians to help you clean your computer for free, what other problems.
