Regarding the problem of the LCD screen, the problem of the LCD display, how to adjust it

Like desktop LCD displays, LCD screens rely on the backlight to irradiate liquid crystal molecules and transmit light, so the life of the LCD screen mainly depends on the backlight, not the liquid crystal molecules. When the screen is idle, it is better to turn off the LCD screen directly than to let the LCD screen protect the content.

Based on the above, dynamic screensavers are not good for LCD screens.

I use the liquid crystal one, which is good! But it's not as stable as a flat one. If you want to do the design or pure flat, if you want to use ordinary use at home or LCD!

After reinstalling the system, the graphics card driver is installed to adjust the optimal resolution: you need to adjust it from the display settings in the "My Computer" properties. 16:

The optimal resolution for a 10 scale 22 (vs. 20 ( inch widescreen LCD is: 1680 1050.

This resolution is the factory value, which means that only at the best resolution, the point distance of the monitor is the most reasonable, and the display effect is the best (the value of the best resolution is detailed in the manual and packaging of each monitor).

The resolution of LCD (liquid crystal display) is different from that of CRT (cathode ray tube) display, because it is affected by the actual number of cells in the LCD liquid crystal layer, it is a fixed value (i.e., point-to-point display), which generally cannot be adjusted arbitrarily, and is set and specified by the manufacturer. LCD displays can only produce the best image at this fixed value.

When the LCD display presents a display mode with a non-optimal resolution, it will be displayed in the following two ways:

The first is centered.

For example, if you want to display the resolution of SVGA800 600 on the screen of XGA1024 768, only 800 pixels in the center of 1024 and 600 network cables in the center of 768 can be displayed. Other pixels and network cables that are not rendered have to be kept dark. The whole frame appears to be zoomed out in the center, with shadows around the periphery.

The second is the extended display.

The upside is that no matter what resolution is used, the image displayed will always be applied to every pixel on the screen without creating shadows that surround the edges. However, since the image is extended to every pixel on the screen, it is inevitable that the image will be distorted and its sharpness and accuracy will be compromised.

Both of the above modes will have a great negative impact on the display effect of the monitor image, so it is not recommended to adjust the LCD to a non-optimal resolution. If some people have just started using the LCD and are not comfortable with the best resolution for a while, and feel that the characters are small, you can turn the corresponding "Project" font larger in the "Display Properties Appearance Advanced" of the desktop right-click mouse of the operating system.

While enjoying the unique display effect of LCD every day, don't forget the extremely important part of maintenance. Only when the LCD is well maintained can it serve users for a long time without failure. Here we invited Philips LCD display engineers to introduce us to some precautions for LCD displays.

I've heard that CRT monitors have phosphor burnouts, do LCDs have them? CRTs can burn out due to long-term operation, and this is also a problem for LCDs. So be sure to pay attention to turn off the display if you are not using it, or reduce the display brightness of the display.

Otherwise, it will lead to internal burnout or aging over time. This damage, once it occurs, is permanent and irreparable. In addition, if a fixed content is displayed continuously for a long time, it may cause some LCD pixels to overheat, which may cause internal burnout.

I've heard that LCD is very demanding on air humidity, is there such a thing? This statement is inaccurate, generally the humidity is kept between 30% and 80%, and the display can work normally, but once the indoor humidity is higher than 80%, condensation will occur inside the display. The internal power transformer and other coils are also prone to leakage when wet, and may even cause a short circuit in the wiring.

Therefore, the LCD display must pay attention to moisture-proof, and the display that has not been used for a long time can be powered on regularly for a period of time, so that the heat generated by the display when it is working will drive out the moisture in the machine. My LCD screen is dirty, how do I clean the surface of the display? If you find that there are stains on the surface of the display, you can gently wipe it off with a soft cloth with a little water, do not spill water directly on the surface of the display, water entering the LCD will cause a short circuit on the screen.

Is there anything else I need to pay attention to when using LCD monitors? LCD screens are very fragile, so avoid strong shocks and vibrations, LCDs contain a lot of glass and sensitive electrical components, falling to the floor or other similar strong blows can cause damage to the LCD screen and some other units. Also be careful not to put pressure on the LCD display surface.

There is one rule: 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 the LCD display to avoid high pressure. Unauthorized repairs and changes can result in the display temporarily or even permanently rendering it unfunctional. So when your hands and feet are really idle, don't touch the delicate and dangerous LCD!
