What should I do if I encounter the problem of the display screen of the LCD screen flipper? Today, I will give you a brief introduction to how to solve the problem of the LCD screen flipper display screen.

Analysis of the resolution of the LCD display will always be blurred

The first situation: the display water ripples flicker

The main reason for the flickering of the water ripple of the display is caused by the wire, which can also be said to be one of the common faults. Generally, there are three common cables used by the host to connect to the display: VGA cable, DVI cable, HDMI cable, in addition to the unusual DP cable. Except for the DP cables, which are quite expensive, the other three cables are relatively cheap, and most of the cables are of no problem in quality. But if you still have the possibility to catch up with inferior quality wires.

The second case: the display has a blank screen and a black screen

The host has been turned on, other devices have no problem, the display has been powered on, the power indicator light indicates standby, but the display just doesn't light up. If your monitor has a black screen and the power indicator is off, please check whether the power cord is plugged in. If the power supply is surely plugged in, replace the power cord. If you can’t change the power cord, then your monitor must have a hardware failure.

The third case: colored lines appear on the monitor

In fact, to solve this problem, we must first know that there are two main reasons for the appearance of colored lines: First, if it is a full-screen colored line, or a colored line that appears with the change of the display content, usually their position is not fixed. , Generally does not fill up the entire screen, this situation is mostly caused by graphics card problems, such as overheated video memory or driver error.

The general approach is to reinstall and set up the graphics card driver. If the graphics card is overclocked, please reduce it back to the rated power. At the same time, clean the graphics card fan or heat sink and enhance the heat dissipation of the case.

Secondly, if it is one or more lines covering the entire screen, even if the displayed content changes, the position and color of the line do not change. The reason is mostly the problem of the control chip or cable of the LCD screen. Usually it can only be sent to the manufacturer for repair.

The fourth case: there are two vertical black bands on the edge of the display

This phenomenon mostly occurs on earlier computers, because the graphics card's video memory is not enough. The video memory of earlier computer graphics cards is only 1M. If the resolution is set too high, the above phenomenon will occur. To solve this problem, you can add video memory to the graphics card. Generally, there are sockets for adding video memory on this type of graphics card.
The fifth situation: the display screen shakes badly

The screen shakes so badly that sometimes even the icons and text are not clear, but it will return to normal after a minute or two. This phenomenon mostly occurs in humid weather because of moisture inside the display. To completely solve this problem, use the moisture-proof sand in the food packaging to string it with cotton thread, then open the back cover of the display, and hang the moisture-proof sand on the end of the tube neck of the picture tube near the tube base. In this way, even in humid weather, the above "problems" will no longer occur.
