Some friends may encounter this problem, that is, the computer flower screen, so what should I do when the computer flower screen? In fact, the method is relatively simple. Next, let me briefly introduce it to you!
The first case: the water ripple on the display flashes
The main cause of water ripple flicker of display is caused by wire, which can also be said to be one of the common problems. Generally, there are three kinds of cables used to connect the host to the display: VGA cable, DVI cable and HDMI cable. In addition, there is an uncommon DP cable. Except that DP line is quite expensive, the other three lines are relatively cheap, and most of the wire quality is trouble free. But if you still have a chance to catch up with inferior wire.
The second case: the display screen is black
The host has been running, other equipment has not failed, the display has been powered on, and the power indicator indicates standby, but the display is not on. If your monitor is black and the power indicator is not on, please check whether the power cord has been plugged in. If the power supply is sure to be plugged in, please replace the power cord. If you can't change the power cord, your monitor must be a hardware problem.
The third case: color lines appear on the display
In fact, to deal with this fault, we should first know that there are two main reasons for the occurrence of color lines: first, if it is a full screen color line, or a color line that appears with the transformation of display content, usually their position is not fixed and generally will not fill the whole screen. Most of this situation is caused by the failure of the graphics card, such as overheating of the graphics memory or driver error.
The general solution is to reinstall and set the graphics card driver. If the graphics card is overclocked, please also reduce the rated power, clean the graphics card fan or heat sink and strengthen the heat dissipation of the chassis.
Secondly, if it is one or more lines full of the whole screen, even if the displayed content changes, the position and color of the lines do not change with it. Most of the reasons are that the control chip or wiring of the LCD screen is faulty. Such faults can only be sent to the manufacturer for maintenance.
The fourth case: there are two vertical black bands at the edge of the display
This phenomenon mostly occurred in earlier computers, which is due to the insufficient video memory of the graphics card. The video memory of the earlier computer graphics card is only 1m. If the resolution is set too high, the above phenomenon will appear. To deal with this fault, you can add video memory to the graphics card. Generally, there will be a socket for adding video memory on this kind of graphics card.
The fifth case: the display screen shakes badly
The picture shakes so much that sometimes you can't even see the icon and text clearly, but it will return to normal after one or two minutes. The reason for this phenomenon is that the monitor is affected by damp weather. To completely deal with this fault, use the moisture-proof sand in the food package and string it with cotton thread, then run the back cover of the display and hang the moisture-proof sand near the tube seat at the tail of the tube neck of the display tube. In this way, even in wet weather, the above "problems" will not appear again.
The above is a summary of the reasons and solutions for the flower screen of the computer screen. If you encounter the problem of flower screen one day in the process of using the computer, you can solve it according to the above methods. If all the methods have been tried and still haven't been solved, maybe you should change the graphics card.
