Remove the graphics driver and try to install it again.

Either it's the display aging failure.

Take a look at it.

Hope it helps.

First, the problem of display aging, you need to go to a professional testing center to test, to determine whether it is a display problem, you can directly connect the computer host to another monitor, if there is no flickering problem, it means that it is a display problem.

Second, the computer setting problem, the refresh rate of the computer resolution will also cause the computer to flicker. After the previous question, the test is not a display problem, then we test the resolution problem, adjust the resolution, and try to set it.

Third, the connection cable may lead to the output signal connection is poor, in such a situation, test it from a new wire.

Fourth, power supply or voltage problems, sometimes the power is not good, such as: rural areas, large factories, etc., resulting in voltage instability.

The specific steps are as follows:

1. Right-click on the empty spring auspicious white place on the desktop, and then click "Display Settings" (win7 can directly select the screen resolution);

2. In the display settings on the left, find and click "Advanced Display Settings";

3. Click "Display Adapter Properties--- Monitor ---Screen Refresh Rate Set to 60Hz" in turn, and finally click on the high annihilation.

When the computer has such a failure, you can plug this monitor into other computers for a period of time, if the cause of the splash screen still exists, then you can only find after-sales testing.

If there is no warranty period, it can be replaced free of charge, and it can be solved by going to the corresponding after-sales store. However, if the warranty period has passed, the cost of repair varies from tens to hundreds of yuan depending on the damaged part.

Maybe your monitor is magnetized, and generally magnetization is caused by the strong magnetic field around the display. Is there a stereo or other (such as electric fans, radios, high-power speakers, air conditioners and other household appliances) next to your monitor), because they may have a strong magnetic field around them, and strong magnetic fields have a strong destructive effect on hardware such as monitors and disks, it is recommended that you take away the electrical appliances with magnetic fields that are very close to the monitor, at least about 1 meter away from the display. Your monitor is flashing, and as for the solution, you can go to the repair computer and have a professional degauss your monitor.

In this case, it can also be that the picture tube of your display has been aged, under normal circumstances, do not adjust the brightness and contrast of the display to a very high level, generally the brightness can be set to 60-80, and the contrast can be set to 70-80, do not set the brightness and contrast to the highest with the standby and closed alignment, which may affect the service life of the display. However, adjusting the brightness and contrast should consider the protection of the eyes, and if you feel that it is good for the eyes, adjust the brightness and contrast ratio that suits you.

Another point,Maybe your monitor is set too high"Screen refresh rate",If you are using an LCD monitor, set the "screen refresh rate" to 60OK,If you are using a pure screen, set the "screen refresh rate" to 80. Don't set the "screen refresh rate" too high, as it may sometimes cause a black screen. For the specific steps of how to use "Screen Refresh Rate", right-click "Properties" on the desktop, open it, and then select "Settings-Advanced-Monitor", which has the option of "Screen Refresh Rate".

First of all, look at your screen resolution,Is it too high?,Zhengsong rent talk is often 1024*768,Then look at how much the color quality of your color is blind,Medium (16 bit),Highest (32 bits) You can adjust it down,Then click the "Advanced" button,See what your DPI setting is,It's generally normal,The most important thing is your screen refresh rate,I guess you're adjusting too high,Or too low。

I said a few points above, you can try it, I used to have a small flashing on my computer monitor, and then I had no problem with this debugging.

Note: All of the above is debugged in the display properties. How to get in: Right-click on the desktop and select Properties.

Your settings are not set properly, they are not the default settings of the monitor, so they will be adjusted automatically, but they are often unstable, causing the screen to flicker. You can press the auto button on the display screen to check the rent, he will automatically adjust it for you, and wait until all the default settings are restored, the display will be stable and will not flash carefully, I have encountered this kind of emotional failure once, and it will be fine to adjust it, not a big problem, not as serious as the upstairs said.
