My computer sometimes flickers twice when I use it?

It should be a problem with the connection line of the display,But it's not serious, it's not very good,If it's not very confusing to you, don't bother with pulling,If you mind,Then disassemble it yourself and plug it in,I'm afraid of a problem, then call more engineers who understand to help you pull (friends)。 There is also a possibility that the driver of your graphics card has been updated recently, if there is an update and this problem only occurs after the update, then it is highly recommended to change or your original graphics card driver, the new driver will sometimes be incompatible with your own computer, my computer is like this, you can change back to the old one. The one that suits you is the best.

Trouble, thanks!

1. It may be that the screen refresh rate is set too low, resulting in the inconsistency between the screen refresh speed and the refresh speed set by the graphics card.

In this case, you need to open Windows Settings, go to [System] - [Display] and click [Display Adapter Properties], and set the value to be the same as the graphics card in [Screen Refresh Rate] in [Monitor].

2. It may be that the computer graphics card driver is abnormal, resulting in the computer display screen stuck, flickering and other phenomena. This kind of green situation requires the use of third-party tools such as driver life, driver wizard and other third-party tools to reinstall the graphics card driver, and restart the computer after completing the installation to restore the normal screen display.

3. It may be that the computer graphics card chip is damaged (chip soldering, video memory burning, etc.). In this case, you need to apply for an after-sales service and replacement of the graphics card (if it is a laptop, the entire motherboard needs to be returned to the factory for repair, because the graphics card chip is soldered to the motherboard and cannot be independent).

DisplayBlack screenThe reason for the twinkle:

1. Display the refresh rate.

The settings are incorrect. 2. Graphics card driver.

The program is not installed or the version is outdated.

3. The display or connected power supply is damaged.

4. There are interference sources around.

Workaround:

1. Change the refresh rate of the monitor, the default refresh rate is 60, and change the value to 75 or more to solve the problem.

2. Install or update the graphics card driver, when the graphics card driver is missing or the version is backward, it will cause the graphics card to display an error, and the refresh rate change option is missing in the settings, etc., we need to check and install the latest version of the driver by ourselves.

3. Repair the display or replace the connected power supply, the damage of the display is the most important reason for the flickering of the display, due to the need to disassemble, you need to find a professional to repair, and the power supply problem can buy the same model of power cord to replace, the display line interface aging or accumulation of too much dust will also cause the display to flicker.

4. Clean up the surrounding environment of the monitor, if there is a strong magnetic field near the computer monitor, it will make the computer screen flicker and ripple, the solution is to put the computer in an open space or empty room without electronic equipment.

checked. It is also possible to restart the computer monitor, and the monitor will have an automatic demagnetization function during the switching process.

The monitor screen refresh rate is set too lowRight-click on the empty space on the desktop, click on the pop-up menu 'Screen Resolution' on the pop-up window, click on the pop-up window 'Advanced Settings' pop-up, and select a larger refresh rate in the drop-down box of 'Screen Refresh Rate'

1. Right-click on the empty space on the desktop, and click 'Screen Resolution' on the pop-up menu, as shown in the figure below

2. Click 'Advanced Settings' on the pop-up window, as shown in the figure below

3. In the pop-up window, click 'Monitor' at the top, as shown in the figure below

4. After opening, select a larger refresh rate in the drop-down box of 'Screen Refresh Rate', as shown in the figure below

The above method we talked about was tried first, and after checking the connection cable and interface of the graphics card and the display, to determine whether the contact is good. In fact, it is very simple, mainly to find 1, whether the connection is intact. The monitor should not be separated from the speaker magnetic object, and should be connected to it.

If there is a degaussing of the display 2, whether the power supply of the display is stable and the working state is normal. If it's normal, rule out the display problem 3、There's only the graphics card left.,I want to find the answer You change the graphics card and try it.,It's a graphics card problem if you change it or not.。
