First, adjust the display frequency of the display.

When our monitor shows a low frequency, the computer screen flashes and the computer screen jitter is most likely to occur. We can check our own computer monitor display frequency: Right mouse click on the computer desktop space and then select the properties-Settings-advanced option, as shown in the picture:

Then switch to the Monitor tab, as shown in the figure: If your monitor shows a frequency of 60 hertz or less than 75 hertz, there is a possibility that the computer screen flashes and the computer screen wobble, so we increase the display frequency by 75-85 Hertz. Nor is the higher the better, too high the display life will be shortened, or overclocking the display will be black screen, as can not be displayed. Some laptops have only 60HZ of this value, so there is no need to set.

Second, the driver of the graphics card problem.

If we change the display frequency is found not to choose (generally 5 for the size of the increase or decrease) or change the digital computer display has not changed, that may be due to a problem with the graphics driver or a low version, so that we can download the video card corresponding to the new driver or automatic check update.

Third, whether it is outside interference.

As we all know, the display is also a lot of electronic components, in a strong magnetic field or the interference of the electric field will surge to normal work, it may cause the display flicker or jitter, we can put the computer to the surrounding without strong electric field, magnetic field test under the environment.

Quad, monitor fault, power cord, data cable connection problem.

If the above method can not solve your problem then may be the monitor power supply, signal line problems, or the monitor is broken, then we can reconnect the power cord, and monitor and host connected to the data line, to ensure that the connection is normal, moreover is the display time too long, internal electronic components fault.
