Win7 32-bit pure version of the system screen flicker and jitter how to do

First, check the computer around whether there is interference

Observe whether there is a strong electric field or strong magnetic field interference around the computer monitor, magnetic field interference is very easy to cause the computer screen jitter or flicker, the elimination method is to place the computer in another open space to observe, you can go to another place to take a good computer to test the exclusion, as far as possible not to the display near large electrical products. Can also restart the computer monitor to see, the general current display in the open process has automatic degaussing function.

　Second, check the display refresh rate set is correct

1, first in the Win7 32-bit pure version of the system desktop blank mouse right click to select "Properties" in the bounce out of the property interface click "Settings-Advanced";

2, in the bounce out of the interface to switch to the "Monitor" tab, you can see the display of the refresh frequency set to "60", which is causing the monitor screen constantly shake the reason. Set the new frequency to "75" and then click OK to return to the desktop.

　Third, check the video card driver is correct

Sometimes we go to the computer's monitor refresh frequency, but found that there is no refresh frequency to choose from, this is because the driver of the previous video card is incorrect or too old caused, then we can check and install the latest version of the driver.

　Quad, monitor hardware problems or power problems

Most of the hardware problems are encountered, for example, the monitor and the host connected to the data line, and so on, we can be replaced by the elimination of the method to solve, in addition to the monitor power only focus on the object, in the computer screen jitter encountered with the computer screen flicker of the fault, where the computer screen flashing most of the monitor power problem There are many is the display of aging, monitor failure, display jitter In addition to the magnetic field or electric field interference, the most encountered is the failure of the monitor aging, the solution is to take to a professional maintenance point repair. General new display can be taken to warranty or replacement, the new monitor due to hardware problems caused by the general very rare.
