Solution to computer screen jitter

The display screen constantly shakes, in addition to make you feel the eyes will soon fatigue, long time will bring the eye disease to the user. If not resolved in a timely manner will cause damage to your system, because the system itself may be hidden problems reflected in the screen jitter phenomenon. In fact, there are many reasons can cause the screen jitter phenomenon, in fact, it is not so difficult to solve.

According to the form of computer screen jitter can be divided into, computer screen jitter, computer screen jitter, the principle of general jitter is the same, computer screen jitter solution can refer to the following analysis reasons:

　　First, the display refresh rate is not set correctly

If the refresh rate setting is too low, it will cause the screen to wobble, check the blank area of the system desktop with the right mouse button, click Properties from the right menu of Dan, and go to the Properties Settings window of the monitor. Click the Settings tab in the window, in subsequent Dan out of the corresponding label page, click the "Advanced" button, open the advanced properties of the monitor settings interface, and then click the "Jian" tab, where you can see the display's refresh rate 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.

In fact, monitor screen jitter is the main reason is the display of the refresh rate is less than 75Hz, at this time the screen will often appear jitter, flashing phenomenon, we simply adjust the refresh rate to more than 75Hz, then the screen jitter phenomenon will not appear again.

　　Second, the graphics card driver is not correct

Sometimes when we go into the computer's monitor refresh rate, we find that there is no refresh rate to choose from, because the driver of the previous video card is incorrect or too old. It's easy to get this problem on a computer that has an earlier purchase time at this point do not use the purchase of the computer with the CD-ROM driver, you can download the corresponding display card of the latest version of the driver, and then open the "System" Properties window, click the "Hardware" window of the Device Manager button to enter the system's device list interface. Right-click the display card option in the interface, click Properties from the right-click menu in Dan, and then click the Driver tab in the Card Properties Settings window for Dan, and then click the Update Driver button on the corresponding tab page. After the wizard prompts Step-by-step to update the graphics driver to the latest version, and finally the computer system restarted a bit, if the driver installation is appropriate, the display will appear refresh frequency options, and then set the refresh rate to more than 75Hz.

　　Third, the magnetic field interference caused the display jitter

Monitors are susceptible to strong or strong magnetic fields, and if the two methods described above still do not resolve the jitter problem, it should be suspected that the screen jitter is caused by a magnetic field or an electric field near the monitor. In order to remove all interference from the perimeter of the monitor, you can move the computer to a table around the empty, and then the power-on test, if the phenomenon of screen jitter disappears, then your computer where the original place has a strong electric field or strong magnetic field interference, please suspicious things (such as speakers of the subwoofer, magnetized cups, etc.) From the computer near the good. Then turn off the monitor and reopen it a few times to achieve the purpose of degaussing (the current display has an automatic degaussing function when it is turned on).

　　Four, the display card contact bad

Open the chassis and pull the display card out of the slot. Then hand will show Kakin fingers of dust wiped clean, it is best to find soft hair brush, gently the graphics card surface of the dust all clear clean, and then use a clean eraser on the surface of the gold finger wiped a few, to clear the gold finger surface of the oxide layer, Finally, reseat the display card tightly into the motherboard slot and fasten it to the chassis shell with screws. Then the boot test, the general failure can be resolved.

　　Five, monitor aging

Sometimes jitter can occur because of the high age of the monitor used. In order to verify the aging of the electronic components inside the display, the faulty monitor can be connected to someone else's computer for testing, if the fault still disappears, the monitor is bad and needs to be repaired.

　　Low-quality power supply or power equipment has been aging

Many of the computer power use of the components of the work, materials are very poor, easy to cause the computer circuit is not smooth or power supply ability to keep up, when the system is busy, the monitor will appear in particular the phenomenon of screen jitter. When the computer's power device starts to age, it is also easy to create the same problem. The power supply can be replaced for testing at this time.

　　Seven, the virus mischief

Some computer viruses will disturb the screen display, such as: character inversion, screen jitter, graphics flip display.
