Win8 System Notebook screen jitter how to solve

Win8 System Notebook screen jitter how to solve

Failure Reason:

1, contact bad and signal interference category;

2, screen refresh frequency is too low and graphics driver;

3, inferior power supply;

4, hardware problems.

computer screen flashing, black screen, computer screen jitter, in addition to make you feel the eyes will soon fatigue, long time will bring to the user eye disease. 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.

Workaround:

One: Bad contact problems

First look at the host and monitor power cable is not stable, if relatively loose will appear this splash screen.

Second: Signal interference problem

The cable that connects the monitor has no shielding coil, and if there is no interference, the black bump will also interfere with the screen. Also check nearby whether there is interference, such as high-power audio, power transformers.

Monitors are susceptible to strong or strong magnetic fields, and at some point 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).

Third: The screen refresh rate problem

Desktop Right-click-"Properties-" Settings-"advanced-" Monitor-"screen refresh frequency, CRT adjustment to 75Hz or above (laptop LCD screen LCD to 60Hz).

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 up to 75Hz above, then the computer screen jitter phenomenon will not appear again.

Four: The video card driver is not correct

Check to see if your video card is loose, try to uninstall the computer's graphics driver and install a stable version of the drive.

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 pop-up right-click menu, click the Driver tab in the pop-up Graphics Properties Settings window, click the Update Driver button in the corresponding tab page, and then update the video driver to the latest version, as prompted by the wizard. Finally, the computer system restarted a bit, if the driver installation is appropriate, the display will appear refresh frequency selection, and then set the refresh rate of more than 75Hz to solve the computer screen flashing.

V: Restore the BIOS for factory settings, plug the memory and video card, reinstall the full version of the operating system.

VI: Poor quality power 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 computer screen jitter. The power supply must be replaced at this time.

Seven: The final consideration of the display, graphics and other hardware problems

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.

Eight: Virus Mischief

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

Supplement the basics of some liquid crystal displays:

The liquid crystal display sometimes adjusts the image automatically, especially when you reload the system or use a key to restore the system, if you do not adjust the resolution and refresh rate in time, the LCD will automatically adjust the image, this is we will see the screen flash flash, under normal circumstances, the refresh rate can not be casually adjusted high, The increase in the computer hardware will increase the load on the hardware is not good, especially the graphics card.
