Win8 notebook screen jitter solution

The Win8 notebook screen flickers slightly, even shaking up and down. This may be a problem with the graphics card, you can try to reinstall the graphics driver first. Here's a look at the causes and solutions for Win8 notebook screen jitter.

Reasons for notebook screen jitter:

1. Poor contact and signal interference;

2. Screen refresh rate is too low and graphics driver;

3, poor quality power;

4, hardware problems.

The bottom of the computer screen flashes, the black screen, the computer screen shakes, in addition to making you feel that the eyes are quickly fatigued, and the long time will bring the eye disease to the user. If it is not resolved in time, it will cause damage to your system, because the hidden problems of the system itself may be reflected in the phenomenon of screen jitter. In fact, there are many reasons why the screen may appear to be jittery. In fact, it is not so difficult to solve.

Solution laptop screen jitter:

One: Jiechubuliang problem

and take a look at the host monitor's power lines are not connected steady, if relatively loose This splash screen will appear.

2: Signal interference problem

There is no shield coil on the cable connected to the monitor. If there is no black bump on the anti-interference, it will also interfere with the screen. Also check for interference nearby, such as high-power audio and power transformers.

Monitors are susceptible to strong electric or strong magnetic fields, and sometimes screen jitter is caused by magnetic or electric fields near the display. In order to eliminate all the interference around the monitor, you can move the computer to a table that is all around, and then start the test. If the jitter of the screen disappears, it means that there is a strong electric field or strong magnetic field interference in the original place of your computer. Please take suspicious things (such as the speaker's subwoofer, magnetized cup, etc.) from the computer nearby. Then turn off the display and re-open it a few times to achieve degaussing (the current display has automatic degaussing when turned on).

Three: Screen refresh rate problem

Right click on the desktop -> Properties -> Settings -> Advanced -> Monitor -> Screen refresh rate, CRT adjusted to 75Hz or above (Notebook The LCD screen of the computer can be adjusted to 60Hz.)

In fact, the main reason for the monitor screen jitter is that the display refresh rate is lower than 75Hz. At this time, the screen often appears jittery and flickering. We only need to increase the refresh rate to above 75Hz. The phenomenon of computer screen jitter will not appear again.

Four: The graphics card driver is not correct

Check if your graphics card is loose. Try uninstalling the computer's graphics driver and installing a stable version of the driver.

Sometimes when we enter the computer's display refresh rate, we find that there is no refresh rate to choose from, which is caused by the incorrect or too old driver of the front graphics card. Computers with earlier purchase time are prone to this problem. Do not use the driver on the CD that came with the computer when you purchased the computer. You can download the latest version of the driver card on the Internet and open the Properties window of the system. Click the “Device Manager” button in the “Hardware” window to enter the device list interface of the system. Right-click the display card option in the interface, click the “Properties” command from the pop-up menu, and then click the “Driver” tab in the pop-up card property settings window. Click the “Update Driver” button on the corresponding tab page, and then gradually update the graphics card driver to the latest version according to the wizard prompts. Finally, restart the computer system. If the driver is installed properly, the display refresh frequency selection will appear. Item, and then set the refresh rate to 75Hz or more to solve the computer screen flicker.

Five: Restore the BIOS to the factory settings, plug in the memory and graphics card, and reinstall the full version of the operating system.

Six: Inferior power or power supply equipment has been aging

Many of the components used in computer power supply are poor in workmanship and materials, which may cause the computer's circuit to be poor or the power supply capacity to keep up. When the system is busy, the display will especially appear on the monitor screen. The power supply must be replaced at this time.

Seven: Finally, consider hardware issues such as monitors and graphics cards.

Sometimes, the display used is too high, and jitter will occur. In order to verify that the electronic components inside the display are aging, the faulty display can be connected to someone else's computer for testing. If the fault still disappears, the display is broken and needs to be repaired.

Eight: Viruses

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

Add some basic knowledge of LCD monitors:

LCD monitors sometimes adjust images automatically, especially if you reinstall the system or use a one-click restore system, if you do not adjust in time The resolution and refresh rate, the LCD will automatically adjust the image, this is we will see the screen flashing, in general, the refresh rate can not be adjusted up, the increase will increase the computer hardware The load is not good for the hardware, especially the graphics card.

The above is the solution for Win8 notebook screen jitter, of course, the graphics card driver is still the main cause of screen jitter, if reinstalling the graphics card can not solve the problem of screen jitter, try other methods.
