Why does the screen keep shaking locally?

Causes of computer image shaking:

1. The screen refresh rate is too low; You can right-click on the blank space of the desktop, select 'Properties' (Win7 system selects 'Screen Resolution'), click 'Advanced Settings', select 'Monitor' in the pop-up window, and turn up the 'Screen Refresh Rate' to confirm (50-60 Hz for liquid display, 80 Hz for flat screen display).

3. The graphics card is loose; Disassemble the chassis and unplug the graphics card, clean the dust from the connector, and plug it back in.

4. The host-display connection cable is not in good contact; The desktop is disconnected and reinserted, tightening the fixing bolts; The notebook should be opened and reconnected and folded to be checked.

5. Most of the interference clutter or lines appear on the display screen, and there is noise in the speaker, which is mostly caused by the poor anti-interference of the power supply; It is possible to replace the display power supply with a new one. Or replace the filter capacitor in the power supply.

The power supply is unstable, or there is a source of interference nearby. If it's an external adapter, look at another adapter, and if it's directly connected to AC, take the screen to another place (where the other screens are normal) and try again. If it doesn't work, it will have to be repaired, usually because of the power supply.

1. The network signal is unstable.

2. The current generated on the surface of the screen.

3. The ROM of the brush does not match the mobile phone.

4. The radio baseband has not been upgraded.

5. Hardware problems, the mobile phone may be a refurbished machine, and the screen may be defective.

6. Wiring problems.

7. It is related to whether you use the original charge and whether the mobile phone screen is capacitive or resistive.

8. Mobile phone data problems.

Reason 1: The screen is damaged.

Solution: Whether the mobile phone screen has been dropped recently, it may cause the mobile phone screen to malfunction or the parts connected to the screen to be loose and faulty, and it should be repaired.

Reason 2: Electrostatic influence. Static electricity can occur during screen wiping or swiping quickly, which may affect the deflection of liquid crystal molecules within the screen, resulting in horizontal streaks, screen shaking, screen flickering, or color casts.

When the screen is not attached to the original protective film, the moment you quickly swipe the screen or remove the screen protector, the protective film is prone to static electricity due to material relations or dry environment, and there may be horizontal stripes, screen shaking, screen flickering or color cast. In the above cases, the phenomenon disappears when the static electricity dissipates.

Workaround: It is recommended to turn off the screen before wiping it with a clean, soft cloth or removing the screen protector.

Solution: If the boot screen shakes, and the screen returns to normal after a few minutes, you may be a victim of an inferior screen, and you should contact the dealer as soon as possible to return it.

Causes of monitor jitter:

The monitor refresh rate is set too low.

When the refresh rate of the display is set to be lower than 75Hz, the screen often shakes and flickers, so adjust the refresh rate appropriately, such as setting it higher than 85Hz, and the screen shaking will generally not appear again.

The power transformer is too close to the monitor and chassis.

When the power transformer is working, it will cause large electromagnetic interference, which will cause the screen to shake. Keeping the power transformer away from the chassis and display can solve the problem.

Inferior power supplies or power supply equipment are aging.

The workmanship and materials used in many miscellaneous computer power supplies are very poor, which can easily cause the circuits of the computer to be poor or the power supply capacity can not keep up, and when the system is busy, the display will especially appear screen shaking. When the power supply equipment of the computer starts to deteriorate, it is easy to cause the same problem.

The speakers are placed too close to the monitor.

The magnetic field effect of the speaker will interfere with the normal operation of the display, causing the display to produce magnetic interference phenomena such as screen shake and color crossing.

Viruses do the trick. Some computer viruses can disrupt the screen display, such as: character inversion, screen shaking, graphic flipping display, etc. The ubiquitous screen-shaking scripts on the Internet are enough to make your head as big as a cow after a hit.

The graphics card is not in good contact.

After the graphics card is reinserted, the fault can be troubleshooting.

Win95 98 system after write cache caused.

If this is the case, disabling all drive write-back caching in Control Panel - System - Performance - File System - Troubleshooter will resolve the problem at all.

The power filter capacitor is damaged.

If you open the case and see the top of the power filter capacitor (the largest capacitor on the board) bulging up, then the capacitor is broken, and the screen shake is caused by a power failure. Once the capacitor is replaced, the problem can be solved.

You also keep jittering, and when you jitter at the same frequency as the computer jitter, you don't feel the jitter of the computer anymore

There are a few reasons why the screen of the monitor keeps shaking:

1. The position of your monitor is not stable enough, especially for some general computer desks.

2. It's the problem of your monitor, the old-fashioned monitor, there is often a flicker screen problem, in this case, it is generally good to adjust to the maximum brightness.

3. The data cable of the monitor is not plugged in, resulting in unstable data.

Graphics card or display failure. In particular, it is possible that the high-voltage envelope of the graphics card is partially broken!

When you turn it on again, you close your eyes and rest for a while, and you can't see.
