The monitor has been on for a long time, and the screen is always shaking badly 5

Causes of display jitter.

The monitor refresh rate is set too low.

When the display of the Delphant Eater Rose? At 5Hz, the screen often shakes and flickers, and the refresh rate is appropriately increased, such as setting it higher than 85Hz, and the screen shake 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 shake 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.

Open the case, and if you 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.

The heroes upstairs do have a point, but they can't rule out the possibility of a computer virus, if it's not for hardware reasons, it is recommended to use antivirus software to scan it.

I once had a similar situation, and then I found out that I was hit by a Trojan horse program, and there was no problem after deleting it!

Good luck!

Ha, don't ask, there is a problem with the monitor, if your monitor is still under warranty, I suggest you replace it, if it is not under warranty, then I suggest you repair it!

Is there something next to the computer that can generate a strong magnetic field? Like speakers?

If so, then demagnetize!

If that doesn't work, then go and fix the monitor, presumably because there's something wrong with the CRT.

You're a CRT, the CRT is aging, let's get another one

It is highly recommended to degauss, the landlord said that it has been open for a long time.

It is estimated that there is a strong magnetic field around, or it will not be the case with the new one.

If you have a problem with your management, you can fix it for about 30 yuan.

Degauss or fix it

84628421's very comprehensive, I think you should also try to eliminate the magnetism first! Button under the display!

Like me, we ...... share the same disease

Here's how to solve the problem:

1. Electromagnetic interference. The most common possibility is that the laptop will shake when it is connected to the power supply, and it will be fine if it is not connected to the power supply. Only one power adapter needs to be replaced.

2. The impact of electricity consumption. In this case, it is caused by connecting to the socket of the computer by connecting to high-power electrical equipment such as boiling water for cooking or washing machines. This is very simple, you don't need to connect these high-power electrical equipment.

3. Influence of magnetic field. If your speaker power is large and the anti-magnetic function is weak, it is more likely to occur when placed next to the monitor. At this point, just remove the magnetic material from your computer.

4. The resolution is wrong. It is also common for the display to have unsupported resolutions, resulting in this problem. In general, you just need to change back to the correct resolution.

5. Graphics card problems. If you're using a desktop computer and you're using a discrete graphics card, a loose or damaged graphics card can cause the screen to shake. At this point, you just need to plug in or replace the graphics card.

6. Problems with the host itself. On inferior chassis, the host cause cannot be ignored, and the wiring is not good to guide interference.

7. Connection line problem. Inferior cables are not shielded and are highly susceptible to power cord accessories, and even if they don't, the inferior cable itself can cause this problem. At this point, it's good to replace the cable.

8. Display aging. This is the last thing you want, but if none of the above methods can be solved, you should check whether the display is aging. Then just replace the monitor.

After the monitor is turned on, the screen shakes. This may be due to the following reasons.

1.When the transformer of the power supply is working, it generates relatively large electromagnetic interference, resulting in screen jitter. Place the power transformer away from the chassis and display. place, you can solve the problem.

2.If the refresh rate is not set properly, adjust it again until the screen returns to normal.

3.Inferior power supply or aging power supply equipment. The components used in miscellaneous power supplies are very poor in workmanship and materials, resulting in poor computer circuits or power supply capabilities.

4.The monitor is too close to the speaker. Audio can interfere with the display, causing the display to shake and color.

5.Viruses disrupt the screen display. Such as character inversion, screen shaking, image flipping, etc.

6.The filter capacitor of the power supply is damaged. If you see the top of the power filter capacitor bulging, it means that the capacitor is broken, and the capacitor can be replaced. ;

Adjust your screen's hertz value below 70 Hz and you'll have no problem.

There's nothing wrong with your graphics card. Let's take a look at the monitor first. Then there's the issue of your VGA signal cable. Take a look at the original one. Some miscellaneous displays are not displayed with ordinary signal cables.
