My computer monitor keeps shaking up and down, what s going on?

It's obvious.

Voltage issues. You look at the people around your house who use a lot of electricity.

Electrical appliances?Like the oven.

Or high-power motors.

It is better to use a multimeter.

Take a look at the voltage.

The workaround is:

Buy a voltage regulator.

Okay, probably. Around 180-270.

Almost. 80 can come down, not on the desktop === right-click === properties ==== set --- advanced --- monitor.

This option. Change to 75 or 85

Heroes,Xiaodi's LCD recently found that the screen trembles,If the computer and the monitor are not turned on for a long time, it can remain normal for a period of time,But turn on the computer for about 1 hour and find that the display is shaking again,I don't know why。

At first, I thought it was a voltage problem.,But it's been a few days.,I think there's something wrong.,I hope you can help me.,My monitor is Sony's E76D resolution is 1280*1024 60Hz,I hope friends with the same experience can help me.。

Question added:I saw that there is no electromagnetic near my computer.,I also changed someone else's computer to try it or there is trembling.,I don't know why.,My computer was bought on August 3, 06.,It's my own group.,There's nothing wrong with other places.,Now there's something wrong with the monitor.。 It's a bit hot when the display is working, but I've asked all my classmates if the monitor is so hot.

Mine is a Shadow Spool Super Player graphics card.

The 60Hz frequency cannot be replaced.

Causes of display 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.

Many miscellaneous computer power supplies use the Yuan Biye parts workmanship and materials are very poor, which is easy to cause the computer's circuit to be poor or the power supply capacity can not keep up, 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 reinserting the graphics card, the fault can be troubled.

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

Such failures are generally due to the following reasons:

1.The graphics card is in poor contact with the signal cable of the display, and it should be reinstalled.

2.The monitor itself is faulty, and this requires the display to be replaced.
