Computer monitor shaking!! My LCD monitor keeps shaking, ask for help!

Neso's 786II, which my friend has used, is similar to the MAG796 FDII I used, both of which are diamond tubes, and the phone will not shake for an hour when I play next to it.

My monitors jittered in two situations, one time with two monitors back-to-back and the other with an inferior switch. The landlord can try to connect the monitor directly to the chassis.

The shaking I said is more powerful, the landlord said that it is normal to shake when it is refreshed at 75, but some people can't see how much they shake, indicating that people's eyes are different, and it is possible that the landlord's eyes are too powerful. Huh

Did the landlord try to change the power supply?,Your problem is really weird.,Your host uses this to shake.,Change it without shaking.,The monitor doesn't shake when used on others.。 Indissoluble.

It shows that everything is good.

Then I think it might be an interface issue

In addition, you put an iron plate on the left, right and back of the monitor, and the first situation I encountered last time was that I put an iron plate between the two monitors and didn't shake.

If there is no problem with the graphics card driver. You just adjust the refresh rate.

See if there is a problem with the graphics card drive.。。。 If there is no problem. That could be a problem with the display.

It is also possible that it is the interference of its electrical appliances. You can try your computer in a different place!!

Do you check whether the power cord of your monitor is not in good contact with the monitor, and when you send it for repair, is the power cord not taken, so you don't see it?

It's definitely not enough power from the power supply.

It's not that you come to me.

Feel free to use it!No problem !New monitors are like this!

It won't shake for a few days!

It just takes time to get used to the new environment!

Keep distracting objects such as stereos and cell phones away from them.

It's better to take the monitor and change it to another one. Just in case.

If there is no problem with the signal line, it may be caused by an out-of-sync switch signal from the display's driver board. When you set the resolution, one of the refresh rates is exactly within the synchronization range of the switching signal, so the image becomes stable. Sometimes the power supply filter capacitor becomes smaller.

To be on the safe side, you can try your monitor on another computer. If the phenomenon persists, it is better to send it for repair as soon as possible.

The problem with the signal cable of the display is that if you change to the DVI cable, it will not shake.

You shake along with it, and when you shake at the same frequency as the monitor, you don't feel it.

What brand of display If it is a miscellaneous brand, it will not be a problem with the line.

1.Observe the chip pins of the graphics card for rust. Rust can cause some pins to short slightly, causing the signal to output from the graphics card to be irregular or unstable.

Especially in the case of high relative humidity of the air, if it is not turned on every day or two, the impact will be more obvious;

2.The main control chip of the graphics card does not dissipate heat well, resulting in character jitter;

3.The mismatch between the video memory and the host speed causes character jitter;

4.There is magnetic field interference in the vicinity of the display. For example, magnetic objects such as ordinary speakers;

5.Signal attenuation of the display signal cable, such as poor contact between the signal cable and the graphics card, or squeezing or serious bending with other signal cables;

6.The unstable voltage waveform sent by the power supply causes character jitter, and the power supply is insufficient, the power supply load capacity is poor, the filtering is poor, the output ripple is too large, and the high-frequency AC interference is coupled to the display through the motherboard and graphics card, which will cause character jitter and other faults.

It can also be a cause of interference that is causing your LCD to shake. You first need to determine if it's because the LCD is automatically adjusting, and then try to move the main unit away from the LCD, some EMI (electromagnetic shielding) cases can cause such interference to the display, and of course the speaker or other electrical appliances should also be careful. Finally, there is the issue of data cables and interfaces, and the best thing to do is to connect your monitor to another host computer, which will help you find out what the problem is faster.

In addition to adjusting the refresh of the screen (usually 60 Hz) there is another easy way to teach you, because the current graphics card is too old for the current screen, you just need to turn down the display resolution. PS: My monitor has been adjusted to 1280x800

LCD (liquid crystal display) this situation is a common situation, I refer to small ripples, also known as water ripples, this problem is caused by many reasons, first determine the problems around you and then talk about it (LCD) problems, first rule out the following problems:

1.The quality of your signal cable is too poor, especially the requirements for LCD digital are very strict!

2.Your power supply has a bad EMI (a bad EMI will make the normal LCD water ripple).

3.The signal line is too long or there is a converter or something in the middle (which will reduce the strength of the signal).

4.Does your graphics card have the V frequency set (that is, the scanning frequency or something, generally set to 60Hz, the higher the frequency, the greater the water ripple. )

5.The above are ruled out, only to determine that it is the problem of LCD, and the professional genus is called: "interference".

6.Replace what should be replaced, repair what should be repaired, (replace the new one, repair the old one).

I am a master of this profession and LCD, if I am here, I will definitely show you.

If there is water ripple on the LCD display, find a maintenance person to repair it as soon as possible, and it will be miserable if it is late.

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.

If it's a driver problem, it's easy to solve, and use the driver wizard to update the driver. If there is a hardware problem, then the only way to repair it is to repair it.

Let me say two things, which are undoubtedly software and hardware problems. First of all, the software part,It's basically due to the driver is not suitable.,Or it's unstable.,The only way to solve it.,Go to the official website of the graphics card to find a stable version and install it.。

After the software problem is eliminated,It's a hardware problem,Hardware is divided into two parts,The first is the display itself,The second is the graphics card,Alternative method to solve it,Try to change the display to another host,Or change the other display to laugh on your host,It's easier to test the problem,But how to solve the problem has to go to the professional side to solve。

This problem: first reinstall the driver of the graphics card.

It's not good to dig aggressively, maybe the open core is the problem of the graphics card.

Under normal circumstances, the system can be solved.
