My LCD is shaking?! Regarding the problem of computer LCD display shaking

I've also encountered this phenomenon you mentioned, and my solution is to change the refresh rate, and after changing it, it's normal.

Use the methods introduced above to check them one by one, and hopefully the monitor screen will never shake again!

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.

There are three possibilities:

1.Reinstall the graphics card driver.

2.Virus. 3.Display quality issues.

Is it a system problem? Try a different system.

Ghost version of the occasional problem!

1. Set the resolution and refresh rate of the display according to the recommended configuration of the monitor The resolution of the inch display is not the same, if you don't know, ask the service provider of the display.

2. Check the connection of the display data cable, it is best not to mix it with other cables, and be sure to separate them.

3. Restore the appearance settings of the display (in addition to the power switch on the monitor, there are many buttons, called OSD button, the general display provides the option to restore factory mode, try this function.) ）

4. Uninstall the existing graphics card driver and reinstall it once.

5. Make sure that the voltage is stable, and the voltage is unstable, just like flashing.

After the above points are ensured, the fault is still the same, and it is best to contact the corresponding service provider.

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 and solutions for the upper and lower shaking of the LCD screen:

1. 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.

2. 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.

3. Inferior power supply or power supply equipment has been aged.

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. Replacing the power supply or power supply unit can solve the problem.

4. The speaker is placed too close to the display.

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. Just put the speaker farther away.

5. Viruses are to blame.

Some computer viruses can disrupt the screen display, such as: character inversion, screen shaking, graphic flipping display, etc. It is necessary to kill the virus in time.

6. Poor contact of the graphics card.

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

7. Win95 98 system after write cache.

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.

8. 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.

2. Poor contact of the signal line will also attenuate the signal, check the connector and confirm that it is normal;

The TV picture is abnormal,There are many reasons,The common network cable interface is loose,Antenna interface is loose,There are parts inside the TV that are loose or damaged,It is also possible that the network signal is unstable,You should try the external interfaces that can be reinserted by yourself,If there is no change,It should be a problem with the TV itself,Then you can only find someone to fix it。

First: Update the graphics card driver and have a try.

Second: redo the system.

Third: If you can't do it, you have to congratulate you.

Because your graphics card is almost gone.

The screen shakes up and down, which generally appears after a while of booting, and the main fault location is:

1. The refresh rate of the LCD is set improperly;

2. The filter circuit of the LCD part of the power supply is damaged;

3. There is a problem with the graphics card;

Exactly which part requires further examination to know;

It is recommended that the landlord send it for repair.

The graphics card is no problem, but the display is about to return to the West! ......Congratulations!

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

It seems that it is a problem with your monitor hardware, go to a professional repair station to test your monitor.

I think it's a matter of frequency, adjust it lower and see.

Upstairs, isn't the LCD screen just the LCD screen? I thought I was wrong.

Because the signal sent by the host graphics card to the LCD screen has to go through the interface circuit, the miscellaneous LCD uses inferior components in the interface in order to reduce the cost, which distorts the signal transmission, that is, the signal phase is different from that of the graphics card, so that when the display content changes greatly, the image is unstable, and this problem cannot be solved by the individual, so it can only be sent for repair.

LCD screen is now basically obsolete, and the selling price in the second-hand market (17-19 inches)** is generally between 80-130.

Right. You read that right, it's between 80-130 yuan RMB, sell yours, and add a few dozen yuan for one.

It's really not possible to change the LCD, the LCD is very cheap now. You can buy a very good one for about 800 yuan

It shouldn't be a problem with speakers,Because first,The current speakers have a non-interference design,Basically it won't affect the display,Unless it's a very old speaker。 Second, speaker interference only works for CRT displays, and is useless for current LCDs. Immunity, the principle is different.

As for jitter, you try the refresh rate first. If the refresh rate is too high or too low, the image will shake or flicker.

See if the interface is in poor contact. If possible, plug the monitor into the normal host to see if it is a monitor or a host problem.

If it doesn't work, it's only to send it for repair. It doesn't seem to cost anything to test.

Good luck.

Look at whether your speaker is too noisy,Another point is that you set the best resolution,Solution,There is an automatic adjustment function on the monitor,You will return to the best state if you grope it yourself。

Maybe it's a drive issue, maybe it's a signal line compatibility issue.

It is recommended that you try to change the DVI cable first, and do not use an adapter.

If it doesn't solve the problem, reinstall the graphics card driver (uninstall it and reinstall it) to see if it solves the problem.

I think it's best for you to change the DVI line no matter what, both from a problem solving point of view and from a visual perception point of view,。。

It would be nice to change the data cable.

Unlike CRT displays, LCD displays are not subject to external electromagnetic interference. In this case, in addition to the problem of the graphics card, it is possible that the LCD has not been correctly switched to the corresponding display resolution, because the display has different terminal matching resistors for different display levels, and if this is incorrect, the signal will be reflected and the picture will shake. First of all, unplug the cable connecting the monitor to the chassis, insert it carefully, and tighten the screws, if the problem is still not solved, please find a professional to send it for repair.

The high-voltage pack of the display is also the capacitance of the graphics card. You can fix it!

A little suggestion!

The graphics card is going to break! You can modify the separation rate and try it again.
