Ask for help, big guy! What should I do if this monitor keeps shaking?,It s every 3 seconds.,I can t

Judging from this**--- it should be entirely a problem with the display. It is estimated that a component on the circuit board has deteriorated. Just send it for repair.

The most common is the capacitor bulge. If you are an electronics enthusiast, you can also take it apart and check it yourself--- safety first! Remember to unplug it first!

That's all there are a few possibilities:

1) If the signal cable is in poor contact--- remove the signal cable and reconnect it;

2) The quality of the signal line is too poor (no shield) - replace the signal line;

3) If the graphics card fails --- the discrete graphics card, replace the graphics card, and add a discrete graphics card to solve the problem if the graphics card is integrated.

This kind of estimation is a problem with the picture tube,It's good to have to change a picture tube estimate,At the time, I just looked at this phenomenon and thought it was,Specifically, I still have to repair the computer and let them test it,It should be a hardware problem,You have to repair it or change a part,It's not caused by software,It shouldn't be a big problem,It is estimated that it can be repaired if you take the repair TV。

The problem of this situation in the display is generally in the display itself, **connection cable, graphics card, first check whether the **cable is connected or try to change the strip, if there is no problem, replace the graphics card or connect the monitor to other computers, if the problem still exists, then it must be the fault of the display itself.

First of all, check the interface of the connector to see if the connection port of the display is loose. Then restart it once and see if the computer can fix it automatically. If the external interfaces are all good, consider that the internal picture tube is broken, or that some other component is damaged.

It is recommended to send it to the maintenance point for professional maintenance in time.

This phenomenon is that the display is broken, as if the capacitance of the power supply part of the display is broken, or the capacitance of the video discharge power supply is broken.

See if there is a problem with the power supply, and if it is normal, then you need to change the computer monitor.

This is directly the damage to the display, and the damage to its control components. The software can't handle it.

Replug those plug wires back in, or see if there's any oxidation?

Use the methods introduced above to check them one by one, and I believe that the monitor screen will never shake again.

I don't know what kind of jitter you mean by "shaking"?

Make sure it's the monitor that's wrong.

If it flashes brightly and dimly, it means that the lamp is not working, the lamp is cheap, and it can be done for dozens of dollars.

If the desktop content on the screen is shaky, it means that there is a problem with the high-voltage board. The most likely is that the components on the high-voltage board are aging, because the temperature rises one hour after start-up, and the changes in the surrounding environment make the aging components work unstable. For example, the capacitor filter is unstable, and the resistance value becomes larger.

Pin travel key. High-voltage board: Open the LCD back cover, remove the shielding cover, there are two PCB boards below, one of which is connected to an external power supply, which is a high-voltage board; The other piece with a cable connected to the screen is the driver board.

Supplementary reply: The monitor has been replaced by someone else's electric ballast, and the brain is shaking, of course, it must be the problem of the display itself. Your monitor is still within the warranty period, hurry up and take the warranty, it must be a coincidence that there is a problem with the high-voltage board.

There are three reasons for the display screen shaking: First, the display refresh rate is set too low, when the screen refresh rate is lower than 75Hz, the picture will shake and flicker. If this is the case, you can increase the refresh rate appropriately, such as 85Hz or higher.

The second is other equipment (such as scanners, ADSL

modem) The power transformer (or adapter) is too close to the display. Because the power transformer will produce large electromagnetic interference when working, resulting in image shaking. Placing the power transformer far away from the display will solve the problem.

The third is that the inferior power supply or power supply equipment begins to age. Many miscellaneous chassis power supply internal components are very poor, easy to cause PC circuit is not smooth or power supply capacity can not keep up, when the system is busy, the display will appear screen shake phenomenon, then you can replace the power supply or power supply equipment to try.

You shake with the screen of the monitor, and when the frequency of your shake is the same as the picture of the monitor, you will find that the monitor does not shake.

If the graphics card driver is installed, if it is installed, adjust the resolution to 75Hz or above.

Are you a desktop monitor or an LCD monitor wow-

If it's desktop. There is a degaussing button on it.

If it's LCD, you need to see if there's anything magnetic next to your monitor that's interfering.

If you have tried to degauss, you can only see if there is anything magnetic next to you that is interfering, that is, your monitor is broken. Aging.

Let's see if I can do it!

You can shake with the monitor at the same time and at the same frequency. According to the theory of relativity, the picture you see is stationary.

Is it an LCD monitor?

In the case of liquid crystal, this situation is relatively common.

First of all, don't put electronic products such as mobile phones or speakers next to the monitor.

You can also try moving the cable that connects the monitor to the graphics card.

Especially on the line on this side of the monitor socket.

Move around to see if anything changes.

If it doesn't work again.

Take the monitor to the dealer.

Let's see if it's a layout issue.

If there is a problem, it will be reversed.

Right-click on the desktop.

Select Properties. Inside the settings.

There's a premium in there.

There's a monitor inside the advanced.

If you change the refresh rate to 85hz or above (as long as your monitor supports it), usually around 75 will solve the problem.

Maybe it's 60 when you open it.

Adjust the refresh rate above 75Hz, it won't, but there is another reason, it is related to the magnetic field, if you get too close to the amplifier or voltage regulator and other equipment, it will also produce screen jitter, and then there is the display can not reach 75Hz

Right-click on Properties - Appearance - in an empty space on the desktop"Advanced"- > monitor "- screen refresh rate" set to 75 Hz to see, if not, change to a different frequency to see.

The phenomenon you are talking about is typical of magnetization.

There are many reasons for this, 1 First of all, do you see if there are high-power appliances next to the display?

2Is your monitor placed against a wall? Stay away from the wall appropriately.

3Do you have unshielded wires on the wall behind your monitor?

4. Is it connected to other electrical appliances, such as air conditioners, on the same live wire (within 5 meters) as your monitor power supply?

5. There is also a possibility that there is a problem with the degaussing coil in the display, which needs to be disassembled and repaired.

Generally speaking, magnetization is mainly caused by strong magnetic interference in the vicinity, which can be caused by the work of other electrical appliances or the room is too small.

I suggest you move the monitor to another place to try it first, if there is still ripple, it means that the display degaussing coil is faulty;

If it's normal elsewhere, it means that the magnetic field in your room is too disturbant.

Not a less noticeable jitter?

That requires adjusting the refresh rate of the display.

Control Panel displays the Settings > Advanced monitor.

The screen refresh rate is adjusted to about 75Hz.

When the screen refresh rate is low, it will feel shaky.

There are many possibilities, so try it patiently.

1.The refresh rate is not adjusted properly. Desktop (right-click) - Properties - Settings - Advanced - Monitor refresh rate is in that tone.

2.If there is a problem with the memory, find another memory to try.

3.If there is a problem with the power supply, try it with a different power supply.

4.Disturbed by electricity. (Change places, huh!! Generally at home, this is rare.

5.Problems with the motherboard. It may be that the heat dissipation of the Northbridge chip is not good enough, if it is really like this, it will be troublesome.

6.It could also be that there really is something wrong with the display. It may be that the connector is not connected well or the wire is twisted, you plug and unplug it a few more times, and get the cable right, or if this is the case, it may be bad, then you have to take the monitor to find a professional.

Right-click on the desktop, select Properties, Settings, and then Click"Advanced"

There's a monitor inside, adjust the frequency of your monitor, and you're good to go.

The display frequency of the monitor is not adjusted well, it is recommended: CRT 75Hz LCD 60Hz

Check whether the power supply of the monitor is OK and whether the transformer is OK.

Finally, determine whether the voltage in your area is unstable.

There is a slight jitter, first of all, you make sure that the distance between the computer in your speaker is not enough, and there is nothing magnetic around the graphics card, exclude these, if it is still like this, it is recommended that you send it for repair.

I don't know if you have installed the graphics card driver, I also have this problem after changing the graphics card. Although the driver-built by Windows can drive most graphics cards, I think it's better to have a dedicated driver. For example, after I installed a new driver, it was good to adjust the refresh rate to 70Hz, and there was no similar phenomenon.

Click on the desktop right to see the properties - there is an advanced option inside the settings - the monitor screen refresh rate is set to 75hz or higher.

It's a CRT flat bar that sets the refresh rate to 75 or above. If the LCD presses the auto button to adjust it automatically, it would be good. If it's still not good, please change the monitor.

Then you don't stop.

Jitter when you jitter at the frequency and amplitude.

When it's the same as the monitor, then you won't feel shaky.

First of all, check that your monitor has been adjusted to the optimal refresh rate (usually 85MHz).

Second, check that your graphics card driver is installed correctly :)

There are many kinds of jitter, depending on which one you are. 1 is the display quality problem,2 is to look at the refresh rate of your monitor to see what it is,Change the refresh rate to try,3 is the power supply problem,There are power supply problems and motherboard problems,Some motherboards are not well supplied with power,Adding memory or something will affect the power supply of the graphics card and then cause the picture to shake,4 is the surrounding environment,See what high-power electrical appliances are around,The high-power electrical appliances are too close to the computer will affect the picture,Especially the CRT display,The impact is greater。

The computer screen is shaky because the monitor accessories have something to interfere with, the most common being the speaker. Cell phones and so on.

You also don't shake constantly, and when your frequency and amplitude are consistent with the monitor's picture, you won't feel it.

Do you shake without moving?

If it's yours the refresh is too slow.

Also, maybe your graphics card is not driving the right one.

The easiest way is to move your head with the computer's frequency, so that you won't feel the display jittery when you reach the same frequency.

Screen flickering glitch.

If the resolution and refresh rate of the monitor are set too high or too low, this kind of failure can also be caused, so you can try setting the resolution and refresh rate to the middle (note: long-term overclocking will cause some components to age and cause this failure, and the fault point is difficult to find). There is also a bug in the driver of the graphics card or monitor, so you need to update the driver first.

If none of the above fails, it is important to check whether the acceleration pole voltage and high voltage generated by the high-voltage packet are normal, because sometimes these two voltage anomalies can also cause such phenomena. Note: If the TV is flickering when you turn it on, then you must first check whether there is a problem with the mains power supply - such as the capacity is too small or the voltage fluctuation is too large (it is best to find an electrician to check).

Sometimes some magnetic items (such as some low-grade power boxes or ADSL external cat power supplies, etc.) placed near the display will cause a certain corner of the screen to flicker, so when encountering this phenomenon, try to clear the items around the display first, and usually the problem can be solved.

Your head is also constantly shaking slightly, and you won't feel the image shaking when your head shakes at the same frequency as the monitor screen. This way the problem can be easily solved. Of course, if you don't believe Brother Chun, you may be a little dizzy if you keep shaking your head.

You can try to keep shaking your body as well, keeping it in the same line as your head. That way, you won't get tired. I hope you find it useful.

Is the refresh rate setting too low?

Here's how to give it a try.

Right-click on the desktop--- Properties--- set --- advanced --- monitor --- screen refresh rate (choose a higher frequency, but not too high, if your computer supports it, choose around 80 Hz).

If yours is a normal monitor, right-click on the ->> properties in the blank space of the desktop.

In the pop-up dialog box, click Settings -> Advanced, there is a monitor option in it, change the refresh rate of the monitor, generally 75 or more,
