Why Does My Monitor Make a Popping Sound?

Display monitors are an essential part of a computer system. Monitors are responsible for displaying computer-generated images, allowing users to interact with their PCs. Nowadays, display monitors are slim and have LED or LCD screens. But noise issues can also be found in these monitors.

In this article, we will try our best to explain why your monitor makes a popping sound occasionally. Not only that, but we will also provide you with solutions to eliminate these annoying popping noises coming out of your display monitor.

Why Does My Monitor Make a Popping Sound? Solved

Most of the time, your monitor makes a popping sound because of static electricity, a wrong refresh rate, short circuits, wrong display resolutions, overheating, a lack of power, faulty components, or loose cable connections. However, most of these issues can be resolved easily. 

Static electricity can build up on the surface of your monitor and cause it to make popping sounds. To get rid of this issue, you can use an antistatic spray or fabric softener on a cloth and gently wipe down the surface of your monitor. 

If the refresh rate of your monitor is too low, it can cause your monitor to make popping sounds. The refresh rate needs more power, but you will hear a popping sound if that power is insufficient. To fix this issue, you need to adjust your refresh rate in the display settings of your computer.

If sparking is inside your monitor, it might be caused by a faulty power inverter or UPS. A faulty UPS or inverter connected to your computer will be risky, as it won’t have any frequent current supply. However, you can replace the faulty component or take your monitor to a repair technician to solve this issue. 

If your display resolution is too low, it can cause your monitor to make popping sounds. To fix this, you need to change the resolution of your monitor in your computer’s display settings. 

Overheating might be the reason your monitor is making popping noises. This is because overheated components make different noises due to expansion. To get rid of this issue, you need to open up the casing of your monitor and replace any faulty components or clean up the dust and dirt inside it. 

Finally, it could be possible that there is a loose cable connection from the inside or outside connections. To solve this issue, you need to take your monitor to a technician and get it checked out.

Static Charge Present Inside The Monitor

Unplug your monitor’s power cable and press its power button for about 12 seconds. It is how you will complete an electronic circuit. As a result, the residual static charge stuck inside the charge-storing electronic components, such as capacitors and inductors, will be discharged soon.

After that, connect your monitor to AC voltage rather than UPS Inverter, Generator, or Surge Protector and switch it on. In the end, reset the factory settings of your monitor. Also, use a cotton cloth to clean the screen, as it will remove the screen charge.

Now, connect your monitor back to your computer. Hopefully, it will stop making popping sounds this time. But if the issue remains, check out our other suggestions before replacing your monitor with a new one.

Check The Refresh Rate of Your Monitor

The popping sound from your monitor can be because of a refresh rate other than the one recommended by your operating system. If you are using the Windows 10/11 operating system, then you can follow this procedure to check or change the refresh rate of your computer monitor:

  • Right-click on your Desktop and select “Display Settings” from the menu.
  • As you scroll down the right part of that window, a window will appear soon. There will be a blue title saying “Advanced display settings.”

  • In the “Advanced display settings,” you will see a default refresh rate. If it is not recommended, choose the one recommended by your operating system.

Sparking Inside The Monitor and Its Solution

One reason for popping sounds coming out of your monitor is the sparking. It might be the power cable of your display monitor or some loose or faulty parts inside your monitor. First, replace your monitor’s power cable and switch it on to check if it is still making the popping noise.

You don’t need to buy a new power cable for this experiment. Instead, just borrow it from your other display monitor for a minute. If changing the power cable solves the issue, get a new one for your display monitor.

The second reason for the sparking can be a loose or faulty component inside your display monitor. To find out, switch off the lights inside your room and look through the small spaces in your monitor case to see if there are sparks when the popping sound occurs. If there is a spark, you will need technical help from an experienced person.

Set The Display Resolution of Your Monitor to the Recommended One

The popping sound from your display monitor can be due to a resolution other than the one recommended by your operating system. If you are using the Windows 10/11 operating system, then you can follow these steps to check or change the resolution of your computer monitor:

  • Right-click on your Desktop and select “Display Settings” from the menu.
  • A window will pop up soon, and in its middle will be the display resolution, i.e., 1366×768 (Recommended).
  • You do not need to change your resolution if ” Recommended “ is written in the small braces. But if it is not, open the drop-down menu and select the one with the “Recommended” word in the front.

Faulty UPS Inverter with Wrong Output Frequency or Voltage Level

Old UPS inverters and generators lose their performance over time. Neither can they provide stable voltages of a certain level nor a certain output frequency. It is a built-in manufacturing fault for which some companies can be blamed. It may be possible that a UPS inverter or a generator imported from another country has different output voltage levels and frequency ranges.

We recommend you check your UPS inverter or generator to see if it has a fault or wrong voltage or frequency outputs. If the culprits behind the popping sounds coming out of your display monitor are the latter equipment, then change them immediately because they will damage your monitor and other electronic devices.  

Miscalibrated or Faulty Surge Protection Devices

Most of us use surge protector devices with our computer system to prevent them from burning out in case of lighting. These devices respond to the high and dangerous spikes of AC (Alternating Current) that keep generating for different reasons. 

However, miscalibrated or faulty surge protectors can harm your electronic devices because they do not switch off when the surge comes.

When purchasing a surge protector, ensure that a well-known company has manufactured it. It might be expensive, but will protect your devices in the long run. The second factor is the rating of surge protectors in joules. 

The higher the joule rating, the more the surge protector will be robust. The joule rating begins from 400 and ends at 2000 joules. By the way, a surge protector with a 1000+ joule rating is optimal for your device.

Overheating Monitor Giving Out Popping Noise

Overheating is a common cause for the display monitors to give out popping sounds occasionally. There are several reasons for overheating display monitors, such as dust, poor ventilation, and voltage fluctuations. If the reason behind the popping noise because of overheating is dust, then you want to clean your monitor properly from the inside with the help of a technical person.

On the other hand, if the root cause is voltage fluctuation, try to fix the issue first, as electronic devices can burn out in such fluctuation. Most of the time, the generators and UPS Inverters cause voltage fluctuations. So, wait until the AC power is on again to protect your precious devices, or switching to a better UPS inverter or generator should solve the issue.

There are small openings in every display monitor’s casingIf there are plastic wrappers around these openings or the monitor is placed in a narrow place with some cloth or books on its back, then this may be the cause of the popping noise. 

Try making some space around your display monitor, providing it a proper place so it can radiate its heat in the air. Then, hopefully, it will solve the popping sound issue on your monitor. 

Conclusion

We hope this article will help you solve the popping noise from your display monitor. However, there is no one-size-fits-all solution for fixing this issue. You may have to go through all of these steps one by one to find out which one was causing the problem in the first place. In any case, it is always advised to use quality equipment and check the wiring of your system regularly. That way, you can save yourself from many problems in the future.
