The high pitched noise from many LCD monitors when their brightness is reduced can be utterly distracting. Here’s a simple workaround that can work quite well with most monitors for many users. Also, please participate in our Quiet / Noisy Monitor Survey!
Many computer users have run into the issue of whining LCD monitors. Usually, it does not occur when the monitor is set to full brightness, which is usually too bright for most users. The natural response is to turn the brightness down using the monitor’s controls. That’s when the monitor can start to emit some high frequency tones, which are described most often as buzzing or whining. The noise usually gets worse the more the screen is dimmed.
It can be piercing and annoying enough to overcome even relatively high ambient noise. If you’ve spent the time and effort to study the information on SPCR and managed to achieve super-quiet performance in your computer, this whine can be absolutely frustrating. In short, it can drive people crazy.
The noise that is coming out of my laptop is not so fluent (more like you hear it really short several times after eachother). Like you are clearing your throat but then high pitched and not so loud. I first noticed it when i was downloading a game. If your Windows 10 computer only makes buzzing noises when you play audio on it, this solution is definitely worth trying out. To disable audio enhancements for your computer’s speakers, you need to: Open the Start Menu. Type Sound into the Search. Click on the search result titled Sound that appears under Control Panel. Dec 30, 2008. Machine makes a high-pitched whining sound when attempting to print from a computer Typically, the whining noise is a result of slow printing caused by the machine waiting for the data to be processed.
Refrigerators can be noisy (clicking, buzzing, humming, high pitched squeaks) and some sounds are just a normal process of refrigeration. Sometimes a refrigerator will develop a problem and a high pitched noise can be heard. To fix this issue you must determine the source of the sound. By doing so you can locate the problem How To Fix A Refrigerator Making High Pitched Noise Read More ».
The source of the problem appears to be components in the electronic circuit which controls the brightness of the CFL bulb that lights most LCD monitors. Most likely, this is some form of PWM (pulse width modulation) circuit, a very useful tool that, alas, can have negative side effects. For example, while it allows a fan to start reliably at unusually low speed, an improperly matched PWM control circuit can cause a DC fan to emit more clicking, buzzing and chattering noise as it is slowed. A similar effect may be happening with the monitor CFL bulbs. To modify this electronic circuit in order to reduce or eliminate the whining noise is an impossible challenge for most users.
Thankfully, there is a simple workaround within the software controls bundled with most video card drivers. The color adjustment screen in the display characteristics control panel also provides a brightness setting. Using this control reduces the brightness in the video card output. Moom 2 1 1 intelk download free. This bypasses the monitor’s electronic control circuit, which can be left at maximum brightness, thus eliminating the noise. It’s an approach that works even with years-old video cards such as a GeFore 4 MX onboard video.
The brightness setting in the color window of the Catalyst software for my ATI graphics card is set to -51, which makes the BenQ monitor perfectly bright for me while bypassing that monitor’s infernal whining brightness control. |
This workaround will obviously not work for LCD monitors that whine even at full brightness. A replacement with another sample or model is recommended in such cases. We have not tried replacing the CFL bulb of afflicted LCD monitors; it probably is not the cause, however. Arc rt 328t manual. Interestingly, the whine of CRT monitors can usually be reduced by setting its internal brightness control down. It’s also not clear whether any LED-lit monitors suffer the same problem.
CAUTION: If you are an image professional (or advanced amateur) who relies on color accuracy, this may not be a good solution. For details, please see the discussion in the forum linked below. If you find the color degradation with this approach to be serious, you may also want to try a combination of both monitor hardware brightness control and video driver software brightness reduction. With a decent monitor, for typical computer uage, you should be able to find a happy compromise between image integrity and aural peace.
Please help us help you! The SPCR staff and lab can only examine and report on a finite number of products. Reader contributions can expand our reach tremendously. Everyone viewing this page has a monitor. In the forum discussion linked above, please post the make and model of your monitor and whether it whines. If it does, describe the degree, nature and conditions. As this log grows, everyone can benefit by using it as a quick reference. When it gets big enough, we will turn it to a table with multiple models, samples and ratings, and keep it uptodate. It will become a highly useful resource for quiet monitor seekers.

We continue to explore the issue of high frequency tonal noise from many computer components. As we approach ever lower noise levels, this electronic whining often becomes critical; in “normal” (read: noisy) computers, it is masked by the noise of fans and hard drives. Power supplies, motherboards and video cards are the other main sources of electronic whine. The whine is often associated with power components, usually capacitors and coils. Poor circuit design is probably at fault; electronic resonances in circuits can cause the components to vibrate or ring, and the whining we hear is directly related to that ringing.
We hope that this is the first, not the last or only, article at SPCR to tackle the issue of electronic whining in computer components. If you have any solutions to offer, please share them with us, by email or in the discussion forums.

So if you have a computer and its making a High Pitch Hissing noise then welcome to the club as this may be an early sign that something will soon happen making your PC unusable. Even before that though the Computer Making High Pitch Hissing Noise is really annoying and can get to you. So in this article I will look at the issue and provide a solution that should help in fixing the problem.
What causing the Computer to make a High Pitch Hissing Noise?
Normally the high pitch noise can be caused by a power supply going bad or it could just have a build up of dust that’s messing with its normal operation.The causes are numerous and can also be related to the fan in the power supply. Its hard to tell exactly what the cause but its most definitely in most case a power supply issue.
Quick Test:
Power off the computer and while its plugged in but not powered on listen carefully at the power supply and see if you hear the sound. This would indicate its definitely the power supply issue.
Computer Making High Pitch Hissing Noise Fix:
Try all the following and one should fix your issue once and for all.
Computer Making High Pitched Noise Won't Start
1.Clean your Power supply of dust: If there is too much dust the power supply can die pre-maturly so get some canned Air or other duster and clean it out.
2. If that fails which is the more affordable solution then you will need to replace the power supply with a new one.Nothing good will come of a bad power supply and it best to get ahead of the problem and deal with it now.
Why Did my power Supply Go bad?
There are a number of reasons it became faulty which includes:
1.Its an old power supply.
2.Build up of dust over time.
3.Factory fault.
