Slight high-frequency beeping on a white background, e.g. Excel, Firefox?
Hello everyone,
Recently, I've been noticing a faint, high-pitched beeping noise coming from my PC whenever I have a white page open in Firefox or Excel. The darker the page becomes, the less beeping I hear, or the less noise I hear at all.
I had this problem years ago, but unfortunately I don't remember how I solved it… I haven't installed any new hardware in the last few weeks, except for GPU drivers and such. But I think it's a hardware issue.
Does anyone know the problem and how to solve it?
As I perceive it, I would say 90% of it comes from the PC because it is right next to me
PS: Funnily enough, I have exactly the same beeping (only louder) from a UV lamp mosquito killer 😀 but it's definitely off, that's not what's causing it.

Use the HDMI cable or USB cable (for audio signals, sound, loudspeakers) differently. Because (bad shielded) cheap HDMI cables or USB cables can interfere with each other.
Simply separate these cables from each other locally, or unused cables (other USB ports, other better cables use), could ease or even eliminate the problem.
Good luck!
Hey, Transisator, thanks for the help. However, I generally buy only high-quality cables. I didn’t change anything at the slots or at the cables last week.
If someone could tell me exactly why it is in a white background (such as, for example, with a good question) piept’s and nowhere else, then it might be possible to limit the problem also strongly.
White color means all colors RGB (red, green, blue) are on the display to the maximum and thus give the color white. Signal technology is the extreme/highest RGB signal/bit values ​​( 255, 255, 255 ), ie presumably homogeneous signal profiles on the data lines INSIDE, OUTSIDE of the display, PC, graphics card, cable ….
Also high-quality cables are just as good as the actual technical data are. An expensive price is not an argument for interference-free connections. Physical disorders cannot be overwritten with money or good product advertising. The deciding factor is the actual technology, materials and methods used to curb disturbances.
A switching power supply (in the display, PC, …) can also give high-frequency sound (swinging of sheet metal and copper cable), especially if it is not loaded (so little current draws).
Here is an Android app to learn more about the frequency and origin of the sound source. It will be about 12 to 17 kHz.

If cables take off unnecessary power supplies, the "white image" is no longer a pip.
Good luck!
