My screen is making a high pitched noise on a certain site

[Qrko]

So I have Asus VG248QE 144hz monitor that I use for everything also gaming I was doing some schoolwork and noticed a high pitched noise coming from the top of the monitor when I was using a Google Sheet. But when I switched to another web site the noise stopped instantly. There isn't anything else that I noticed during the noise. So should I be worried or just not even try to do something to this ?

BTW I'm using my screen always on 144Hz and my brightness is around 50-60 so it ain't even maxed out.

Might be caused by brightly colored pages. My old monitor has an issue where darker pages make it quieter, but brighter ones make it louder.

Different colors/intensity are made in monitors with different electrical frequencies. Certain frequencies are made with different amount of amps. The capacitors in your monitor may have a am audible charge up of high pitched sound when being charged with "x" amperage... I think this is why you are hearing this noise... Hopefully this helps, I'm also open to criticism with my limited physics/electronics knowledge lol..

But the site ain't that brightly colored and I have visited In my opinion more brightly colored site and now noise.

But I just don't get it why it makes the noise only on that site, because its almost only gray on the site and when I game and visit other sites. Nothing... just nothing. That is something that I just don't get.

So its not the brightness that really matters too much. Im saying at a very exact point in screen intensity this may happen... could be just a small glitch in the engineering. I would check to see if others with monitor experience the same noise and maybe even contact the manufacturer to see if they know anything about it.

Oh right. I'm gonna try and contact the support and if I get an answer from there I will tell what they say.

Sounds good.  Some capacitors will resonant at certain frequencies and i think this may be where your issue lies.. Maybe a capacitor is faulty, so check your warranty.

They said that return the factory settings which didn't work and also try the monitor in another pc what I can't do at least for now.
