Electrical sound from the monitor?

[ItzUknown]

Recenlty, my 24inch ultragear monitor has been making a sound similar like that of an electrical interfence. At first I noticed that the frequency of it changed depending on whatever was on screen. Now (after a few minutes of it making the sound) it has stopped change the sound and is staying on one frequency. I don't really mind it, but I don't think its normal for it to make this sound. Also, I disabled the onboard speakers, thinking that they may interfere with my other speakers.

Coil whine or electrical noise; means it's nicely old.

contact the supplier and get it replaced if purchased in October....then the issue resolves itself as this is not normal to have strange whines sounds whatever coming form the monitor. even the speaker interference is not like the old days of my first stereo in the 70's when the speakers would pick up police car chatter.

That's a new monitor and it shouldn't be doing that if provided clean power!

Does it do the same on a different socket and without the PC attached?

Well I don't have a second wall plug, so everything is connected together on a power strip. I could try different socket on there though!

An older monitor of mine also did that for some time and then stopped. It has been working for almost 10 years with no problem.

Might be a busted cap inside. Coil whine in a flat monitor is rare as it handles low amounts of current.

Its not loud anymore though. Like, I need to get my ear up to the screen and even then you can't really hear it. Only reason I noticed yesterday was because it was like 2am and ther was no sound coming from outside.

Update!! I tried to disconnect my speakers (not the built in ones, my logitech z120) because I noticed that the whine was louder when I turned up the volume and the noise went away! Plugged them back in and sure enough the sound is back. I don't really know why this is happening but I think this rules out the monitor being a problem.

Get better speakers.
