monitor emits high pitched scream

Frybyte · 04-05-2005, 10:05 AM

I have been hearing a horrible high pitch from a new computer- I thought that perhaps it was the HD or something inside the case but I now know that the monitor is emitting the sound.
However I have no idea how to get into whatever part of the OS {either XP or Mepis} to solve the problem.
Direct me please.
Thanks
Jay

Usually happens to older monitors, but could happen to new as well, it's usually the frequency you're running the monitor at. Instead of running at 60Hz, maybe run it at 72Hz, or vice versa.

When power on the monitor, it is normal that there is a scream. But there is often scream when it is in OS, it is innormal. Maybe your monitor is degraded badly.

Does the monitor have built-in speakers?
If so, it could be that the speaker wires are picking up crosstalk from the video signa.
Re-routing the speaker wires or shielding them could then solve the problem.

Thank you all for input. It turned out to be the refresh frequency. I had to set it at 100 to get the sound to go away but it's gone now.

I hope the monitor survives for awhile as I don't have the budget to replace it just yet, but the fact that it did make all that noise probably means that I should start saving now.
