I came across multiple computer displays (computer monitors) that had strange noise emanating from the back of it.
The noise is high pitched and often people might not hear it at all. It resembles a high pitch buzz, high pitch humming or high pitch sizzling.
The problem, I believe, is because of the monitor power supply which is faulty somehow or became faulty over time and this is the culprit.
Often it is fixed by raising the Brightness setting to 100%. However, one of my displays (I have three) is showing the same symptoms even when he is on stand by.
Any idea on how to fix or what to do with this would be appreciated.
