I have a 19" AOC e2043f. I have been struggling with a buzzing noise that I thought was coming from my speakers or from the computer. It probably started around the time my old monitor power supply failed and I got a new one, but I'm not sure. Now I know the monitor is causing the speakers to buzz when its on (they are Logitech 5.1 speakers). Any fixes? The monitor shuts itsself off occasionally throughout the day and turns back on, taking about 3-5 secs for the whole process. It didn't do this before I got the new power supply.
