Hum through the speakers when the monitor is plugged in.

post #1 of 4
Thread Starter 
I've been having an issue with a hum through my speakers. I found the problem but I don't know how to fix it. When my monitor is plugged into the PC via either DVI or HDMI I get a hum through my speakers. If I unplug it the hum goes away. The hum is even there if the DVI cord and audio cord are the only things plugged in. This includes power, no power cord was installed but I still get the hum through my amp. I tried plugging the monitor into a different power strip and outlet but that did not resolve the issue.

If it's a 60 Hz hum you're hearing, the hum is probably coming from your PC's power supply. It could be as simple as a broken ground wire in the plug going into the PSU, or leaky A/C noise radiating into the 3.3/5V bus. What brand of PSU is it?

I thought it was the PSU at first and I just replaced it with the Cooler Master V700. There was no difference when changing from the old PSU.

I don't know if it's a 60hz hum. It almost sounds more like a high pitch screech sound.

Asus said they would RMA the monitor if needed.

I ordered a toslink to rca converter, going to give that a go as I'd hate to send back my monitor. Hopefully it will clear up the issue.
