Yes I'm on a macbook pro. But the problem is a ground loop caused by the external monitor. If I disconnect the monitor, or the dvi port, the hum disappear.
I have this ground loop because I have 2 power strip (4 socket each) chain connected..
I tried to connect the ext monitor to another socket in my room and the hum disappear.
I'm planning to buy a 8x power strip
Hmm I've battled this problem for a while and just gave up on using my external monitor. What's weird is that I hear no noise on my headphone jack of my duet only on the monitor outputs. I'm pretty sure I've tried different sockets too. The only thing that seemed to help was turning off my wireless, but I can still hear the noise, only much much less.
