Hey guys, just need some technical help here.
First, this is my setup-
BenQ G2220HD 22" widescreen monitor
Logitech EX 100 wireless mouse/keyboard combo
Logitech Z4 2.1 speakers
Acer Aspire 4741G laptop
And I also have my ps3 plugged into the monitor and speakers.
I have the ps3 plugged into the monitor via a DVI/HDMI converter, and to the speakers through the RCA cables to an RCA/3.5mm converter, directly to the input on the speakers.
Then the laptop is connected to the monitor via VGA, and to the speakers with a 3.5mm cable going from the laptops audio jack to the component jack on the speakers wired remote.
The setup itself works fine, the video and audio works for everything, has since I got my ps3, and worked just fine exactly the same when I had an xbox 360.
The problem is that when I have both the laptop and ps3 audio plugged, I get an annoying humm from the speakers. It goes away when I unplug the ps3 or laptop audio.
Another thing I noticed is that the loudness and frequency of the humm changes depending on whats happening on screen. Darker colours give a deeper humm, lighter colours give a higher humm. Dont ask me to explain beyond that, I know nothing about audio stuff :P
Just wanted to know, is there any way to get rid of this annoyance? Could things be too close together?
(Also, the actual volume- not the volume of the humm- drops when I have both plugged in, but I think thats because its having to share between both things.)
