I installed a new graphics card, a ATI Radeon 7500, in my old 2001 G4 Mac.
It works well.
I used a Belkin ADC to DVI adaptor and a DVI to DVI cable to connect my 19" Viewsonic VA1912w monitor. It works well.
I have an iMic connected to a Yamaha sound system. The audio is fine.
I connected the remaining VGA port on the ATI Radeon 7500 garaphic's card to my Sony Bravia HDTV's VGA port. I have two functioning screen on the Mac.
However, when I connect the HDTV using the VGA cable I suddenly get a "buzz" interference noise on the sound system. Disconnect the VGA cable and the noise stops. Connect it, it comes back.
A grounding problem? Any thoughts? Anyone else experienced this?
