Hello everyone;

Sorry if this is a common question, I've been googling for about 45 minutes to no avail. Also, if this is the inappropriate website/forum, I appologize in advance! Anyhoo...

I have three PCs. If I hook any of them up via DVI or VGA to my LG 52" television (I could dig up a model, not sure exactly where receipt is, I purchased it some time ago) it omits a very loud buzzing as soon as power is put in to any of the PCs. The only thing hooked up is the PC, the DVI or VGA cable, and the power cable. Well, that's not entirely true, there is also an older Kenwood receiver that I have the television connected to, but I can disconnect that altogether (power wise, at least) and it still makes a buzzing sound over the television speakers. If I change it to HDMI1/DVI on my television, the buzzing will stop, however once I plug in audio at that point, the buzzing returns. I bought a ground loop isolator, and that at least gets rid of the audio buzz, but what can I do, if anything, to get rid of the buzz that occurs just when the PC is plugged in and it's on a mode other than HDMI1/DVI? Any advice is appreciated, thanks.

C.

Hi,

Are you using high quality shielded cale with ferrite cores (cylinders at each end)? see this site for an example;

Note I am not endorsing this particular site/cable just using as an example.

regards

I don't know.. I've tried multiple cables, (3 or 4) being in this price range, little reluctant to buy another one. I'll try and find out, thanks for the input, I still have this issue.
