I have recently tried hooking up my PC via DVI to my plasma. It doesn't seem to recognized any connection...keeps indicating: No Signal.

I have also tried using VGA connection as well. My video card(s) came with both.

I have tried a single card configuration and an SLI configuration and in both VGA and AVI and still...get nothing.

Have these ports been "deactivated" in some way? Is there some sort of code that needs to be entered to turn this feature on within my TV? I don't think the ports are damaged...they have never been used. Also...what is the likelihood that BOTH connectors are FUBAR?

Anyhow...I am a bit frazzled.
