43" Plasma does not recognize PC input.

I recently bought a 43" Plasma (PN43D450A2DX7A) and noticed that it has a HDMI/DVI input which I assume is specifically designed to connect a PC. I have followed the guidelines in the users manual and cannot get the TV to recognize that the PC is connected, however my PC is recognizing that I have a Samsung screen connected to it. Here are my specs.

Be sure to try other PCs

While this has been discusses before about video settings, the number of times I find other PCs work is growing.

Still not recognizing input.

Thanks for your quick response and for giving me some troubleshooting advice other than "try a different pc." However, I have tried all of the input names and I still cannot get the TV to recognize the input. I'm running a 25ft DVI to HDMI cable, I don't know if that would make a difference and I have the resolution set to 1024x768 which is the max supported resolution for this screen. Got any other advice?

Has this cable worked with anything else?

And 25 feet is a clue. Try shorter first.
