I have an Nvidea EVGA 01G-P3-1158-TR, a GTS 250.

I've connected my card to a Panasonic flat screen using a DVI to HDMI cable. The card recognizes the TV and lists it as a display. I set the Nvidea Control Panel to 720p, and set the displays as CLONE. I have to use clone since the TV and computer are in different rooms and moving either one is not an option.

My problem is that I'm not getting a picture on the TV. I've tried all three of the HDMI inputs on the TV with no luck, and have hunted down the TV manual to make sure there is no setting I have to change other than the input. I didn't find anything so hope someone here might have an idea.

I'd appreciate any help or advice I can get, thanks.

Thanks for your reply. When I set the graphics card to 720p for the TV it also changed the monitor to 720.

Here's the response I got from Panasonic:

"Thank you for your inquiry. As long as you have put the television on the proper input then the answer to your question is no. There is no setting on the TV that you could have overlooked as long as the TV has been set to the proper input. The TV is simply being used as a monitor. You now need to go into the monitor out settings of the computer and command the computer to output the signal. However, the manual does state that "use with a PC is not assumed" when using HDMI. This means that HDMI does not always work when connecting a PC to the television with HDMI. The TV may be set to the proper input and the computer has properly been told to output a signal but the TV is not guaranteed to work with the computer. Thank you for contacting Panasonic."

So now I wonder if it will work with S-Video, or a DVI to component cable, or an S video to component?

The TV is a Panasonic TH-42PX80U. If anyone is streaming video to that TV, please let me know.

Just thought about what I said above. DVI to component cable wouldn't work since the DVI signal is digital, while the component cable connection is analog. I wonder why they sell these? I guess when I have the time I'll move the computer to the other room and try S video.

I also did a good (long) Google search on the model of TV I have, and found three posts where others had no display using DVI to HDMI.

My first thought would be a cable issue. How long is the cable you are using? It will need to be a quality cable if it's over 10ft. The cable is at least partiallly working, as the TV is detected. But that doesn't mean the cable is sufficient.

Aside from that, you simply connect the TV (just like you would any other monitor). No special settings are needed on the TV.

I would suggest moving the TV or computer, and testing with a standard length cable.

S-Video is an option, but only as a last resort. Resolution would only be 640x480, maybe 800x600 if you are lucky.
