I have been running this set up for at least a year and I have never had any issues. I use my HDTV as a second monitor which connects to my NVIDIA graphics card using MiniHDMI (card) / HDMI (tv) cable. One day I was going to watch a movie on the TV through my PC but I turned the TV on and it says "No Signal" on my TV. I tried unplugging it and replugging the cable on both ends multiple times and have restarted the PC multiple times. I plugged into all 3 different HDMI slots. I updated my graphics card. Now I'm out of ideas. The computer and graphics card detect my TV however, which is strange. So if NVIDIA and my PC detect the connection as if the TV were on then why the heck do I have no picture or sound?

 

Graphics Card

NVIDIA GeForce GTX 550 TI

Are you selecting the correct input channel on your TV ?  Our main TV has several different inputs - 2xHDMI, Scart, composite video, etc. - and if you don't select the one your signal source is connected to then you won't see the signal on the TV.
