I have connected my PC (15-pin) the my TV (15-pin) and the TV projects the PC just fine. As a matter of fact its great. However, I get a message in the middle of the TV that says "check signal cable" blocking my view. I looked it up and the answer says either I accidentaly set the input to PC ( did it on purpose ) or the cable is a bad cable (this is the third one and the picture is perfect).
So I have no problem with the PC to the TV but rather the message that sits in the middle of the screen blocking my view of a great PC picture.
What kind of cable are you using to connect your PC to your television? I usually use a DVI-to-DVI cable for my television. Usually when that comes up, it's because something isn't connected properly.
