I recently found an old HDTV out put dongle in my cupboard-o'-crap and wanted to experiment with my old CRT tv. I have managed to get my PC to detect the tv (says its HDTV though. But this wont affect it) and it is sending a signal out to it but the tv wont pick it up. It scrolls through the channels and picks up nothing. Does anyone have any suggestions. I am plugging it in through an S-video out put on my GPU and using composite into SCART into the TV. I know its an anchient tv but its worth a try.
