I just bought a graphics card that has an HDMI port. I'm trying to connect via HDMI w/Ethernet to TV, but for some reason it isn't working. I've previously used the same cable from a VGA+sound to HDMI converter (and that worked). The PC recognizes a second monitor, but the TV displays "recording data" before later displaying "no input" I have a visio tv a couple years old. Any ideas?
