No signal with hdmi
I just purchased a new samsung lcd hdtv. I am trying to connect it to my direct tv hd reciever. The tv works fine when using the component cables for sound and audio, although pic. is not that great. I was told that I need to switch over to an hdmi cable to get the hd picture. I am told you just plug one end of the hdmi cable into the hdmi slot on the reciever and the other end into the hdmi slot on the tv. (My tv has 4 hdmi slots.)When I do this my tv does not get a signal from my satellite reciever but does recognize that the hdmi cable is being used.. Any help?
