Question about Panasonic Viera TH-42PZ80U Plasma TV
Installed graphics card driver connected laptop to hdmi in on back of tv. computer says im connected for DUPLICATE, but tv shows hdmi not connected.
HDMI is goofy. Connect everything while it is off and then power everything up. That should take care of it after the first time you do it.

if I understand your question properly.. its because your direct tv output doesnt broadcast in high def so its giving you the standard tv definition inputs which are RGB or Component.so you will lose picture quality cos its running at fewer lines or pixels. hope this helps

On the MacBook, check the Displays pane in System Preferences to make sure the settings for the external monitor are correct. It's possible that the system is not recognizing the adapter or it has the wrong resolution setting, so it's not sending out any signal that the adapter can use.
Many of the better DVD players and high-end video game consoles use HDMI. You can use one of those as a test signal generator to check the TV.
You may get better results if you use a DVI-HDMI converter, although you would need to get the DisplayPort to DVI cable. This will avoid converting to analog VGA signals and back to digital again.
