I have a 720p samsung high definition television and a 1080p LG home theatre system and it uses an HD-MI connection cable to connect the home theatre system to the tv. After i plugged in everything and connected the woofer and Additional speakers i connected the HD-MI cable to the television and the home theatre system. When i went to the TVs menu and selected the home theatre system from the "inputs" screen the connection could not be made. I checked the cords and cables and speakers and received the same result once more. I began to believe that maybe a 720p television can't support a 1080p sound system and i went to yahoo for answers. My other question is if it can be connected, how? and if it can't what can i do to make a sufficient home theatre?
