Can you use a HDmi cable on a HD ready tv?

You look at the back of a HDTV or HD ready TV to determine what input plugs exist. You can also use the owners manual. Normally an HD ready TV is an older model that does not have an HD turner for the HD Television broadcasts and does mot has HDMI inputs and instead has the 5 RCA Plug component connection for 720P HD input or an S-Video connection input or even both. They sell 5 RCA style plug Component to HDMI connection cable for use with the PS3 and that cable can be used for any HDMI to component connection.
