Question

What is the difference between "HD Ready" and "Full HD" in relation to TV's?

Answer 1

HD Ready means it is an HD monitor and can display HD signals, but needs an external TV Tuner.

Full HD usually means it is a 1080p HDTV

Answer 2

High Definition TVs that are HD-Ready do not have built-in HD tuners inside them. That means you need an "outboard" HD tuner in order to tune in and watch your favorite shows in Hi Definition.  

This outboard box could be from a Satellite TV system (like DirecTV), or a High Definition box from your Cable company, or a stand-alone High Definition tuner connected to an outside TV antenna for over-the-air broadcasts.

HD-Integrated means that the set has a High Definition tuner built in.  These TVs can receive over-the-air HD broadcasts when connected to an outside TV antenna.  If the set is labeled "DCR" or Digital Cable Ready, you can rent a CableCard from your local Cable Company to receive HD shows.  This CableCard goes into a special slot on the TV and eliminates the need for an outboard cable box, a nice convenience.  You may give up getting Pay-Per-View/Video on Demand and an on-screen Cable channel guide when you use a Cable Card because you may need the cable box to get those features.
