What is 1080p? How do I find out what my tv is? I think I will just be paying DirecTV for the rest of my life
If your new HDTV is larger than 32", chances are it's 1080p (check your user's manual for details).
Most 32" and smaller HDTVs are (at most) 720p.
If you have an older, "tube" TV, it obvously isn't 1080p (it's 480i).
