I own an Emerson LC391EM3 TV, likely manufactureed for USA, late 2012. Will I get a significantly better?
picture, if I pay Comcast cable service extra money for high definition? We are quite satisfied with the picture quality.TV is 1920 by 1080 pixels 60 hertz aspectratio 16.9
tuner ATSC/NTSC. Will our other 20 year old TVs quit working if we get high definition? The Emerson owner's manual does not seem to answer any of these questions. It does not even say the TV is HD capable, but I suppose it is.
It was purchased in Jacksonville, Florida, USA, Dec 2012
