Looking at new big screens replacing an 11 year old RCA 52". One we looked at was a Hitachi 65" 16:9 wide screen good picture quality in hdtv. But when the salseman switched to regular cable like we have the picture doesn't take up the entire screen. He said Hitachi had a feature to expand the picture to the width of the screen, when he did that the images on the sreen looked shorter and wider. Not a very good picture then. Are all 16:9 wide screens this way. Thanks for any input.
