Does HD improve LCD TV sound quality?

Usually it does. If you invest in a HDTV, you will be receiving your broadcasts in Dolby Digital 5.1 surround sound - a great leap up from traditional sound broadcast technology.

Here’s a tip: If you want to get the very best enjoyment out of high definition sound, you should invest in a good set of surround sound speakers to hook up to your TV.

This can improve the enjoyment of watching a movie or television show immensely - it will be like getting proper cinema sound - minus the annoying popcorn crunching of the guy next to you!
