If you have Time Warner Cable and you have upgraded your television set to a high-definition model, then you will need to contact Time Warner to see what HD choices they have for you.
Time Warner does offer HD cable television for its HD television customers, but like most other cable providers, it isn't offered everywhere. With Time Warner HD cable, you can still get all of your favorite channels to watch, but you can watch it in a more theater-like setting.
Time Warner only requires you to upgrade to a new digital HD-enhanced cable box and they will install it for you. If you are already a Time Warner customer, all of this will be done free of charge.
It is important to remember that even if you have a HD television and HD cable, not every station will offer HD programming. Check with Time Warner to see what channels are available and how much HD cable will cost you!
