Problem with my new samsung plasma tv 51 inch series 450?

It's this one: http://m.samsung.com/us/video/tvs/PN51E450A1FXZA#gallery

It has pretty good ratings, so I purchased it and I have time warner cable with hd channels. I change settings and it still looks kinda blurry and nothing like how it was in the stores. My cable box has an hdmi cable so I don't understand. I've researched online and done everything they tell from changing the contrast and sharpness and all of that but I still can't get it to look at least crisp and clear. Help!!!

Not all programming is HD. Have you talked to Time Warner? If you're watching an actual HD channel, and using the HDMI cable, call Samsung.

Samsung is an excellent TV... With many cable boxes, HD is on a different channel than regular STD channels you are used to.. For instance, here in Los Angeles, Time Warner NBC is on channel 4.. To get channel 4 in HD, I have to go to channel 404 <-----!! Check with Time Warner, and see if you have HD service, and hope you are familiar with where the HD channels are..
