What would I need in order to watch streaming video on a tv screen without blurriness? - watch streaming playmate with the apes

I subscribed to a website video streaming and many things that I see.

What equipment should I buy to make sure that these things on a TV monitor can be viewed?

I think I need some kind of cable between my computer to the TV. An HDTV? And perhaps a special video card?

Who done this successfully?
