I have 3 TV at home but I think these 3 TV's is very old. All of them is 21" inch screen and NOT even Plasma TV. But now come a new one called "HDTV" . Here is some information about it.

HDTV The NEW Must See TV

A substantial amount of the words here are all inter-connected to and about genealogy. Understand them to get an overall understanding on genealogy.

There are two different digital formats for TVs. One is SDTV, which means Standard Definition TV, and HDTV, which is the newest in TV technology.

This must see new TV gives the SDTV a new look. The picture is so much clearer, sharper, and almost three-dimensional.

HDTV has lifelike pictures and theater sound. It has a high resolution, which gives astonishing clarity. Its sharper, wider and more like a theater screen than a TV set. It is as clear as a computer monitor as it uses the same technology. Since most of us are use to the sharpness and clarity of our computer monitor, it means that we want the same technology when we watch our TV.

This computer sharpness has to do with the amount of pixels used on a computer monitor. The lowest resolution is 640 x 768 pixels. Some monitors go as high as 1024 x 768.
