Hold your horses... I was confused what I read yours.
I finally found this link for a HDTV introduction. A few weeks ago, a man explained to me about the HDTV, and I discovered that he was wrong. It is not my fault. Here is the link:
Television video HDTV
CRT's format is NTSC which contains 525 lines. (i.e. size 640 x 480 and 852 x 480). The other word is for a "square" format.
A wide format is called HDTV which contains 1080P and 730P. (i.e.1280 x 720 and 1920 x 1080). The other word is for a "rectangle" format.
For Laser TV, I assume that it would be the same size as HDTV format. I am not quite sure if it says that it will save 1/3 of electricity. I cannot go into the detail unless you know about it. (I am sure that there will be a new one which called Laser TV that will come out in 2007. My mother heard it on the radio.)
I personally don't like to read a very long article about TV stuff.
I cannot imagine that some people would buy a biggest HDTV like 60 inches. It probably makes the room flashy - just like a thunder and lighting storm that would scare them off. hee hee hee.
