Here is All the info you need to know about HDTV's and weather you should buy that 65inch sharp aqous with 1080p and 240hz
First should you get HD TV.
yes, yes you should.
Standard Defintion TV only has a resolution of 600x480, a 720p television will have a Resolution of 1024x720-1680x1050, most common being 1366x768, a 1080p TV will have a resolution of 1920x1080 or higher, yes alot of your computer monitors are better then what TV's are doing.
your eyes will thank you for a clear picture, but a HD TV has its down sides too, if your watching a standard definition feed, its gonna look worse then an older TV, the Tuners that are in most HD TV's are Designed Specifically for HD, if you watch alot of Standard Def TV, grab a Panasonic, they give you a better TV tuner but cost a little bit more.
So 1080p is better right?
No its not, for several reasons as well first very few things actually broad cast in 1080p, a few video games your computer,the odd camcorder, and blu-ray(BTW Blu-ray is absolutly useless with Hard Drives being as cheap as they are). so if your source is only 720p. Most video games, DVD's, HD Cable/satilite, most Camcorders you wont see a 1080p picture even if you have a 1080p TV, you dont need 1080p unless you have over a 50inch television and even then, are your eyes good enough to see the minor increase in quility? or would sitting an extra foot away from the TV help you? since moving futher away from the screen has the same effect as having a better resolution, alot of the 720p verse the 1080p will come down to your own personal eye sight as well as the hz on the TV 60/120/240hz does your eye see the differance? no? dont bother with it.
and as for price $600 for a 37inch LCD TV is pretty cheap.....
