Why Sell 1080P TV's Smaller Then 46"??

[slaizer2000]

native resolution support always provides the best quality. As in no conversion or downsampling. If you put a 1080p signal into a 1080p device there is no conversion and you get 1080p. If you dump a 1080p signal into a 720p device there is some type of conversion going on in order for the TV to display the video in its native format.

At less than 46" Tv will you be able to see the difference or not I am not sure. But whenever you do any type of conversion with audio or images/video you always loose some data/quality. If done right this loss is not noticeable to the naked eye but there still usually is some type of loss. Same reason why you would want to stick with an all digital path and not use analog cables as you convert and loose quality.

also similar reasoning why you want a TV that can handle a 24hz source because the blu-rays are in this format and if you Tv can handle this format or evenly handle it (times 5 and not 3/2 pulldown) then the quality if better.

There may also be some cost savings during manufacturing. why produce eletronics to support 720p and 1080p when you can jsut product 1080p products. Fewer componants equals fewer different parts and manufacturing lines for the company.
