768 X 1366 is a common physical format for a 16:9 aspect flat panel screen. On such a screen, there are 768 rows of 1366 individual physical pixels. This is called the native resolution of the screen.

But the 720p digital picture format has 720 rows of 1280 pixels. So some kind of processing must occur within the TV monitor that magically makes each pixel in the picture look bigger by a factor of about 1.067 so the picture can fill the physical screen. This is called scaling.

For 1080 digital picture modes, the picture pixels are scaled down so the picture fits onto the screen.

So both modes can be displayed.

Maybe someone here knows how scaling is done but I suspect it's mathematically complex.

All HDTV can "accept" 1080i. Some TVs cannot "accept" 720P. All consumer HDTVs have only one native display format and all incoming HD signals get converted to that format.

For consumer CRT-based HDTVs that native format is always 1080i. For pixel-based HDTVs, that native format can be 720P, 768P, 788P, 1024P or 1080P depending on the display specifications. The above specs indicate a native format of 768P.

Since you didn't supply the make/model number, I cannot confirm if the TV will "accept" 720P as an incoming signal. This is not usually an issue since all STBs can convert 720P to 1080i.

It's sometimes an issue for gamers since there are some 720P games...

I am also asking hdtvs that do 720p and 1080i would convert all my PS3 games ( after PS3 comes out etc.) from 720p to 1080i?

Also if so... I am looking just for a 720p tv hope my games dont get converted.

The tv I am thinking about getting if it dont upconvert 720p to 1080i on it is the new Sharp 32 inch tv comeing out in May.

But if it dose convert 720p to 1080i:( I want the new 26 inch Sharp that comeing out real soon if it dose 720p only.

If it's a CRT-based TV, the native resolution will be 1080i. If it's an LCD-based flat panel, then it's likely to be 768P. If you're a gamer, you should ensure that the TV "accepts" the 720P signal. Once you have the make/model number we can check for you.

Provided the TV does the conversion, the final product is quite good since conversion is done all the time. This 720P vs other formats is usually quite overblown, especially at a 32" size.

Well I just found out:)! The 2 sharps I am looking at at www.sharpusa.com I just found out tru 26 inch to 37 they all only display hdtv in 720p!

I am going to wait tho... the new 32 inch and 37 inch is comeing out sometime in May and I.ll end up with one of thos. I would go with the small 26 inch new one but... it so wide and top to bottom to small and just to wide lol.

But I know why and it a good thing but I wanna be able to see top to bottom as big and sides wide too.
