Couple of HD TV questions

Why do smaller TV's only come in 720 P instead of 1080I Next question is I was told because I was getting a 720 P TV that it would be pointless to hook a blue-ray player up to it That I should just get a regular DVD player

well i'm not really sure. a lot of this might be differenting opinions. I watched a blu ray on a 720p tv, and it sure as hell looked a lot better than a dvd would.

of course the ideal situation is 1080P with a blu ray..but sometimes that is not always possible.

I have both a 720p and a 1080p and cant tell much of a difference at with a blu ray.

Given that 720p is 1280x720 resolution for a total of 921,600 pixels and 1080p resolution is 1920x1080 resolution for a total of 2,073,600 pixels, I'm going to jump to the conclusion that you simply can't squeeze 2m pixels into smaller screen sizes... or at very least, at smaller sizes, you have diminishing returns on how small of a pixel the human eye can discern anyway.

As a picture gets smaller, the resolution is less and less important.

Suppose you are looking at a screen with a line down the middle. The "sharpness" of the edges line is the resolution. If the line were as sharp as possible, for 1080, then as you shrink down the picture size, the individual pixels that show the edge of the line will get smaller. If the picture gets much smaller you can't even see the individual pixels of the edge of the line and thus you can no longer resolve 1080 or even 720. They both will look sharp. You may not resolve (resolution) a few pixels but the picture will "look" sharp.

We put a 32 inch Sony in our bedroom. I wouldn't want to go any smaller than that.

I "think" that you need 1080P for BluRay to play as it was intended to be seen.

Smaller HDTVs only come in 720p because you wouldn't be able to tell the difference between that resolution and 1080p when watching from a normal viewing distance. Conventional wisedom says that 720p is good enough for HDTVs smaller than 40". Get a blu-ray player or at least an upscaling DVD-player. It's worth the money in the long run.

Someone correct me if I am wrong, but Blu ray sends its content to the TV in 1080p format/signal. Not that it would be pointless with 720p, just wouldnt be the showing the best picture. But it still should be better then a normal DVD though.

You're kinda right. It does send the signal in 1080p. The TV will down convert it to 720p. It's still going to show the best picture for that TV. Since it's not possible for you to see a difference between 720p and 1080p on a 20" screen, you're still getting the best image for that screen size. Normal DVD sends out a 480p image, so you're right that it's better than normal.

Right, thats what I meant. It will show the picture in 720p, (which is the best that particular display can show), and not 1080p (which is what the signal form Blu ray would be).

They say with TV's 32 inches and smaller you can't see the difference. You would have to go larger than 32 inches to make a difference. At 32 inches most sources say not to bother wit the higher resolution even though it is available.

I think the only time the higher resolution would matter would be if the display is being used as a monitor for a PC rather than a TV.
