I'm curious about the relation between aspect ratio and pixel count. I'm not sure if pixel counts are just pixel counts or if they really do have a native resolution. Basing on computers, am I correct in thinking 1600x1200 is a 4:3 pixel count, 1920x1080 is a 16:9 pixel count and 1920x1200 is a 16:10 pixel count? I know TVs can scale this up or down but how come TVs don't know how to take something like widescreen and stretch it to fill a whole 4:3 screen? On my 1920x1200 computer monitor for instance, I can use Divx to take 4:3 or 16:9 material and change it to a 16:10 so I can full screen it, I know there's something not right about that method but hey, the picture doesn't look weird to me. I'm kind of confused how it all works. If you have a 1920x1080 resolution, is it any aspect the filmmaker wants it to be, 16:9, 2.35:1 etc, or is it native to one aspect and TVs scale up/down to fit it. I've seen these videos online that are supposed to be 1920x1080p but according to their properties they are only 1920x816p because of 2.35:1 aspect ratio. Why would you call a 2.35:1 video 1920x1080 if it's not really 1920x1080?
