question about HD

[KeypoX]

Ok so i know HD is just resolutions such as 720 is xxxx x 720 or what ever the first number is.

So computer monitors do quite a bit more than HDTV's. So my question is are we watching stuff in HD when we use the computer at 1280 x 1024 which is almost as high as 1080 HDTV resolution and i image many people use greater resolutions then that.

So when i put a regular dvd in and play it is it upscaled HD? Kinda like you can do with a DVD player that upscales to 1080i to your DVD player? So what is the difference from a computer monitor and a HDTV? Is it our video cards that cannot produce the HD quality videos?

The simple answer is 1920x1080 is a standard resolution. If it's 1920x1200 it's not HD resolution even though it is actually higher. So the image may look a bit odd depending on the card used and software used to decode the video.

I've noticed that DVDs look better on my TV than my monitor because the aspect ratio is not right. 1280x1024 is different than 1280x720

The aspect radio will be the same if the 16:9 source image is letterboxed.

If you run 1920x1080 on a 1920x1200 display letterboxed, you'll get perfect 1:1 pixel mapping, and hence the aspect ratio will not be altered in any way.
