The definitions '720p' and '1080i/p' are all based on resolutions. Yes, if connected by DVI and at the correct resolution
, it will be HD.
Let's give you a little crashcourse on what the resoutions of HD are.
720p = 720 vertical lines
. A resolution is read out widthx
height. And, ofcourse, Vertical Lines are defined as height. For example a widescreen resolution with a HD 720p is height
is the most usualy 720p HD resolution if I remember rightly. 1080i/p is exactly the same, usually at the resolution of 1920x1080
= Interlaced, and p
= Progressive. They are both types of scan mode and give different picture qualities, as p is 30 frames per second whereas i is 25 frames per second.
In other words, you need a resolution with 720 or 1080 vertical lines for HD video to display properly.
