Resolution v Hi Def

[MrSpanky]

I'm trying to grasp the relationship between resolution and hi definition classifications.  I just watched a 1080p clip on my monitor which is set to 1280x720.  Does that mean the clip was only viewed as high as 720?  Or do they not have any bearing on each other?

If you're monitor is displaying 720 vertical lines then that's what you saw.  Typically you see 3 sets of number for high-definition broadcast.  720p, 1080i, and 1080p.   This is relation to the number of rows of information displayed on the screen and the method in which they are drawn.  P means progressive in which each line is drawn in turn.  I means interlaced which means the even number lines are drawn then the odd, rinse repeat.  

My guess is that your monitor converted the signal to display it @ whatever resolution you have it set to.

Soulyss gave you the short answer.  Here is the long one-
