Dont notice much of difference between high quality and hd.

I just signed up for this site. I been following it for long time just never go into community stuff but i signed up so i could get hd video but seems not much better than free high quality.

On my flimsy little 27" monitor neither do I. 
I do on the huge TV though

Oh my bad i notice it better now.
 
I was watching wii qucik look but wii is not hd any way.
 
360 ones and ps3 and pc look better in hd.

When I'm just using the video player I sometimes don't notice. But I've been downloading and watching the DP endurance run on my big TV, and my brother has mistaken the video for me playing the game more than once.
