720p is HD, just not true HD. in england we call it HD ready, so
this computer does not meet that requirement.
If you want full HD, look for PCs with a resolution of 1920 x 1080
however, alot of media played through say HD channels on a TV are 720p.
And as it has no bluray player you couldnt play high def stuff from a disc, you'd have to download bluray rips or stream HD material
