your monitor might meet minimum hd specs, 720, and even be able to display 1080 material....but depending on the disc...it might require hdcp connection.
to also better enable you to understand...you can search for HD trailers in various formats, whether they be wmv or mov...etc...you could play those and they could come in either 720 or 1080...trailers usually require no hardware copy protection transfer protocols...dl and play to see that your monitor can actually display them...
you could buy a set top box to hook up to your pc monitor, depending on the box's connections. "HD" (1080) material in the sense of the HD discs (HDdvd or BD) could be limited only through hdcp connections. 720 material usually does not carry the same restrictions and can be passed via component connections.
it is all about regulation....read up...fun stuff
