HDTV is a new format for displaying a TV picture. It has higher resolution and clarity than the old NTSC format. Most stations that are broadcasting digital signals are now using 4 channels for every 1 they had before. They are reserving some channels for HDTV format and some channels for NTSC format. An HDTV will display the HDTV format and probably the NTSC format as well. An HDTV monitor can display the same picture, but probably lacks a tuner to actually receive the television signals. You need to plug something into it like a computer, a DVD player, or a tuner. If that thing sends out an HDTV signal then you can see it on the monitor.
