Many projectors will take a HDTV signal and down convert it to there native resolution. This is not HDTV. To show HDTV a projector must at least have minimum native resolution of 1280x720 and have hi-band component inputs.
Isn't 1280x720 just one portion of the HDTV specification? If I understand it correctly, HDTV allows for a multitude of resolutions in either interlaced or progressive modes.
I think it's reasonable to call a device compliant if it can process and display an HDTV signal. Higher resolutions will, of course, allow for a better display of higher resolution HDTV signals. 1080p anyone?
the way I understand it is that if the display can process the 720P or 1080i signal to it's native or compressed resolution, then it's HD ready. Most digital TV's, RP DLP's and plasma's don't have the resolution to display the full 1920 X 1080 resoultion but can still display a picture are considered HDTV's by most electronic companies.
