Howdy tonyrazza-ga,
A chart in the CNET.com article entitled "EDTV vs. HDTV native resolutions"
responds to your question quite nicely.

"... EDTV ...
If you feed it an HDTV signal, will you see a picture? Yes
Will it display every pixel of wide-screen DVD? Yes
Will it display every pixel of 720p HDTV? No
Will it display every pixel of 1080i HDTV? No
..."
For a more technical answer, here is the "A CONSUMER'S GUIDE TO THE WONDERFUL
WORLD OF HDTV" brochure from the Consumer Electronics Association (CEA).

"Like the highest quality HDTV, Enhanced Definition Television (EDTV) is an
all-in-one unit ? a display with a built-in decoder in either direct view or
rear projection design. In this case, you'll see at least a 480p image, rather
than 720p or 1080i. The screen can either be square-shaped (4:3 aspect ratio)
or widescreen (16:9). It receives, reproduces and outputs Dolby Digital sound.
An EDTV monitor has the same display parameters as an EDTV, but does not have
a built-in decoder. Occasionally, this type of TV is referred to as a
multimedia monitor.
The Enhanced Definition TV tuner receives all digital signals, but outputs
them to a TV at 480p resolution, rather than 720p or 1080i."
The CEA has several great publications, including the HDTV Guide.
http://www.ce.org/Press/CEA_Pubs/821.asp
"Jointly produced by TWICE Magazine and CEA, the HDTV Guide is the resource
for information on the analog-to-digital transition. The HDTV Guide includes
product charts, suggested retail prices, a list of retailers that carry HDTV
products and a list of the broadcasters sending HDTV signals."
If you need any clarification, please feel free to ask.
