Yes, quite amazingly though the new DLP and LCD-projector HDTVs have a
native resolution in the range of 1280x720, many of them don't actually
take a 720p input.  Of if they do they "upscale" it to 1080i to display it!

Of course this is sort of a strange use of upscale.  It is more pixels but
at half the refresh rate it's definitely not an upscale if you are
watching sports.

Bizarre.  Would think instead they would want to be native at 720p and
translated 1080i to 720p.
