What are you talking about? The TV only displays the signal sent to
it. When I press the "info" button it shows the input resolution.
With dish and s video it shows 480 with component dvd it says 480.
With OTA its 720p or 1080i. The upconconvert dvd shows 1080 or 720.
This is a plasma hdtv. There is no "automatic" conversion on any hdtv
I've seen and used- Hitachi, Sony, Panasonic- they show what goes in
and that's it!

No, your TV displays the information what type of input signal it
receives, but your plasma display has a fixed number of physical
pixels.

It scales the incoming picture to fill those pixels. Exactly how it
does this scaling varies with the TV model (and scaling circuits) but
it is never a simple repeat of input pixels. So the scaling performed
by your DVD player is of the same principle the TV does, but since the
algorithms might be different the resulting quality also varies.
