Hi Joe
I think the answer to one of your questions...lies somewhere in your living room...
Have you compared the two connections on your display ?
Do it ! Have some friends over and compare...
Do YOU or ANYONE there notice a difference ?
I only have one DVI source(computer) for now...
and for switching purposes(my computer kept shutting off my secondary display when not in use)..I have bypassed my 1070...and ran my DVI straight to my projector...
Movies look awesome through my 480p dvd player(component)...
but...
from the computer(movies at720p)...OUCH !!!
(or off-air HDTV at 1080i) AYOYE!!!
that picture is crisp and clean....
I'M pretty sure your panasonic display will give you that answer...
Now...take that plunge...order those beasts...
and get ready for bliss...
