Sorry, but that makes no sense, Craig.
If I am watching a 1024 X 768 dislay right up close, I should be able to
see *any* artifact that any other 1024 X 768 display can resolve.
More precisely, if I'm standing 2' from a 26" screen, as I was last
night, that is equivalent to someone sitting 3.2' from a 42" 1024 X 768
screen. And plasmas of that size and resolution have been and are
commonplace. LCDs too, more recently, although they tend to be 1366 X
768 now.
I would agree with you only if I had been using S-video or composite
video interfaces between STB and display. *That* would have made many of
the artifacts undetectable. But I am using component interfaces. So the
bandwidth is there.

I'm simply saying that competition is what will prevent image quality
from degrading too much. It is, for example, why DBS is adding so much
HD capacity to their systems.
