everything Gary said.

I don't know if the ION1 does or doesn't support HQscaling, both my
ION machines are on smaller TV's, so they may not, but it may not make
a difference on those screens either.

I have noticed on my GT220 that it does make a difference and is
enough better than the scaling in my plasma to ensure I enable it.
