Re: Color Variation

Yeah, the problem is your new TV is TOO good....these variations have always
been there, but the old sets weren't good enough to show them...kinda
smudged all that stuff. It's kinda the way you can now see every pore and
zit on an HD closeup.

Given that colors are supposed to be correct in digital, and that
circuits
like these can be fooled rather easily (unless based on some VITS signals
that were in NTSC), I suspect they are not doing it anymore. It is up to
the programming source to produce the colors correctly into digital.
Once
that is done, they don't change until it becomes analog again at your
end.
And your end surely would not make that change different by channel. It
is
possible the cable provider is screwing with it (if you are on cable).
Are
these variations consistent across all programming from the same channel?

Thanks for responding, Phil.

The variations I'm seeing are not just related to different channels.
Sometimes they occur on the same channel, even in the same picture. When
news programs, for example, go to a remote the color balance may be
different. The difference is more obvious when the studio shot and the
remote are shown simultaneously, as in a split screen presentation. The
variation does not appear on all channels all the time. Sometimes I get a
"perfect" picture. Sometimes something's off.

Not sure whether its Cablevision's fault or simply because of sloppy or
nonexistent color balancing at the source.

On my old RCA analog set, These same variations occur, but are
substantially reduced when I turn on Autocolor. That's why I was asking if
any digital HDTV's come with autocolor although it might be hiding under a
different name.

Thanks for any information you may have on this matter.
