You want few errors. How many errors you actually get depends on your
environment and your cable length.

Remember that cables don't carry digital signals. They carry analog signals
that your equipment interprets as digital values. The cable has to not
degrade the signal enough that *your* end equipment can still understand the
digital values. You can't hook the cable up to laboratory-quality test
equipment and say "Yep, no errors."
Which is not to say cheap cables aren't sufficient. It's merely to say that
cheap cables aren't necessarily sufficient just because it's digital.
It's the same reason you can only get ADSL service at certain distances from
the telco CO. It's an analog signal. It's only digital once it gets inside
your computer.

It wouldn't, unless you're actually getting bit errors.

Understand that there's a processor inside the TV that's interpolating
frames. It's not just painting the same frame twice. It's actually drawing
something different every frame, based on the motion vectors in the image.

so much "what color is your parachute?" as it is
"what color is your nose?"
