I've read and heard that with a new HDTV, you should turn sharpness to zero
because anything else adversely affects the picture. I've tried it and it
seems like it looks great. ANy advice?

Get a setup disk like Avia and go through their instructions on setting
sharpness using their test pattern.

It depends on the HDTV set..... some 25%, some 50%......

Only the Ovation AVIA DVD will tell you for sure when you run

AVIA DVD thru the component port.... No question then !!

You can see the sharpness clarity point with your eyes!!

There is no "sharpness clarity point". One wants to set the so called
sharpness control as far up as possible without introducing ringing or some
other visible artifact that introduces exaggerated line edges, etc. If set
too high fine detail cannot be reproduced on the screen. On many sets this
is at the minimum position of the control.

The controls they DON'T want you to adjust are inside or in a service
menu. Run it where it looks good. If you see ringing and find it
objectionable, back it off.

On my Sony, the 50% setting is zero sharpness. Left of that actually
starts blurring the image.

sharpness / contrast / color on my set seems to be interrelated, and
they need to be "adjusted" - in a synergistic manner.

Really, when it looks good to me - I just nail it. But too much of
anyone of them is - too much.

I would suggest using Avia or DVE as a guide to get an idea of what the
sharpness control does, but it is not realistic to assume that all sources
and siganls on a given source need the same setting. Bottom line is turn
the sharpness up when you have a clean source until the pix looks best
without being grainy or over enhanced and turn it down on a lousy sorce
until the grain or digital effects are softened enough to be a pleasing
picture to watch.

It depends on the model but generally yes. The 'sharpness' is artificial
edge enhancement develped to counteract analog bluring from the days of
analog signals. Most sets are designed to sell off the store floor. The
manufacturers expect the sets to be under florescent lights with a badly
oversplit analog signal. The default settings are designed to look best
under those conditions which, of course is not what is optimal for most
people's houses. Digital broadcast and souces connected with DVI/HDMI
generally don't benefit from such enhancement at all. In fact, the feature
can cause bad ringing and/or posterization (although that's ususally
excessive contrast) on channels or sources that are already edge enhanced at
the source, which includes most DVDs and many TV stations. Ultimately
though, you should go with what looks best to you for any given source and
don't be afraid to use different settings for different sources.

There are a couple of TV calibration DVDs but generally stock settings have
too much "sharpness" too much "colour" and too much "contrast" for a
realistic picture in a typical home setting.
