Ferrite cores and sharpness?
 

I just replaced the component cables between my DVD player and my TV
with an HDMI cable. I anticipated an increase in sharpness, but
actually the sharpness declined! The new cable has a ferrite core at
each end. Could this be the problem?

the HDMI cable is only carrying a big stream of 1s and 0s - binary code.
a ferrite core does not have the ability to reprogram computer code.

the only way something could affect the picture is if it stops the signal
getting through - enough that the error correction can't work.
if that happens, you won't get a less sharp picture - you'll get nasty
breakup.

more likely is that your tv has independent settings for each input - so
make sure the sharpness is set the same as it is on the component input.

You are assuming the software worked the first time. It is always
dangerous to trust software. But you know that.

He probably did not like them and thought he would keep going until he got
one he liked.

I'm sorry that you boys hurt your fingers scrolling down through a
duplicate message, so I'll explain. I use Mozilla Firefox to read
newsgroups and when a post is sussessful it helpfully gives me a "your
post was successful" message. Except for the first message, when it
did not appear. So I sighed softly and wrote the message again. The
second time I got the "successful" message. However, both messages
were posted to the newsgroup, prompting some folks who had not had an
opportunity to complain about anything all day to rip me with
merciless sarcasm and the sharpness of their acidic wit. I hope your
fingers are better soon.

If the cable is shielded, they can do that. If it is not shielded the best
they can do is round off the sharp edges of the signal, which is probably
not what you want to do for HDMI (round them too much and you can lose the
whole signal). They can also reduce common mode induced lightning surges.
