A couple of years ago I had reason to evaluate the signal transmission
properties of DVI cables. I built some hardware which could detect and
record single bit errors in a DVI signal and ordered various cables from
cheap to expensive. The somewhat surprising finding was that many of
the expensive, fancy looking cables were awful at passing the signal and
produced lots of errors at the decoder. A lot of the cheap cables were
pretty bad too. The hands down winner with perfect signal transmission
was a decidedly ordinary beige cable from the low end of the price range.
Maybe the average computer user just doesn't notice the odd low level
sparkle? Certainly the average TV viewer won't.
