Do expensive HDMI cables result in a better picture or sound?

Surely an A/D or D/A converter relies on its own clock, not the implicit clock of the incoming signal?

Apparently not. Clock recovery uses a PLL.

This isn't necessarily relevant to the case where you've a digital display on the downstream side - indeed, I'd guess it's not - but they haven't covered that case even as far as saying that it's not.
