Do you understand digital vs. analog? If yes, then in fact you do agree with the message of the article: a non-defective cable transmits a digital signal just as correctly as any other non-defective cable. Your experience just indicates that slightly more expensive cables are less likely to be defective.
I wish HDMI equipment would display a counter of digital errors. For all non-defective cables, this counter should be 0 all the time.

Does the HDMI signal provide a checksum of any kind? I was under the impression that it's just a raw TMDS bitstream of color values with no redundancy.
- mrb 15y agoI read the specs myself and found out that: * control packets (non-video, non-audio) are protected using TMDS Error Reduction Coding (TERC4) * audio packets seem error-protected at a higher level (by Dolby or DTS?) * video packets are *not* error-protected Wow. I am shocked. How can anyone design a high-speed video digital transport layer these days without error correction?

- hiroprot 15y agoGood call on the display of errors...why is that not available in today's TVs? Or is it? Maybe in some special diagnostic mode?
