Contains no information. Some MAY work for this but MAY not work for that. Explain specifically what physical properties in a cable produces higher bandwidth and why these properties are more costly to provide in a cable.
[/quote]Transmission problems are not unusual especially with longer cables as they are typically used for projectors, and the symptoms are often exactly what the OP described. And badly attached connectors can produce unwanted HF reflections in the cable which can produce transmission errors too.[/quote]
Contains no information. Already acknowledged that long, skinny cables with no shielding can cause issues as can loose connectors. Again, not costly to avoid.
[/quote]We are not talking about S/PDIF here. HDMI uses bandwidths of several Gb/s. I can assure you that your coat hanger won't work.
There is actually a rather strict set of technical requirements for the certification of HDMI cables including eye diagram limits etc.[/quote]
Your personal assurance means so much.
Again, explain what physical cable properties at what levels produces the proper bandwidth for 3D or 1080p60, and why it costs more to deliver this level of bandwidth. Explain the bandwidth of a coat hanger and how it is too limited for 3D or 1080p60. Explain eye diagram limits and why it is more expensive for a cable to work
It is you that has missed the point that a cheap, non-exotic cable can do the job just fine for HDMI. Seems the OP is doing fine now with a cheap, old cable for HDMI and its strict set of technical requirements.
