So, I just read this:
[Link: cepro.com]. It's named
Boccaccio: A Better Way to Power Active HDMI Cables
and subtitled
Jeff Boccaccio on the age-old question: "Is there an actual HDMI failure or is it related to a power supply issue?"
Jeff Boccaccio defines and explains active HDMI cables in a February 2014 article in CEPro. Let's say these cables had already been on the market for three years. Now, 7 1/2 years later, this is an age-old question?
There's this:
As the failing samples arrive into DPL Labs they are categorized according to if a device is internally powered, requiring external power or supplying its own external power source.
But where's the link to this list, so that DPL can help us? Could you please share something about "
A Better Way to Power Active HDMI Cables"?But how are these power supplies rated? If it claims 500ma does that mean it can provide 500ma and hold its regulated 5-volt output?
Yes, exactly, if its rating is accurate. NO HDMI product should come with a power supply that does not meet its spec.
We’ve had power supplies come in that when pushed to their max current the output voltage fell to less than 4.2 volts DC.
YES, if it claims 5 volts, regulated, at 500 mA, then if it falls to 4.2 volts when 500 mA is drawn, then THE POWER SUPPLY IS CRAP AND THIS SHOULD BE PUBLICIZED. Where's the list of products that DPL must have seen in order to ask this question?
After further development, we have
And the question then looms, is there an actual HDMI failure or is it related to a power supply issue?
What? An article named "A Better Way to Power Active HDMI Cables" ends up with a totally basic question about the nature of the problem? Where is this "Better Way to Power Active HDMI Cables?"
