HDMI Cable question

What is the difference between a 28AWG High Speed cable with ferret cores and a 24 AWG CL2 with net jacket?

Thanks in advance.

The outer braided nylon jacket (net jacket) provides strong protection and increased cut resistance to the inner cable.

If the cable is going to run in, thru or behind a wall, the best thing is to make sure it is CL2 (designed with better shielding for in wall installation).

I quite often see people talking about the thin wire vs thick wire issue but in my opinion if you buy the correct length, then how easy it is to bend and twist is not important but always, the lower the "awg" the thicker the wire is and the better it is for signal transfer with less degradation.

Also the lowest cable prices I can find anywhere are at www.monoprice.com

That is where I was looking and didn't know the difference between the cables. I get it now. Thank You

Another consideration is that some downstream devices are powered by DC current which flows through the HDMI cable. Smaller gauge cable will have a greater voltage drop and may fail to power some of these devices when the length is greater. A larger cable (smaller gauge number) has less voltage drop and can power devices over longer distances better.

correct, and it often blows hdmi ports like mine!

OK-- this may be a dumb question, but I really want to know: What devices are actually powered by an HDMI power source? I understand that Pin 18 is a 5V 50 mA -- but are some devices actually POWERED from this source alone?

I do not know as of this posting but will research that issue. My incedent was when some errant dc voltage got into the line.
I was told it was due to solder breaking down
it is a wire afterall

There aren't any right now, as far as I know. The HDMI spec allows for a small amount of current over pin 18, just enough for charging a small device. There's a proposal for MHL (mobile high definition link) that would allow a TV to supply a charge to a mobile device, like a phone, to charge it while HD content is streamed from the phone to the TV.

28 AWG with Ferret Cores has wire inside that is 28 Gauge and there are metal (Ferret) rings at each end that the wire wraps around to try and reduce interference.

24 AWG has thicker 24 gauge wire in it and a metal mesh cover over the wire. The CL2 means it is rated for use in-wall
