i googled and tried to understand whether i should order hdmi w/ ethernet or without. I ended up ordering regular 10 foot hdmi w/ ferrite core for $5 so hopefully this is suitable for my blu ray 3d setup with a panny ST50, is it?

Second, can anyone offer clarity on what the ethernet hdmi will do that the above won't? I read online but don't get it.

The HDMI with ethernet cable lets you connect all your gear to a network without using a separate ethernet cable for each device. Of course, the equipment the cable is attached to has to support this feature. So far, few if any devices, do. So essentially, HDMI with ethernet cables aren't required for anything.

There is an advantage to using a HDMI with ethernet cable if you are using audio return channel (ARC) with a long cable. The changes made to support ethernet also make for a better environment for ARC. IOW you might be able to get ARC to work at a longer distance than it would otherwise.

If you aren't getting sparkles or worse with your current cable, changing the cable won't make any difference.

Good question - it doesn't do anything. No manufacturer I'm aware of has implemented a chipset with "Ethernet over HDMI" capability. However, from a cable standpoint it is another indication that all the pins are connected. So it doesn't hurt for a cable but you will gain no actual Ethernet over HDMI capability.

The intent of the capability was to deliver Ethernet using your HDMI cable. The source would transcribe the signal into the HDMI stream and then transmit. I suspect this is not the easiest capability to impllment and has a doubious usefulness due to wifi and those of us who would rather use Cat 6.

Two excellent, and anticipated responses wink.gif FWIW, my High Speed cables have ethernet (no ferrite cores though, don't need them) and they work just fine. I just bought them with ethernet in case ethernet is implemented in future purchases.

Try here. Note that sparkles don't always appear as extreme as the first example. The third picture is a lower bit error rate example.
