I've never heard of a 3D HDMI cable. Sounds like a marketing term.
You should have an HDMI 1.4 cable. I'd avoid anyone calling it a "3D HDMI cable." Plenty of respectable sources for 1.4 cables, such as Monoprice. You probably have only HDMI 1.3 cables. Yes, there is a difference. Will you visually notice? ........
Okay thanks. I was on dishnetwork site and they had a 3D HDMI cable listing that's why I was asking if they made a 3D cable or not. Was under they 3D programming I think.
Hmmm. Per HERE they aren't supposed to list cables as 1.3 or 1.4. The classifications are: Standard, Standard with Ethernet, Standard Automotive, High Speed and High Speed with Ethernet. A High Speed should work for 3D. Standard may work for short lengths.
And yes, I now see Monoprice lists them correctly- e.g. "High Speed."
