Well, standard cables are also 1.4 compliant, but may not support 3D. So, a cable labelled 1.4 won't necessarily work. In the real world. Fortunately, the OP had a cable correctly labelled high speed.
In general, I think these forums should elevate the understanding of AV issues, not lower them. What's your beef with HDMI.org trying to clarify the actual differences in cables? There's been a common misconception that people need to waste money on new cables whenever there's an HDMI update. Nothing in 1.4 requires new cables except for Ethernet, which is rarely used.
