Just to clarify a bit...Version numbers should never be used with HDMI cables. There is no such thing as an HDMI 1.4 cable.
HDMI Org owns the trademarks, copyrights, patents and specifications for HDMI. So they should know.
The HDMI 1.4 specification included much more than just HDMI with Ethernet. However, that doesn't matter since there are only two types of HDMI cables - High Speed and Standard Speed. Each type has a number of options, including "with Ethernet". The humorous part is that no manufacturer that I know of has yet to release piece of equipment that uses the HDMI with Ethernet capability. Just because a device has HDMI and allows Ethernet to be input, doesn't mean that the devices uses HDMI with Ethernet and, in fact, none do.
So what you are looking for is a certified High Speed HDMI cable. If you want to include the "with Ethernet" option that's fine too. However, if you find someone who is selling an HDMI 1.4 cable, you should probably look elsewhere since that type of branding/advertising is forbidden by the HDMI Org and might be a counterfeit cable. eBay seems to be full of counterfeit HDMI cables which claim to be High Speed but are actually just Standard Speed cable with a version number slapped on top.
