Hi, this video shows you how to use the HDMI over Ethernet Cable adaptors to extend a HDMI signal using CAT6 cables.
In the video I refer to 'HDMI over Ethernet' as most people call these cheap adapters that BUT really 'HDMI over Ethernet' would mean 'HDMI over IP' which is a different and more expensive product and these cheap adapters would be better called HDMI over twisted pair adapters or HDMI over CAT5E/6 adapters.
In the video I use them to connect up to a PC to TV and also a Roku media player to TV. They are useful if you already have network cabling in place or if you don't want to drill big holes to install the thicker HDMI plugs/cables. If you get good ones then they will work over greater distances than HDMI cables but the versions in the videos are the cheapest available and unfortunately the advertised distance of 30m did not happen so I used 15m Ethernet cables instead and they work very well. They are very easy to use and just work as soon as you plug them in. No drivers or downloads are needed.
Many thanks Vince
