Gefen wants to help you push HDMI over a distance as well as offering control from a remote source. It is introducing its HDMI RS-232 CAT-5 Extender for around $600.
The Gefen HDMI RS-232 CAT-5 Extender lets one adjust their displays, change settings and access audio/video sources from up to 50 meters (150-feet) in distance. Sender and receiver units connect the A/V source to the remote display using category-5 cables that transmit 1080p full HD resolutions as well as RS-232.
Gefen says installation of the system is simple, requiring a local connection of the A/V and RS-232 equipment to the sender, and the display to the receiver. Source connection cables are included in the package.Cat-5, Gefen, HDMI, HDMI Extender, home theatre
