Gefen has upgraded its HDMI range extender and now enables 1080p full HD with 3DTV pass-through to be transmitted over just one CAT5 cable instead of two. The range remains at 330 feet or 100m.
Data input and output on both ends is provided via a USB 2.0 interface with the signal being transferred over a standard Ethernet cable. According to the manufacturer, the "HD KVM ELR" is primarily targeted at "post-production editing suites, where computers are isolated in machine rooms or closets, and hi-def video with keyboard/mouse peripherals are extended to the edit room."
The HD KVM ELR is not cheap at $1,000, but it is a unique solution given the fact that the longest HDMI cables with signal boosters currently reach just 100 ft in length. Those cables can be purchased for less than $100, but if you need to bridge greater distances than 100 ft, the HD KVM ELR may be an interesting solution.
