Key Digital Introduces Next Generation Fixer for 4K/18G Digital Video Installations 

KD-FIX418 corrects 4K/18G HDMI connectivity problems  

Mount Vernon, NY – March 26, 2018 – The award winning manufacturer of professional A/V and Control systems introduces the KD-FIX418, a compact HDMI correction device for 18G HDMI video signals. The KD-FIX418 resolves common HDMI integration obstacles related to HDCP, EDID, Hot Plug Detection, and bandwidth. Units may be paired to compress and decompress 18Gbps video signals and extend via legacy 10.2Gbps cabling, or high-equalization may be applied on the HDMI input for repair of degraded incoming signals.  

The KD-FIX418 is a simple yet powerful correction device with many different modes to help integrators fix 18G HDMI video signal problems. In down-convert mode the unit accepts an incoming 18G signal and down-converts into a 10G signal for integration into an existing matrix or video distribution system. Another mode compresses 18G signals for extension over a long HDMI cable and then decompresses the signal with a second KD-FIX418 unit installed near the display. With compression and decompressed modes selected, the 18G signal is able to extend over existing infrastructure and still be displayed at 18G. Lastly, it also has high-input boost to clear up any issues with artifacts on the display such as lost pixels or flickering. The different modes are selected using a small rotary conveniently located next to the HDMI connecter on the unit. 

The KD-FIX418 works with HDMI cabling for extension of 4K/UHD signals with HDR10 up to 75 ft / 23m in or out, and offers 4K/UHD support for 4096x2160 or 3840x2160 24/25/30/60hz at 4:4:4(up to 18Gbps bandwidth).    

KD-FIX418 also has built—in Full Buffer System technology which manages TMDS re-clocking and signal re-generation, HDCP authentication to source & display, and EDID handshaking control. Unlike many manufacturers, Key Digital has had EDID control for 10+ years. EDID control has 15 different settings inside the software, many of which are now updated to contain HDR header information in the handshake. HDCP authentication on the HDMI input gives the source the information and file it needs and is 2.2 compliant. Forced Hot Plug Detection enables the integrator or user to choose if the active signal voltage is forced to the connected input device.
