HDMI signal faces two challenges in professional AV installations: the cable runs are long, and the signal is often patched through an AV faceplate. Long cables weaken the signal as it passes through, and faceplates introduce joins which also weaken signal. Add to this some laptops output a weak signal, and some displays are more sensitive to weak incoming signal. 

Vision's 8K cables are designed for exactly these hostile conditions. They have thick conductors so there is no bandwidth bottleneck, and they are well shielded. As our longest HDMI cable, it is particularly difficult to maintain signal strength, so joining it to a faceplate module will drop the maximum resolution to 4K @ 30 Hz.
