Honeywell’s self-diagnostic and self-healing HDMI cable has CURxE light technology that automatically corrects corrupted HDCP and EDID data that would otherwise degrade high definition picture and multichannel audio performance. Four LEDs integrated into the cable’s HDMI connector serve as self-diagnostic monitoring indicators. The four LEDs verify hot plug detection; +5V status; HDCP; and EDID, pointing to either downstream, upstream or device problems depending on which LED fails to light. The cable has full-balanced line transition-minimized differential signaling (TMDS); a 100 percent foil shield with 25 percent overlapping, combined with a 90 percent tinned copper braid shield; and bandwidth-maximizing silver-plated copper conductors.
