THX® Certification involves a rigorous suite of some 75 tests over and above the HDMI® Compliance Test Specification (CTS), including tests for high bandwidth stability to 18Gbps (aggregate data rate), dependable interoperability, benchmark connector fit and overall premium build quality. It’s the most comprehensive cable test regime on the planet, certifying cables as the best available. Read more about the THX Interconnect Certification program here.

DarbeeVision Inc. is the creator of Darbee Visual Presence™ (DVP), the visual perception processing methodology as featured in their DVP-5000 Darblet and DVP-5100CIE (Custom Installer Edition) stand-alone devices, and is also integrated into the premium ‘D’ series Oppo Blu-ray players for the best possible picture quality.

Darbee have uniquely certified the Kordz R.3 HDMI cable for its robust connection, signal transfer accuracy and shielding properties. This ensures fully tested FCC (Federal Communications Commission) compliance not only at the Darbee HDMI port, but at the far end of the interconnect for high integrity delivery of the processed signal to the display.
