The DPL Enhanced 48Gbps Reference Standard is an independent compliance programme that verifies a cable’s electrical performance across the full 48Gbps bandwidth required by HDMI 2.1. It assesses not only data rate but also interoperability, ensuring the cable performs reliably with a wide range of source, sink and intermediary devices. For integrators, this certification confirms that Kordz R.4 48Gbps Rack and Marine Passive HDMI Cable operates within the performance envelope needed for uncompressed 8K formats and advanced HDMI 2.1 features such as eARC, (enhance Audio Return Channel), VRR (Variable Refresh Rate) and QMS (Quick Media Switching).
