About HDMI 2.0
The HDMI standard was created to transfer uncompressed digital audio and video. HDMI cable’s many internal conductors include communication channels, which allow automatic display and source matching for resolution, format and aspect ratio.
“Standard Speed” HDMI cable will, at-minimum, transfer 1080i, 720p, 1080p/30Hz source material.
“High Speed” HDMI cable will, in addition, transfer 1080p/120Hz, 4K, 3D video.
“With Ethernet” HDMI cable (with HEC) includes conductors for bi-directional Ethernet communication. Ethernet capability is independent of “Speed” capability.
SOLID LONG-GRAIN COPPER (LGC) CONDUCTORS: Solid conductors eliminate strand-interaction distortion. Slinky’s solid Long-Grain Copper allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. OFHC is a general metal industry specification regarding “loss” without any concern for distortion. LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively better performance.
GEOMETRY STABILIZING SOLID-POLYETHYLENE INSULATION: Reduces smearing and preserves dynamic contrast.
HIGH SPEED DATA CAPACITY: All AudioQuest HDMI cables up to 8 meters meet or exceed the 18 Gbps maximum data rate for HDMI and are approved High Speed with Ethernet cables. This means that all AudioQuest cables up to 8 meters are capable of transmitting 100% of the data required for all of HDMI’s current audio/video features including multichannel high-resolution audio, 1080p and 4K video, and 3D video from Blu-ray. All AQ HDMI cables will deliver 100% of the data required for 120Hz/240Hz/600Hz displays.
ETHERNET AND AUDIO RETURN CHANNEL ENABLED: All AudioQuest HDMI cables up to 8 meters are rated High Speed with Ethernet. From 12 meters to 20 meters AudioQuest HDMI cables are Standard Speed with Ethernet.
DIRECTIONALITY: All audio cables are directional. The correct direction is determined by listening to every batch of metal conductors used in every AudioQuest audio cable. All signal conductors controlled for digital-audio direction in AudioQuest HDMI cables, and care is even taken to run the conductors used in the Audio Return Channel in the opposite direction to ensure the best performance for that application. Arrows are clearly marked on the connectors to ensure superior sound quality.
