AudioQuest 18Gbps High Speed HDMI cables have the bandwidth required for video up to 8K/30 (8-bit, 4:2:0), which is 7680 x 4320 resolution (over 33 million pixels) at up to 30 frames-per-second (fps). 24 and 30 fps are the frame rates for almost all movies and many TV shows.
HDMI hardware’s previous ARC capabilities max out at lossy (compressed) 5.1-channel surround sound. Not only do all generations of AudioQuest HDMI cables “with Ethernet” support ARC, but in order to ensure superior audio performance, the ARC-channel conductor-pair is internally controlled for direction, running in the opposite direction from the 4 pairs that carry information to the TV. Upcoming HDMI 2.1 hardware supports Enhanced Audio Return Channel (eARC), which increases bandwidth dramatically to support uncompressed and lossless high-resolution multichannel audio, including Dolby TrueHD and Atmos, and DTS-HD Master Audio and DTS: X. All AudioQuest HDMI cables “with Ethernet” have the conductors and bandwidth required for eARC’s enhanced sonic capabilities.
All AudioQuest 18Gbps High Speed HDMI cables are guaranteed to have the 18Gbps bandwidth required for compelling features like 8K/30 video, HDR (High Dynamic Range) imagery, and eARC (enhanced Audio Return Channel).
AudioQuest 18Gbps High Speed HDMI cables support High Dynamic Range (HDR) and Dynamic HDR. HDR content expands the contrast of the image for blacker blacks and brighter whites/highlights as well as greater color saturation and brightness. Dynamic HDR (HDR 10+ and Dolby Vision for example) enables frame-by-frame HDR optimization rather than HDR settings that are fixed for the entire program.

- SOLID LONG-GRAIN COPPER (LGC) CONDUCTORS
Solid Long-Grain Copper (LGC) allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. Solid conductors prevent strand interaction, a major source of distortion. The surface quality is critical because a conductor can be considered as a rail-guide for both the electric fields within a conductor, and for the magnetic fields outside the conductor. LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively better performance.
All drawn metal strands or conductors have a non-symmetrical, and therefore directional, grain structure. AudioQuest controls the resulting RF impedance variation so that noise is drained away from where it will cause distortion. The correct direction is determined by listening to every batch of metal conductors used in every AudioQuest audio cable. When applicable, arrows are clearly marked on the connectors to ensure superior sound quality. For most models of AQ cable, the arrows not only indicate the direction that optimizes metal-directionality as part of Noise-Dissipation, but also indicates non-symmetrical attachment of shield and GND in order to optimize full-system performance.
- HIGH SPEED DATA CAPACITY
HDMI standards and capabilities have improved significantly since DVI first evolved into HDMI. All generations are backward compatible. However, not all previous HDMI cables can transmit the full 18Gbps of data required to optimize today’s HDMI 2.0 equipment. While there is currently no 4K/60 4:4:4 software requiring the full 18Gbps capability of HDMI, some sources (UHD Blu-ray players) can be set to “up-sample”, requiring 18Gbps capability. Up-sampling often should be done in the TV rather than in a previous component — but that’s your decision. AudioQuest HDMI cables with “Exceeds 18 G bps” on the box front are guaranteed to exceed the requirements for all possible HDMI data streams.
