18Gbps Blueberry 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).

Video Up to 10K 48Gbps HDMI cables are completely backwards compatible with existing devices and have the bandwidth required for video with resolutions up to 10K and resolutions/refresh rates up to 8K/60 and 4K/120. HDR (High Dynamic Range) All AudioQuest HDMI cables support HDR (High Dynamic Range) 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. In addition, 4K Ultra-HD content allows for a wider color range. This combination of technologies results in more realistic HDR images with greater perceived depth.

Dynamic HDR (HDR10+ and Dolby Vision, for example) enables frame-by-frame HDR optimization rather than HDR settings that are fixed for the entire program. The most prominent current HDR formats are HDR10, HDR10+, and Dolby Vision.

AudioQuest 18Gbps and 48Gbps HDMI cables are compatible with all varieties of HDR, which can be found on Ultra-HD Blu-ray, and all major streaming services, including Netflix, Amazon Prime, Disney+, Apple TV+, and others.

ARC (Audio Return Channel) and eARC (enhanced Audio Return Channel) HDMI's Audio Return Channel (ARC) sends audio from a TV to a soundbar or AV receiver for greater simplicity and flexibility in system setup. Hardware's previous ARC capabilities max out at lossy (compressed) 5.1-channel surround sound.

Today's HDMI 2.1 hardware supports enhanced Audio Return Channel (eARC), which increases the digital bandwidth dramatically to support uncompressed and lossless high-resolution multichannel audio, including Dolby TrueHD and Atmos, and DTS-HD Master Audio and DTS: X.

Not only do all current generations of AudioQuest HDMI cables have the conductors and bandwidth required for eARC's enhanced sonic capabilities, 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.
