4K/8K

AudioQuest 18Gbps High Speed HDMI cables have the bandwidth necessary for video up to 8K/30 (8-bit, 4:2:0), which is a resolution of 7680 x 4320 (over 33 million pixels) with up to 30 frames per second (fps). 24 and 30 fps are the frame rates for almost all movies and many TV shows.18GAll AudioQuest 18Gbps High Speed HDMI cables guarantee the 18Gbps bandwidth necessary for attractive features such as 8K/30 video, HDR (High Dynamic Range) images, and eARC (Enhanced Audio Return Channel).

LEVEL 4 NOISE-DISSIPATION: GALVANIC ISOLATION + SIGNAL DIRECTION

Traditional "100% shielding" is not enough to protect against the increasingly common effects of Wi-Fi, Bluetooth, 4G/5G, and satellite radiation. In AudioQuest HDMI cables, all 19 conductors are directionally controlled to minimize RF noise that impairs performance by diverting it away from the most vulnerable circuits. Level 4 Noise-Dissipation includes non-conductive fibers that are immune to induced RF noise, while the eARC and control conductors are made of directionally controlled metals. Additional noise-dissipation techniques (Level 4+ and higher) are applied if the budget allows for further noise reduction.

eARC

Previous ARC capabilities of HDMI hardware stopped at "lossy" compressed 5.1-channel surround sound. Not only do all generations of AudioQuest HDMI cables "with Ethernet" support the ARC signal, but the eARC conductor pairs that run in opposite directions are also signal direction controlled to ensure superior audio performance. HDMI 2.1 hardware supports Enhanced Audio Return Channel (eARC), which dramatically increases bandwidth to pass 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 necessary for the greatly improved sound quality of eARC.

HDR

AudioQuest 18Gbps High Speed HDMI cables support High Dynamic Range (HDR) and Dynamic HDR. HDR content increases the contrast of the image for deeper blacks and brighter whites/highlights, as well as greater color saturation and brightness. Dynamic HDR (such as HDR10+ and Dolby Vision) allows for frame-by-frame HDR optimization instead of HDR settings that are fixed for the entire program.

Lifetime Warranty under conditions

AudioQuest HDMI cables are precision-manufactured to ensure a high level of reliability and are covered by a non-transferable, limited lifetime warranty. Proof of original purchase is required; other restrictions apply.
