Overview

The Monoprice 138642 DynamicView Series Ultra 8K High-Speed HDMI Cable is a 1-foot HDMI 2.1 cable built to handle the most demanding audio and video signals available today. With 48Gbps of bandwidth, it supports resolutions up to 8K at 60Hz and 4K at 144Hz, along with Dynamic HDR for scene-by-scene color and contrast optimization. It also includes support for VESA Display Stream Compression 1.2a and BT.2020 wide color gamut, ensuring compatibility with the latest display standards.

For gamers, the cable supports Variable Refresh Rate (VRR), Quick Frame Transport (QFT), and Game Mode VRR, reducing input lag and screen tearing with compatible consoles and displays. On the audio side, eARC (Enhanced Audio Return Channel) and support for up to 32 audio channels at 1536kHz sampling rates mean this cable can carry the most advanced object-based audio formats back to a soundbar or AV receiver. The short 1-foot length makes it ideal for clean, clutter-free connections between closely positioned devices such as a gaming PC and monitor, a streaming device and TV, or rack-mounted AV equipment. Full backwards compatibility with HDMI 2.0 and 1.4 ensures it works with older gear as well.
