This article covers Monoprice 8K 超高速HDMIケーブル.

Overview

The Monoprice 8K Ultra High Speed HDMI Cable is a fully certified HDMI 2.1 cable capable of 48Gbps bandwidth. It supports 8K at 60Hz and 4K at 120Hz, making it ideal for next-gen gaming consoles (PS5, Xbox Series X) and high-end PCs. With support for Dynamic HDR, eARC, VRR, and Dolby Vision, this 15-foot (4.57m) cable bridges your devices without compromising on quality. Whether you're setting up a gaming rig or a home theater, this cable ensures you get the full HDMI 2.1 experience.

Connectivity & Compatibility

This cable fully complies with HDMI 2.1 specifications, so it works seamlessly with PS5, Xbox Series X/S, PC graphics cards (GeForce RTX 30/40, Radeon RX 6000/7000), and AV equipment. It is backward compatible with HDMI 2.0 and earlier devices, making it a future-proof choice. The eARC support delivers high-quality audio from your TV to a soundbar or AVR. Gold-plated connectors and braided shielding minimize signal interference, ensuring reliable performance over the 15-ft length.

Product Info

Monoprice introduced this 8K Ultra High Speed HDMI cable around 2022. Priced at ¥4,840 on Japan (as of June 2026), it offers excellent value compared to similarly specced cables from premium brands. The cable comes with a standard Monoprice warranty (typically one year) and includes only the cable itself. You can purchase it directly from Japan or the Monoprice official store.

Best Use Cases

Gamers with 8K TVs or 4K/120Hz monitors: use this cable to unlock full HDMI 2.1 features like VRR and high refresh rates. Home theater enthusiasts: the long 15-ft run is perfect for connecting a projector or TV to a receiver, and eARC simplifies audio routing. Professional content creators requiring high-bandwidth display connections: 48Gbps ensures zero compression for color-critical work. Not ideal for users still on HDMI 2.0 devices who don't need future-proofing – a standard High Speed cable will suffice.
