This article covers Anker HDMI 2.1ケーブル.

Overview

The Anker HDMI 2.1 Cable delivers a massive 48Gbps bandwidth, making it a future-proof choice for 8K@60Hz and 4K@120Hz content. Whether you're connecting a next-gen console, a streaming box, or a high-end PC to a compatible display, this cable ensures you get the full visual fidelity without compression or signal dropouts. At 2 meters in length, it's versatile enough for both living room entertainment centers and desktop monitor setups. It's one of the first cables to receive official certification from the HDMI Forum, which adds a layer of quality assurance that generic cables often lack.

Best Use Cases

Owners of 8K TVs or 4K@120Hz monitors: If you've invested in a high-end display, this cable ensures you're not bottlenecked by bandwidth. It's especially useful for PC gamers running at 4K@120Hz or 8K@60Hz. Console gamers with PS5 or Xbox Series X: Take full advantage of 4K@120Hz gaming, VRR (Variable Refresh Rate), and ALLM (Auto Low Latency Mode) for a smoother, more responsive experience. * Home theater enthusiasts: With eARC support, you can pass lossless Dolby Atmos and DTS:X audio from your TV to a soundbar or AV receiver, creating a truly immersive audio setup. If your devices are limited to HDMI 2.0 (4K@60Hz max), a cheaper standard cable will suffice. This cable is overkill for older hardware.

Things to Consider

The cable is fixed at 2m. For longer runs (e.g., ceiling-mounted projector), look for 5m or 10m variants. To achieve 8K@60Hz or 4K@120Hz, both the source device and the display must support those resolutions and refresh rates. One-sided support won't work. Full HDMI 2.1 feature set (VRR, ALLM, DSC, etc.) requires end-to-end HDMI 2.1 compatibility across all devices in the chain. The braided nylon jacket is durable, but avoid sharp bends or running the cable under heavy furniture to prevent internal damage. ## FAQ
Q: Can this cable do 4K@120Hz on PS5? A: Yes. PS5 supports HDMI 2.1, and this cable enables 4K@120Hz output. Just make sure your TV or monitor also supports 4K@120Hz input, and that the game itself runs at that frame rate. Q: What's the real difference between this and a cheap HDMI cable? A: Bandwidth. Standard HDMI 2.0 cables top out at 18Gbps, while this one handles 48Gbps. That extra headroom is essential for 8K and high-refresh-rate 4K. Additionally, the HDMI Forum certification means it's been tested for EMI compliance, reducing the risk of wireless interference. Q: Will it work with my old HDMI 1.4 devices? A: Yes, it's fully backward compatible. Connected to an HDMI 1.4 device, it will operate at that device's maximum supported resolution and refresh rate (e.g., 4K@30Hz).
