Belkin Ultra High Speed HDMI 2.1 Cable — 2 m, Black
HDMI 2.1 Certified8K@60Hz / 4K@120Hz48 Gbps bandwidtheARC, VRR, Dolby Vision
The Belkin Ultra High Speed HDMI 2.1 cable (part number AV10175BT2MBKV2) is a certified HDMI 2.1 cable, 2 m / 6.6 ft long, with 19-pin HDMI Type A male connectors at both ends. Certification is the point of it: the Ultra High Speed programme tests each cable design against the full 48 Gbps HDMI 2.1 specification, so 8K at 60 Hz and 4K at 120 Hz are guaranteed rather than claimed. It carries eARC for uncompressed audio back to a soundbar or AV receiver, VRR and ALLM for tear-free console gaming, and Dolby Vision and HDR10 for high dynamic range. Plug-and-play with a PlayStation 5, Xbox Series X, Apple TV, MacBook, media player or set-top box — anything with an HDMI socket.
Compatibility — check before buying:
This is a standard HDMI Type A cable and works with any HDMI device, but the 8K and 120 Hz modes need both ends to support HDMI 2.1 — a PS5 or Xbox Series X into an HDMI 2.1 television or monitor, for example. On older HDMI 2.0 equipment the cable simply runs at whatever that equipment supports, so it is safe to buy ahead of an upgrade. HDMI cables are directional in practice only over long runs; at 2 m either end can go into the source.
Best For
✓ PlayStation 5 and Xbox Series X owners who want 4K at 120 Hz
✓ Anyone connecting an 8K television or monitor
✓ Home cinema setups using eARC to a soundbar or AV receiver
✓ Apple TV, MacBook and media-player users who want Dolby Vision
✓ People replacing an unlabelled cable that drops out or flickers
✓ Anyone who wants certification rather than marketing claims
Key Features
HDMI 2.1 Certified, not just labelled
Certification means the design was tested against the full HDMI 2.1 Ultra High Speed specification. An uncertified “8K” cable can pass 4K and fail at high bandwidth — usually as sparkles, black flashes or a signal that drops out under load.
48 Gbps for 8K@60Hz and 4K@120Hz
The full HDMI 2.1 bandwidth, which is what 8K at 60 Hz and 4K at 120 Hz actually require. That is the difference between a console running at 120 Hz and one quietly falling back to 60.
eARC for uncompressed audio
Enhanced Audio Return Channel sends high-bitrate audio — Dolby TrueHD, DTS:X, Dolby Atmos — from the television back to a soundbar or receiver over the same cable. Ordinary ARC compresses it.
VRR, ALLM and Dolby Vision
Variable Refresh Rate removes screen tearing on consoles, Auto Low Latency Mode switches the television into game mode by itself, and Dolby Vision plus HDR10 carry the wider colour and contrast range.

Frequently Asked Questions
Do I need an HDMI 2.1 cable for a PS5?
For 4K at 120 Hz, yes. A PS5 or Xbox Series X will output 4K at 60 Hz over an older cable, but the 120 Hz modes need the full 48 Gbps bandwidth this cable is certified for.
Will it work with my older 4K TV?
Yes. It is fully backward compatible — on HDMI 2.0 equipment it runs at whatever that equipment supports. Buying it now means the cable will not need replacing when the television does.
What does “Ultra High Speed Certified” mean?
It means the cable design passed HDMI Licensing Administrator testing for the complete HDMI 2.1 feature set. Cables that merely print “8K” on the bag have not been through that.
Does it carry Dolby Atmos to my soundbar?
Yes, through eARC. The television sends the uncompressed audio back down this cable to a soundbar or AV receiver that also supports eARC.
Singular Expert Insight
Most HDMI problems people blame on a television or a console are cable problems: an uncertified cable will happily pass 4K at 60 Hz and then produce sparkles or dropouts the moment you switch a PS5 to 120 Hz. Certification is the whole value here — it is a tested guarantee of 48 Gbps rather than a number on the packaging. Two metres is the practical length for a console or a media player sitting under the television; longer runs raise the bar on cable quality considerably. See the rest of our
HDMI cables and adapters if you need a different length. Our wider
cables range covers DisplayPort, USB-C video and adapters if the source uses something other than HDMI.
Buyer's Guide
Buy it if
You have an HDMI 2.1 source — PS5, Xbox Series X, 8K TV, recent Apple TV — and you want the full 8K/120 Hz, eARC and VRR feature set with certification behind it.
Skip it if
Your equipment is HDMI 2.0 and staying that way, and you only need 4K at 60 Hz — a cheaper High Speed cable will do that.
Also consider
A longer or shorter run from the same certified range if 2 m does not fit your setup, and a soundbar or receiver with eARC to make use of the uncompressed audio return.
