3ft Ultra High Speed 8K HDMI 2.1 Cable, Certified 48Gbps for 4K 120Hz Gaming, UL, Black

The Ultra High Speed 8K HDMI 2.1 Cable connects two HDMI Type A devices and carries the HDMI Forum Ultra High Speed Certification, confirming a true 48Gbps bandwidth for 8K@60Hz and 4K@120Hz video. At 48Gbps it more than doubles the 18Gbps ceiling of an HDMI 2.0 cable, which is the difference that unlocks 8K and high-refresh 4K. It targets next-generation gaming consoles, high-refresh PC monitors and 8K-ready home theater setups that demand the full HDMI 2.1 signal path rather than a relabeled HDMI 2.0 cord.

Both ends terminate in a 19-pin HDMI Type A male connector with gold-plated contacts that resist oxidation and maintain low contact resistance across thousands of mating cycles. The molded strain relief and 85% braided shield protect the high-bandwidth pairs where the cable bends at a console, monitor stand or AV receiver, keeping the signal chain stable in tight desktop and rack layouts.

Inside, stranded bare copper signal conductors (pure copper, not copper-clad aluminum) carry the 48Gbps payload with stable signal integrity, paired with aluminum foil and braid coverage that limits electromagnetic interference and crosstalk. This construction supports uncompressed 8K@60Hz, 4K@120Hz, eARC, VRR, ALLM and Dynamic HDR without compression artifacts or dropped frames.

Every cable is HDMI Forum Ultra High Speed Certified with an anti-counterfeit label and QR code that can be verified at HDMI.org, and the jacket is UL recognized (E515987), VW-1 flame rated, and RoHS and REACH compliant. These marks separate a genuine certified 48Gbps cable from uncertified cords that print "2.1" without passing the certification testing that guarantees bandwidth.

For gaming, the cable drives 4K@120Hz and VRR on PS5 and Xbox Series X, and high-refresh 1440p and 4K on 120Hz, 144Hz and 240Hz monitors, removing the frame drops and signal loss that under-spec cords introduce. For home theater, it carries 8K@60Hz to 8K televisions and passes lossless audio to eARC soundbars and AV receivers, making it a single short-run cable for both desktop and living-room signal chains.

This passive copper cable is built for short desktop, console and living-room runs and is available in 3, 6, 10 and 15 ft lengths. It is compatible with PS5, Xbox Series X/S, Apple TV, Roku, 4K and 8K TVs, gaming monitors, AV receivers and high-end GPUs that output an HDMI 2.1 signal. For long-distance 8K runs through walls, conduit or to a projector, pair it with the Cable Leader 8K HDMI active optical (AOC) fiber series instead.

Product Comparison: 8K HDMI 2.1 vs Standard 4K HDMI 2.0

Both cables use identical HDMI Type A connectors, so they look the same until you check the certification and bandwidth. Only an Ultra High Speed (HDMI 2.1) cable passes the full 48Gbps needed for 8K and 4K@120Hz. Use the table below to confirm which cable your display and source actually require.

FAQ

What is the difference between an HDMI 2.1 cable and an HDMI 2.0 cable?

An HDMI 2.1 Ultra High Speed cable carries 48Gbps versus 18Gbps on HDMI 2.0, which is what enables 8K@60Hz and 4K@120Hz. HDMI 2.0 cables top out around 4K@60Hz and cannot pass the full 8K or high-refresh signal even if the connectors look identical.

Is this cable compatible with PS5, Xbox Series X and 4K 120Hz gaming monitors?

Yes. The certified 48Gbps bandwidth supports 4K@120Hz and VRR on PS5 and Xbox Series X, and high-refresh output to 120Hz, 144Hz and 240Hz monitors. It is fully backward compatible, so it also works with any standard HDMI Type A device, such as a 4K@60Hz TV or laptop, at lower resolutions.

What HDMI cable do I need for 4K@120Hz or 8K@60Hz?

You need an Ultra High Speed HDMI cable rated for the full 48Gbps, not a High Speed or Premium High Speed (HDMI 2.0) cable. This cable is HDMI Forum certified for 48Gbps, so it passes 8K@60Hz and 4K@120Hz uncompressed. A connector that looks like HDMI 2.1 is not enough; the cable itself must carry the bandwidth.

How can I tell this is a genuine certified HDMI 2.1 cable?

Each cable carries the HDMI Forum Ultra High Speed Certification label with an anti-counterfeit QR code. Scanning that code with the HDMI Cable Certification app at HDMI.org confirms the cable passed 48Gbps testing, which uncertified "2.1" cables cannot show. The Ultra High Speed wordmark alone is not proof; the verifiable QR label is.

Which 8K HDMI cable is best for a long run to a projector?

For runs over about 15 ft, choose an 8K HDMI active optical (AOC) fiber cable rather than this passive copper cable. This copper version is optimized for short desktop, console and living-room runs from 3 to 15 ft, where it stays fully passive and bi-directional.
