9.8ft Certified Ultra High Speed HDMI 2.1 Cable
This 9.8ft (3m) male-to-male HDMI cable is certified for the Ultra High Speed HDMI 2.1 standard. It supports 48Gbps bandwidth for 8K 60Hz and 4K 120Hz video. The cable suits installers and home users who need a reliable passive link between source devices and 8K displays. Gold-plated connectors and a flexible TPE jacket complete the assembly.
Practical Limits of the 48Gbps Passive Interface
The passive design delivers full 48Gbps performance at this 3m length without external power. Operation is rated from 0°C to 50°C with humidity up to 85% RH. The aluminium-mylar foil and braid shielding protects signal integrity against EMI. Durability testing covers 10000 insertions and 600 bend cycles at 120°. Buyers needing longer runs beyond the certified passive limit should consider active or fibre alternatives.
48Gbps Certification Decides 8K Suitability
The Ultra High Speed HDMI 2.1 certification is the single specification that confirms this cable handles uncompressed 8K 60Hz (7680 x 4320) and 4K 120Hz signals. It also carries 32-channel audio, 7.1-channel audio, eARC, Dolby Vision, HDR10+ and HDCP 2.3. If your installation requires certified 48Gbps throughput at 3m, this part meets that requirement.

Questions about this item
Should I pick the 9.8ft length or look for a shorter cable for my 8K setup?
The 9.8ft (3m) length is within the certified Ultra High Speed HDMI 2.1 specification for full 48Gbps bandwidth. If your source and display are closer, a shorter cable reduces clutter, but this length will still deliver 8K 60Hz and 4K 120Hz without signal loss.
Will the 48Gbps rating actually give me 8K 60Hz on my TV and graphics card?
Yes. The cable is certified Ultra High Speed HDMI 2.1, so it supports the full 48Gbps data rate required for 8K 60Hz (7680 x 4320), 4K 120Hz, Dynamic HDR10+, Dolby Vision and eARC audio formats like Dolby Atmos and DTS:X.
Does the HDMI 2.1 interface cap anything when I use this cable with my monitor?
The HDMI 2.1 interface on this passive cable caps the maximum digital resolution at 8K 60Hz and the data rate at 48Gbps. It also carries 32-channel audio, 7.1-channel audio, HDCP 2.3 and eARC, so your monitor’s own HDMI 2.1 port determines the final limit.
