3ft Certified Ultra High Speed HDMI 2.1 Cable with 48Gbps Bandwidth, 8K 60Hz and 4K 120Hz Video, HDR10+, Dolby Vision, eARC, HDCP 2.3, Gold-Plated Connectors, and Lifetime Warranty
The StarTech HDMM21V1M is a 3-foot (1 m) Certified Ultra High Speed HDMI 2.1 cable that supports 8K at 60 Hz and 4K at 120 Hz with 48 Gbps of bandwidth for next-generation displays, gaming consoles, and media devices. The HDMI 2.1 Male-to-Male cable carries 7680 x 4620 resolution with HDR10+ and Dolby Vision high-dynamic-range video, plus eARC (Enhanced Audio Return Channel) with 32-channel uncompressed audio including Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio, and DTS:X.
Ultra High Speed HDMI certification from an HDMI Authorized Test Center confirms the cable meets the full 48 Gbps bandwidth specification and passes dedicated EMI testing. HDCP 2.3 content protection supports protected 4K and 8K content from streaming services and Blu-ray players. Gold-plated 19-pin connectors in die-cast aluminum housings resist corrosion and block electromagnetic interference, and the 30/32 AWG conductors are wrapped in aluminum-mylar foil and braid shielding. The flexible TPE jacket withstands 10,000+ insertions and 600+ bend cycles at 120 degrees, backed by StarTech's lifetime warranty.
Where the HDMM21V1M Fits
- Gaming setups with PS5, Xbox Series X, or high-refresh PC monitors where 4K at 120 Hz delivers the full frame rate that current consoles and GPUs can output, the 3-foot length keeps the cable run tight between a console and a desk or entertainment center display, and 48 Gbps bandwidth leaves headroom for VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode)
- Home theater and media rooms where 8K 60Hz and 4K HDR10+ content from streaming devices, media players, and UHD Blu-ray players passes through to 8K or 4K displays, eARC delivers lossless Dolby Atmos and DTS:X surround sound to compatible receivers, and HDCP 2.3 supports protected premium content without handshake errors
- Professional AV and digital signage where 8K source devices connect to commercial displays or projectors for presentations, video walls, and signage, the certified 48 Gbps link eliminates sparkle artifacts and signal dropouts at high resolutions, and the 10,000+ insertion rating handles daily cable changes in shared conference and event spaces

Do You Need a Special Cable for HDMI 2.1?
HDMI 2.1 features like 4K at 120 Hz, 8K at 60 Hz, and eARC require a cable rated for 48 Gbps of bandwidth. Standard High Speed HDMI cables (rated at 18 Gbps for HDMI 2.0) physically cannot carry enough data for these resolutions and refresh rates. An Ultra High Speed Certified cable like the HDMM21V1M has been tested at an HDMI Authorized Test Center to confirm it delivers the full 48 Gbps specification. Without certification, a cable may be labeled "HDMI 2.1 compatible" but fail to maintain a stable signal at 4K 120 Hz or 8K, resulting in sparkle artifacts, black screens, or dropped frames. The certification label on the cable packaging includes a QR code that links to the HDMI.org verification database.
