Overview
The Cable Matters 48Gbps HDMI 2.1 Cable is a high-performance display cable fully compliant with the latest HDMI 2.1 standard. With a maximum bandwidth of 48Gbps, it reliably delivers 8K/60Hz and 4K/120Hz video signals. Ideal for pairing with gaming PCs, modern TVs, and monitors, it also supports VRR (Variable Refresh Rate) and eARC (Enhanced Audio Return Channel).
Key Features
- 48Gbps bandwidth supporting 8K/60Hz and 4K/120Hz
- Full HDMI 2.1 compliance (VRR, eARC, ALLM, DSC)
- Gold-plated connectors and triple shielding reduce interference
- 6-foot (1.8m) length suitable for desktop setups
- Backward compatible with HDMI 2.0/1.4 devices
Compatibility Guide
This cable delivers full performance with HDMI 2.1 ports on GeForce RTX 30/40 series, Radeon RX 6000/7000 series, PlayStation 5, Xbox Series X, and modern 4K/8K TVs. It works with older HDMI 2.0 devices but at reduced bandwidth. The 1.8m length is ideal for typical PC-to-monitor connections. For longer runs, consider active repeaters or optical HDMI cables.
Ideal Builds
- Gamers building 8K or 4K/120Hz high-refresh-rate setups
- Users wanting to maximize latest GPU and HDMI 2.1 monitor capabilities
- Home theater PCs (HTPC) connecting to AV receivers and TVs via eARC
- Professional video editing or content creation requiring color accuracy
Upgrade Considerations
HDMI 2.1 cables only realize their full potential with HDMI 2.1 devices; older HDMI 2.0 gear will not benefit. Signal degradation can occur over longer lengths, so for runs over 3m, optical HDMI cables are recommended. While cables rarely become bottlenecks, cheap uncertified cables may cause link instability, so choosing certified products is crucial.
