SMUGDESK DisplayPort 2.1 Cable

This SMUGDESK DisplayPort 2.1 cable carries VESA certification and delivers up to 40Gbps bandwidth over a 3.3FT length. It supports resolutions including 8K at 60Hz, 4K at 144Hz and 2K at 240Hz with HDR10. The cable is backwards compatible with DisplayPort 1.4, 1.3, 1.2 and earlier versions.

Gamers and creators needing high refresh rates

The cable suits users driving 4K monitors at 120Hz or 144Hz and 2K displays at 165Hz or 240Hz, plus multi-stream transport for daisy-chained screens. It also passes 32 audio channels for 7.1 or 5.1 surround sound. Buyers who need longer runs beyond 3.3FT or who require locking connectors should look at alternative cable designs.

40Gbps bandwidth with DSC 1.2a headroom

The 40Gbps link comfortably handles 8K at 60Hz and 4K at 144Hz using Display Stream Compression 1.2a, while leaving margin for HDR metadata and 32-bit audio. At the upper limit, uncompressed 8K at higher refresh rates would exceed the available bandwidth, so the cable relies on DSC for those top-tier modes.

Questions about this item

Does my graphics card and monitor both need DisplayPort 2.1 ports to use this cable?

The cable works with any DisplayPort source and sink; it is backwards compatible with DisplayPort 2.0, 1.4, 1.3, 1.2, 1.1, 1.1a and 1.0, so older ports will still function at their native limits.

Will this cable run at full 40 Gbps bandwidth on my DisplayPort 1.4 monitor?

Bandwidth is limited by the lowest DisplayPort version in the chain; a 1.4 monitor caps at HBR3 speeds, so the cable will carry 1.4 signals reliably but cannot exceed the monitor's capability.

How can I verify the cable is delivering 8K at 60 Hz with HDR after I connect it?

Open the monitor OSD or GPU control panel and check that the active mode shows 8K at 60 Hz with HDR on; the cable supports DSC and 40 Gbps, enabling that mode when both ends are DisplayPort 2.1.
