SMUGDESK DisplayPort 2.1 cable 6.6FT 40Gbps

This VESA certified DisplayPort 2.1 cable delivers 40Gbps bandwidth over a 6.6FT length. It supports 8K at 60Hz, 4K at 144Hz, and 2K at 240Hz with HDR10. The cable suits gamers and creators connecting high-refresh monitors to modern graphics cards. Backward compatibility covers DisplayPort 2.0, 1.4, 1.3, 1.2, 1.1 and 1.0 devices.

Bandwidth and resolution limits at 40Gbps

The 40Gbps link enables 8K at 60Hz, 4K at 120Hz or 144Hz, and 2K at 165Hz or 240Hz using DSC 1.2a compression. HBR10 signalling, HDCP 2.2, FEC forward error correction and 32 audio channels are supported. Multi-stream transport allows daisy-chaining compatible displays. Longer runs or higher uncompressed resolutions would exceed this cable’s rated throughput.

Upgrade from older DisplayPort cables

This cable replaces legacy DisplayPort 1.2 or 1.4 leads that cap at lower bandwidths and refresh rates. The jump is worth it when moving to an 8K panel, a 4K 144Hz gaming monitor, or a 2K 240Hz esports display. It also adds HDR10, HDCP 2.2 and MST support missing from earlier cables. Buyers staying at 4K 60Hz or below will not use the extra headroom.

Questions about this item

Should I pick the 6.6FT length for my desk setup?

The cable is 6.6FT long, which suits most desktop-to-monitor distances while keeping the full 40Gbps bandwidth for 8K@60Hz or 4K@144Hz.

Will 40Gbps actually deliver 4K@144Hz on my monitor?

Yes, the 40Gbps link supports 4K@144Hz with DSC 1.2a compression, plus HDR10 and 32 audio channels, provided your graphics card and monitor both implement DisplayPort 2.1.

Does the DisplayPort 2.1 interface limit me to 40Gbps in practice?

The cable is rated for 40Gbps (HBR10) and remains backwards compatible with DisplayPort 2.0, 1.4, 1.3, 1.2 and earlier, so it will run at the highest speed both ends support.
