Black DisplayPort 2.1 cable with straight connectors, 6.6 ft long

SMUGDESK

SMUGDESK DisplayPort 2.1 cable 6.6 ft 40 Gbps

SKU CH-YF1H-Z8S3Q

A 6.6 ft DisplayPort 2.1 cable delivers 40 Gbps bandwidth for 8K at 60 Hz, 4K at 144 Hz, and 2K at 240 Hz with G-Sync and HDR support

  • 40 Gbps bandwidth drives 8K at 60 Hz
  • 4K at 144 Hz and 2K at 240 Hz for smooth gaming
  • Triple shielding with 28 AWG oxygen-free copper keeps signal clean
  • VESA certified DisplayPort 2.1 with HBR10 and DSC support
  • Backwards compatible to DP 1.1 and works with G-Sync and FreeSync

Cable purpose and audience

This DisplayPort 2.1 cable carries 40 Gbps bandwidth over a 6.6 ft run. It suits PC builders and gamers who need 8K at 60 Hz or 4K at 144 Hz from a single link. The VESA certified construction works with DP 2.0, 1.4, 1.2 and older revisions. It is not for installers who require plenum-rated jackets or lengths beyond 6.6 ft.

Sustained signal behaviour

Triple shielding and 28 AWG oxygen-free copper keep the 40 Gbps stream stable during long gaming sessions. The link supports DSC, Forward Error Correction and HDR metadata transport without drop-outs. Audio passes through uncompressed at 7.1 or 5.1 channels. Buyers who need lossless 16K at 60 Hz uncompressed should note the cable only reaches 16K at 30 Hz with DSC.

Build and connector implications

Each end carries a standard full-size DisplayPort plug with latching release. The 6.6 ft length reaches most desk-to-monitor routes without excess slack. Backwards compatibility lets the same cable serve a GTX 980 today and a DP 2.1 monitor tomorrow. Users who need Mini DisplayPort or USB-C Alternate Mode must use a separate adapter.

Questions about this item

How hot does the 28 AWG oxygen-free copper conductor get during extended 8K@60Hz sessions?

The cable uses 28 AWG oxygen-free copper and triple shielding to maintain signal integrity at 40 Gbps; it does not generate noticeable heat during normal operation.

What DisplayPort version must my graphics card and monitor support to use this cable at 40 Gbps?

Both devices need DisplayPort 2.1 ports to reach the full 40 Gbps HBR10 bandwidth; the cable is backwards compatible with DP 2.0, 1.4, 1.2 and 1.1 at lower speeds.

Will this cable work with my older GTX 980 or Radeon R9 290 at 4K@144Hz?

The GTX 980 and Radeon R9 290 support up to DisplayPort 1.4, so they can run 4K@120Hz or 4K@144Hz with DSC; the cable will carry those signals without issue.
