STARTECH DP21-6F-DP40-CABLE displayport cable 6ft

SKU CH-7ZNX-XVEKH MPN DP21-6F-DP40-CABLE

A VESA-certified DisplayPort 2.1 cable delivering 40 Gbps bandwidth for 8K 60 Hz with DSC, 4K 144 Hz and 1440p 240 Hz, plus 32-channel audio and MST daisy-chaining

  • VESA certified DP 2.1 cable ensures reliable 40 Gbps signal integrity
  • UHBR10 bandwidth delivers 8K 60 Hz with DSC 1.2a compression
  • Backward compatible with DP 2.0, 1.4 and 1.2 devices
  • Nickel-plated connectors rated beyond 10000 insertions with latching lock
  • Flexible 6.5 mm TPE jacket routes easily through tight spaces

What this cable connects

This six-foot DisplayPort 2.1 cable links a UHBR10-capable graphics card or docking station to an 8K monitor. It carries 40 Gbps of bandwidth with DSC 1.2a compression, 32-channel audio, HDR and HDCP 2.2. The latching connectors and flexible TPE jacket suit tight routing behind desks or in rack cabinets.

The spec that decides fit

VESA certification at the DP40 tier guarantees 40 Gbps throughput for 8K at 60 Hz, 4K at 144 Hz or 1440p at 240 Hz. Backward compatibility with DisplayPort 2.0, 1.4 and 1.2 means the same cable works on older ports, but only a UHBR10 source unlocks the full 40 Gbps link rate.

Behaviour under sustained load

Nickel-plated contacts rated beyond 10,000 insertions and an aluminium-mylar shield maintain signal integrity during long sessions. The halogen-free, RoHS-compliant jacket and strain reliefs resist heat build-up, so the 40 Gbps link stays stable without drop-outs or sparkle artefacts over extended use.

Questions about this item

What does the 40 Gbps DP40 rating actually deliver on my monitor?

The DP40 rating provides 40 Gbps bandwidth, enabling 8K at 60 Hz with DSC 1.2a, 4K at 144 Hz, or 1440p at 240 Hz, plus 32-channel audio and HDR support.

How does the DisplayPort 2.1 interface with UHBR10 limit real-world performance?

UHBR10 caps the link at 40 Gbps, so the cable handles 8K 60 Hz with DSC, 4K 144 Hz, and 1440p 240 Hz; it is backward compatible with DP 2.0, 1.4, and 1.2 devices.

Will the 6.5 mm diameter and latching connectors fit my tight GPU backplate?

The cable has a 6.5 mm outer diameter with a flexible TPE jacket and strain reliefs; latching DisplayPort connectors secure the link and are rated beyond 10,000 insertions.
