3 m DisplayPort 2.1 cable for 8K and high-refresh 4K

This three-metre cable carries a VESA-certified DisplayPort 2.1 signal at 40 Gbps. It supports 8K resolution at 60 Hz and 4K resolution at 144 Hz with DSC 1.2a compression. The link is rated for HDR and HDCP 2.2 content protection. It is built for users who need a single, long-run connection between a modern GPU and a high-performance display.

Male-to-male layout fits GPU-to-monitor runs

Both ends carry a standard full-size DisplayPort connector, so the cable plugs directly into a graphics card output and a monitor input. The three-metre length gives routing flexibility across a desk or through cable management channels. No external power or active electronics are required, keeping the signal path simple and the installation clean.

VESA certification and two-year warranty back

The DP40 badge confirms the cable meets VESA’s 40 Gbps compliance programme for DisplayPort 2.1. The manufacturer covers the cable with a two-year warranty, replacing units that fail under normal use. No additional software or driver bundles are included; the cable is a passive interconnect that works immediately on any compatible host and display.

Questions about this item

How far can the 3 m length carry 8K 60 Hz without signal loss?

The cable is VESA certified DP40 for 40 Gbps bandwidth, supporting 8K 60 Hz and 4K 144 Hz over the full 3 m run with DSC 1.2a compression.

Does the cable or its connectors get warm during continuous 8K 60 Hz streaming?

Passive copper construction with DP 2.1 UHBR10 signalling runs within spec at 40 Gbps, so connector housings stay at ambient temperature during all-day use.

Which ports must my monitor and GPU provide for this cable to work?

Both devices need a standard DisplayPort 2.1 receptacle; the cable carries male-to-male DP connectors with HDCP 2.2 and HDR support built in.
