Overview

The Cable Matters DisplayPort 2.1 Cable is a VESA DP80-certified cable that delivers the next generation of display connectivity. With an incredible 80 Gbps bandwidth, it supports resolutions such as 8K at 120Hz and 16K at 60Hz — far beyond what older DisplayPort 1.4 cables can handle. This cable is designed for enthusiasts and professionals who demand uncompromised video quality from their high-end monitors and VR headsets.

Key Features

  • DP80 certified (UHBR20) for 80 Gbps bandwidth, enabling ultra-high resolution and refresh rates
  • Supports 8K@120Hz, 16K@60Hz, and 4K@240Hz+ with Display Stream Compression (DSC)
  • Fully compliant with DisplayPort 2.1 specification and backward compatible with DP 1.4/1.2
  • Triple-shielded construction for minimal electromagnetic interference and signal integrity
  • Gold-plated connectors with latching mechanism for secure, corrosion-free connections
  • 1.8-meter (6-foot) length ideal for desktop setups, offering flexibility without excess clutter

Compatibility Guide

DisplayPort 2.1 is backward compatible, so this cable works with any DisplayPort device. However, to achieve full 80 Gbps bandwidth, both the source (GPU) and display (monitor) must support DisplayPort 2.1 UHBR20. As of May 2026, compatible GPUs include AMD Radeon RX 7000 series and later, and NVIDIA GeForce RTX 40 series and later. Compatible monitors are becoming more common, especially high-end models with 4K@240Hz or 8K resolution.

Ideal Use Cases

  • Pairing with top-tier GPUs (e.g., Radeon RX 7900 XTX, GeForce RTX 5090) and 8K monitors for peak visual fidelity
  • Competitive gamers who want 4K at 240Hz for ultra-smooth gameplay
  • VR enthusiasts using DisplayPort-based headsets for maximum resolution and frame rate
  • Creative professionals handling high-bit-depth video or color-critical work that demands flawless signal transmission

Usage Notes

The 6-foot length is suitable for most desktop configurations. For longer runs, consider active repeaters or optical cables. Avoid sharp bends or placing heavy objects on the cable to prevent damage. While the cable is well-shielded, keep it away from strong electromagnetic sources if possible.
