StarTech.com 3ft DisplayPort 2.1 Cable DP80 – UHBR20, HDR, DSC, 16K/8K 60Hz

Overview

The StarTech.com 3ft DisplayPort 2.1 cable delivers high-bandwidth performance for demanding displays and workstations. With DP80 (80 Gbps) bandwidth, it supports ultra-high resolutions and modern features such as HDR and DSC, enabling smooth visuals and rich audio at multiple refresh rates. This is a VESA-certified DP 2.1 cable that remains backward compatible with DP 2.0, 1.4, and 1.2 devices, offering flexible use across a mixed setup.

Designed for discerning creators, developers, and AV professionals, the cable can help you pair a capable Graphics Processing Unit with a high-end monitor or MST hub. While results vary by system, users may experience extended color depth, crisp detail, and reliable multi-monitor configurations when paired with compatible hardware.

Key capabilities

• Ultra-high bandwidth up to 80 Gbps (UHBR20) supports up to 16K at 60 Hz with DSC and 32 audio channels.
• Full DP 2.1 compatibility with backward support for DP 2.0/1.4/1.2, ensuring broad interoperability.
• G-Sync and FreeSync VRR compatibility to help reduce stutter and tear on supported displays.
• Robust physical design: latching nickel-plated connectors for secure mating and durability beyond 10,000 insertions.
• Flexible TPE jacket with a shielded, low-EMI construction to help protect signal integrity in busy workspaces.

Real-world use cases

• High-end workstation setups linking 16K/8K capable displays for content creation or data visualization.
• Multi-monitor arrangements via MST hubs, enabling efficient daisy-chaining with reliable signal delivery.
• Professional AV and media production environments where secure connections and long-term reliability matter.
• Docking station configurations where a compact 3-foot cable keeps desks tidy while preserving video quality.

Durability and build quality

The cable sports a braided aluminum mylar shielding to minimize EMI and preserve audio/video clarity. The rugged, halogen-free TPE jacket is designed for frequent routing around corners and edges, while a precision lugging system and latching connectors help prevent accidental disconnections in busy setups. The connectors are rated for more than 10,000 insertions, supporting repeated use over time.

Compatibility and tips

Because this is a DP 2.1 cable, it is best paired with devices that support UHBR20 or higher features. It remains compatible with legacy DP versions, so you can use it in mixed environments with confidence. For optimal results, ensure both the source and display advertise DP 2.1 functionality and DSC with your chosen resolutions and refresh rates.
