Description

StarTech DP21-3M-DP40-CABLE DisplayPort 2.1 Cable

Overview

This 3-meter (9.8 ft) StarTech DP21-3M-DP40-CABLE is a VESA Certified DP40 cable engineered for DisplayPort 2.1 connectivity. It supports UHBR10 data rates, enabling resolutions up to 8K at 60Hz with DSC, or 4K at 144Hz. The cable features a durable black TPE jacket and robust aluminum-mylar foil with braid shielding to minimize electromagnetic interference, ensuring signal integrity for demanding video applications in professional environments. The 30 AWG wire gauge and nickel-plated connectors further contribute to reliable data transmission. This cable is ideal for connecting high-resolution displays, workstations, or video walls where maximum bandwidth and signal stability are critical.

Compatibility

This cable is compatible with any device featuring a standard DisplayPort output and input, including graphics cards, monitors, and docking stations that support DisplayPort 2.1 standards. It is backward compatible with previous DisplayPort versions. Specific resolutions supported include 8K 60Hz with Display Stream Compression (DSC), 4K 144Hz, and 1440p 240Hz. It also supports 32-channel audio passthrough.

Installation Notes

The cable operates within an ambient temperature range of 0°C to 45°C (32°F to 113°F). Storage temperature should be between -20°C to 70°C (-4°F to 158°F). The operating humidity range is 10% to 85% RH.
