Description

StarTech DKT31CDHPD3 USB-C Multiport Adapter

Overview

The StarTech DKT31CDHPD3 is a versatile USB-C multiport adapter designed to expand the connectivity of modern laptops, particularly those used in professional environments where single-monitor 4K 60Hz HDR10 output is critical. It consolidates multiple peripherals into a single connection, reducing desk clutter and enabling a more efficient workstation setup. This adapter is ideal for users requiring high-resolution external displays, fast data transfer, and reliable network connectivity without sacrificing laptop charging capabilities. The 12.6-inch (32 cm) integrated host cable ensures it can reach comfortably from a laptop's USB-C port to a desktop workstation.

Compatibility

This adapter requires a USB-C port that supports USB Power Delivery 3.0 and DisplayPort Alternate Mode (DP Alt Mode). It is compatible with Thunderbolt 3 and Thunderbolt 4 ports, as well as standard USB 3.1 Gen 1/Gen 2 and USB 4 ports that meet these requirements. It supports Windows 10/11, macOS 10.15+, and Linux distributions. For 4K 60Hz output, the host system's USB-C port must support DisplayPort 1.4 or higher. HDR10 requires a host system and display that also support HDR10.

Installation Notes

The adapter consumes up to 15W of power itself, which is drawn from the host device or the connected Power Delivery charger. For full 100W PD input, a charger capable of at least 100W (including the adapter's 15W consumption) is required to deliver up to 85W to the connected laptop. The operating temperature range is 0°C to 50°C (32°F to 122°F), and storage temperature is -20°C to 55°C (-4°F to 131°F). Humidity should be kept between 0% and 85% non-condensing.
