This User Manual covers setup, port reference, display configuration, and troubleshooting for the Satechi Thunderbolt 4 Multimedia Pro Dock (ST-DT4PMM-US / ST-DT4PMM-EU / ST-DT4PMM-UK). The Thunderbolt 4 Multimedia Pro Dock is a desktop docking station that expands a single Thunderbolt 4 or USB4 port into a comprehensive workstation hub — supporting multiple displays, high-speed data, USB peripherals, Ethernet, SD card readers, and up to 96W laptop charging.

Display Configuration

The Thunderbolt 4 Multimedia Pro Dock supports multiple external displays depending on the host computer's capabilities:

• Mac with Apple Silicon (M1/M2/M3/M4) — Supports up to 2 external displays via the dock (one via Thunderbolt 4 downstream, one via HDMI). Requires macOS Ventura or later with DisplayLink support for additional displays.
• Mac with Intel — Supports up to 2 external displays natively.
• Windows laptops (Thunderbolt 4) — Up to 2 external displays at 4K @ 60Hz.

For non-mirrored (extended) display setup on macOS: System Settings > Displays > Arrangement, then disable Mirror Displays.

Troubleshooting

• Dock not recognized — Ensure the power adapter is connected. Use the included Thunderbolt 4 cable and connect to the Thunderbolt 4 (⚡) port on your laptop. Try a different Thunderbolt 4 port.
• Display not detected — Connect display before powering on the dock. On macOS go to System Settings > Displays and click "Detect Displays." Ensure the display cable supports the target resolution.
• USB devices not working — Unplug and reconnect the device. Try a different USB port on the dock. Some USB devices require direct connection to the computer rather than a hub.
• Ethernet not detected — Check the Ethernet cable connection. On macOS, go to System Settings > Network and confirm the Ethernet interface is active. A 2.5GbE switch or router is required for 2.5Gbps speeds.
• Laptop charging slowly — Confirm the power adapter is connected to the dock. MacBook Pro models requiring more than 96W may charge slowly when the dock is also powering multiple peripherals.
