Important Notes

• Only 2 video streams can be active simultaneously
• macOS may support mirrored displays instead of extended mode
• Maximum resolution depends on host and display capabilities
• Dock must be powered ON before use

LED Indicators

• Orange → Power ON
• Blue → Connected to host
• Ethernet (RJ45):
  • Orange = Network connected
  • Green blinking = Data activity

Display Streams & Resolution Explained

What is a “Stream”?

A video stream is one independent video signal coming from your laptop or PC to the dock.

• Each stream drives a display signal path
• The dock provides multiple display outputs (DisplayPort + HDMI™ 1 + HDMI™ 2 + Thunderbolt™ video)
• There is a limit to how many streams can be processed

Important:
The dock supports a maximum of 2 video streams simultaneously

Physical Stream Mapping on the Dock

Understanding the port layout helps explain display behavior:

Stream 1 (Front Panel)

• Thunderbolt™ 4 downstream port (front side of dock)

Used for:

• Thunderbolt™ monitors
• USB-C display adapters
• Daisy-chained devices

Stream 2 (Rear Panel – Shared Group)

• DisplayPort (rear panel)
• HDMI™ 1 (next to DisplayPort)

Notes:

• These ports share the same stream and bandwidth
• May display mirrored output, especially on macOS

Stream 3 (Rear Panel – Separate Path)

• HDMI™ 2 (next to USB 2.0 ports)

Notes:

• Separate internal path
• Still counts toward the total 2-stream limit

What This Means in Practice

Single Display

• Any port can be used
• Uses 1 stream
• Supports:
  • Up to 8K @ 30Hz
  • or high-refresh 4K

Dual Displays (Recommended)

Use two different stream groups:

Recommended configurations:

• DisplayPort (rear) + HDMI™ 2 (rear)
• HDMI™ 1 (rear) + HDMI™ 2 (rear)
• Thunderbolt™ (front) + HDMI™ 2 (rear)

Result:

• Up to 2 × 4K @ 60Hz

DisplayPort + HDMI™ 1

• Both ports are part of Stream 2 (shared)
• Result:
  • Mirrored display in many cases
  • Not independent outputs (especially on macOS)

Triple Displays (Windows only)

• Uses 2 streams with internal splitting (MST/compression)

Example configuration:

• Thunderbolt™ (front) + DisplayPort + HDMI™ 2

Result:

• Up to 3 × 4K @ 60Hz (extended on Windows)

Note:

• Still only 2 actual streams
• Third display shares available bandwidth

Mac vs Windows Behavior

Windows

• Supports MST (Multi-Stream Transport)
• Allows:
  • Multiple extended displays
  • Independent outputs on all ports

macOS

• Does not support MST
• Result:
  • DisplayPort + HDMI™ 1 may mirror
  • Thunderbolt™ (front) or HDMI™ 2 used for second display

Bandwidth Sharing Explained

Streams act as data pipelines:

• Total available bandwidth: 40Gbps (Thunderbolt™ 4)
• Shared between:
  • Displays
  • USB devices
  • Network

More displays reduce the available bandwidth per display.

Simple Setup Guide

Goal	Recommended Ports
1 display	Any port
2 displays (best)	DP (rear) + HDMI™ 2 (rear)
2 displays (alternative)	TB (front) + HDMI™ 2 (rear)
3 displays (Windows)	TB (front) + DP + HDMI™ 2
Mac dual display	TB (front) + HDMI™ 2

Key Takeaways

• Maximum 2 independent video streams
• Front Thunderbolt™ port uses its own stream
• DisplayPort + HDMI™ 1 share one stream
• HDMI™ 2 uses a separate path
• Windows supports full multi-display expansion
• macOS may mirror some outputs
• Resolution depends on bandwidth and host capability
