3. Einrichtungsanweisungen
Follow these steps to set up your i-tec USB C Dual Monitor Docking Station.
- Stromanschluss (optional, aber empfohlen): Connect your original USB-C charger (up to 100W) to the USB-C Power Delivery (USB-C PD) port on the docking station. This provides power to the docking station and charges your connected laptop. If not using a power adapter, some USB 3.0 and USB-C data ports may not function optimally with high-power devices.
- Verbindung zum Hostgerät herstellen: Use the integrated USB-C cable to connect the docking station to your laptop's USB-C or Thunderbolt 3 port.
- Externe Monitore anschließen: Connect your monitors to the two DisplayPort outputs on the docking station.
- Windows/Ubuntu: Supports up to two 4K/60Hz external monitors with extended or mirrored display modes.
- macOS: Supports up to one 4K/60Hz external monitor. When connecting two monitors, both will display the same image due to macOS not supporting Multi-Stream Transport (MST) technology.
- Peripheriegeräte anschließen: Connect your USB devices (keyboard, mouse, external drives) to the available USB 3.0 and USB 2.0 ports. Connect your Ethernet cable to the Gigabit Ethernet (LAN) port for a wired network connection. Connect headphones or a microphone to the combined audio/mic jack.

4. Bedienungsanleitung
4.1. Einschalttaste
The docking station features a power button on the top panel. Press and hold the power button for approximately 2 seconds to turn the unit on or off. This delay prevents accidental shutdowns.
4.2. Anzeigekonfiguration
After connecting external monitors, configure your display settings through your operating system. Options typically include:
- Verlängern: Each monitor displays a separate desktop, expanding your workspace.
- Mirror/Duplicate: Alle Monitore zeigen den gleichen Inhalt an.
- Nur zweiter Bildschirm: Only the external monitor(s) display content, with the laptop screen turned off.
4.3. Charging Functionality
When a compatible USB-C charger is connected to the docking station's USB-C PD port, the docking station will pass through up to 100W of power to charge your connected laptop. Additionally, the USB-C 3.1 Gen 2 port on the front panel supports fast charging for smartphones and tablets.
5. Kompatibilität
The docking station is compatible with devices featuring a USB-C or Thunderbolt 3 port that supports video output (DisplayPort Alternate Mode).
5.1. Unterstützte Betriebssysteme
- Windows 10 und höher
- macOS X and later
- Android
- ChromeOS
- Linux
5.2. Display Output Limitations

Hinweis für macOS-Benutzer: macOS does not support Multi-Stream Transport (MST) technology. This means that when two monitors are connected to the docking station on a macOS device, both monitors will display the same image (mirroring), not an extended desktop across two separate displays. For extended desktop functionality on macOS, only one external monitor can be used with the docking station.
5.3. VESA Mounting Support
The docking station features VESA support, allowing for vertical installation behind a VESA compatible monitor. This helps in creating a clean and organized workspace.

6. Wartung
To ensure optimal performance and longevity of your docking station, follow these maintenance guidelines:
- Bewahren Sie das Gerät in einer trockenen Umgebung, fern von direkter Sonneneinstrahlung und extremen Temperaturen auf.
- Vermeiden Sie es, das Gerät Wasser oder anderen Flüssigkeiten auszusetzen.
- Reinigen Sie das Gerät mit einem weichen, trockenen Tuch. Verwenden Sie keine scharfen Chemikalien oder Scheuermittel.
- Um eine Überhitzung zu vermeiden, muss für ausreichende Belüftung rund um die Dockingstation gesorgt werden.
7. Fehlerbehebung
Sollten Sie Probleme mit Ihrer Dockingstation haben, beachten Sie bitte die folgenden häufig auftretenden Probleme und Lösungen:
- Keine Anzeigeausgabe:
- Stellen Sie sicher, dass der USB-C-Anschluss Ihres Laptops den DisplayPort-Alternativmodus unterstützt.
- Verify that the DisplayPort cables are securely connected to both the docking station and the monitors.
- Check your operating system's display settings to ensure external monitors are detected and configured correctly.
- If using macOS, remember that only one external monitor will extend the desktop; two monitors will mirror.
- USB-Geräte funktionieren nicht:
- Ensure the docking station is connected to a power adapter, especially for high-power USB devices like external SSDs. Without a power adapter, USB 3.0 and USB-C data ports may have limited functionality.
- Versuchen Sie, das USB-Gerät an einen anderen Anschluss der Dockingstation anzuschließen.
- Ensure device drivers are up to date on your host system.
- Keine Netzwerkverbindung:
- Vergewissern Sie sich, dass das Ethernet-Kabel sowohl an die Dockingstation als auch an Ihren Router/Ihr Modem fest angeschlossen ist.
- Überprüfen Sie die Netzwerkeinstellungen auf Ihrem Hostgerät.
- Laptop lädt nicht:
- Ensure your original USB-C charger is connected to the USB-C PD port on the docking station.
- Prüfen Sie, ob der USB-C-Anschluss Ihres Laptops Power Delivery unterstützt.
