3. Instructions de configuration
Follow these steps to set up your i-tec USB C Dual Monitor Docking Station.
- Branchement de l'alimentation (facultatif mais recommandé) : 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.
- Se connecter au périphérique hôte : Use the integrated USB-C cable to connect the docking station to your laptop's USB-C or Thunderbolt 3 port.
- Connecter des moniteurs externes : 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.
- Connectez les périphériques : 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.

4.1. Bouton d'alimentation
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. Configuration de l'affichage
After connecting external monitors, configure your display settings through your operating system. Options typically include:
- Étendre: Each monitor displays a separate desktop, expanding your workspace.
- Mirror/Duplicate: Tous les écrans affichent le même contenu.
- Deuxième écran uniquement : 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. Compatibilité
The docking station is compatible with devices featuring a USB-C or Thunderbolt 3 port that supports video output (DisplayPort Alternate Mode).
5.1. Systèmes d'exploitation pris en charge
- Windows 10 et versions ultérieures

5.2. Display Output Limitations

Note for macOS Users: 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. Entretien
To ensure optimal performance and longevity of your docking station, follow these maintenance guidelines:
- Conservez l'appareil dans un endroit sec, à l'abri de la lumière directe du soleil et des températures extrêmes.
- Évitez d'exposer l'appareil à l'eau ou à d'autres liquides.
- Nettoyez l'appareil avec un chiffon doux et sec. N'utilisez pas de produits chimiques agressifs ni de nettoyants abrasifs.
- Assurez une ventilation adéquate autour de la station d'accueil pour éviter toute surchauffe.
7. Dépannage
Si vous rencontrez des problèmes avec votre station d'accueil, consultez les problèmes et solutions courants suivants :
