3. Beállítási utasítások
Follow these steps to set up your i-tec USB C Dual Monitor Docking Station.
- Tápellátás csatlakoztatása (opcionális, de ajánlott): 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.
- Csatlakozás a gazdagéphez: Use the integrated USB-C cable to connect the docking station to your laptop's USB-C or Thunderbolt 3 port.
- Külső monitorok csatlakoztatása: 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.
- Perifériák csatlakoztatása: 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. Használati útmutató
4.1. Bekapcsológomb
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. Kijelző konfigurációja
After connecting external monitors, configure your display settings through your operating system. Options typically include:
- Hosszabbítás: Each monitor displays a separate desktop, expanding your workspace.
- Mirror/Duplicate: All monitors display the same content.
- Csak a második képernyő: Only the external monitor(s) display content, with the laptop screen turned off.
4.3. Töltési funkció
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. Kompatibilitás
The docking station is compatible with devices featuring a USB-C or Thunderbolt 3 port that supports video output (DisplayPort Alternate Mode).
5.1. Támogatott operációs rendszerek
- Windows 10 és újabb
- macOS X and later
- Android
- ChromeOS
- Linux
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. Karbantartás
To ensure optimal performance and longevity of your docking station, follow these maintenance guidelines:
- A készüléket száraz helyen, közvetlen napfénytől és szélsőséges hőmérsékletektől távol tartandó.
- Ne tegye ki a készüléket víznek vagy más folyadéknak.
- A készüléket puha, száraz ruhával tisztítsa. Ne használjon erős vegyszereket vagy súrolószereket.
- A túlmelegedés elkerülése érdekében biztosítson megfelelő szellőzést a dokkolóállomás körül.
7. Hibaelhárítás
Ha problémákat tapasztal a dokkolóállomással, tekintse meg az alábbi gyakori problémákat és megoldásokat:
- Nincs kijelző kimenet:
- Győződjön meg arról, hogy a laptop USB-C portja támogatja a DisplayPort alternatív módot.
- 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 Devices Not Functioning:
- 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.
- Próbálja meg az USB-eszközt a dokkolóállomás egy másik portjához csatlakoztatni.
- Ensure device drivers are up to date on your host system.
- Nincs hálózati kapcsolat:
- Ellenőrizze, hogy az Ethernet-kábel megfelelően csatlakozik-e mind a dokkolóállomáshoz, mind a routerhez/modemhez.
- Ellenőrizd a hálózati beállításokat a gazdagépeden.
- A laptop nem töltődik:
- Ensure your original USB-C charger is connected to the USB-C PD port on the docking station.
- Ellenőrizd, hogy a laptopod USB-C portja támogatja-e a Power Delivery funkciót.
