4. Operating Instructions
Once set up, the ALOGIC DV3 Mini Dock operates seamlessly with your connected devices.
4.1 Display Configuration
- Extend or Mirror Displays: After connecting external monitors, you can configure your display settings through your operating system.
- Windows: Right-click on the desktop, select "Display settings," and choose "Extend these displays" or "Duplicate these displays."
- macOS: Go to System Settings > Displays. You can arrange displays, set resolutions, and choose between "Extend" or "Mirror" modes.
- Resolution Support: The HDMI port supports resolutions up to 4K (3840x2160), while the VGA port supports up to Full HD (1920x1080). When using both simultaneously, the resolution may be limited by the capabilities of the connected displays and the host device.

- Gigabit Ethernet: Once an Ethernet cable is connected, your computer should automatically detect the wired network connection. This provides a more stable and faster internet connection compared to Wi-Fi.
4.4 Power Delivery
- USB-C PD Port: If a USB-C power adapter is connected to the dock's PD port, it will pass power through to your host laptop, charging it while you work. This eliminates the need for a separate laptop power cable.
