Q1: Why am I noticing fan activity when FusionDock Ultra is under heavy load?

1. The FusionDock Ultra features a high-performance dual-chip design to support quad-display output and 26 ports. To ensure stable performance during heavy use, it includes active cooling fans that help prevent issues

such as screen flickering, performance throttling, or system instability under heavy load.

2. The built-in NTC temperature sensor adjusts fan speed based on system load. During light use, the fan runs at a lower speed to minimize noise. When additional cooling is needed, the fan speeds up, with noise levels

staying below 50 dB when measured at close range (about 1 cm from the dock) in a controlled silent room,

similar to a library environment.

3. If you notice unusual noises such as high-pitched whining or squeaking, unplug the docking station’s power adapter and wait 60 seconds. After plugging the adapter back in, unplug and reconnect the dual USB-C cable.

If the noise continues, please contact iVANKY support for further assistance.

3. Use the included dual USB-C cable to connect the upstream ports (marked with the laptop icon) on the back of the dock to your laptop. If your MacBook asks for permission to connect the dock, click “Allow”.

4. Try connecting the dock to another MacBook to rule out port issues.

5. If the issue persists, contact iVANKY customer support.

Q4: What to do if the Ethernet port on the docking station does not reach the claimed 10Gbps speed?

1. Use a Cat6a or Cat7/Cat8 Ethernet cable (no longer than 328 feet) to support 10Gbps speed. Older cables, such as Cat5 or Cat6, may reduce performance.

2. On macOS, go to System Settings > Network, select your wired connection, click Details, then go to the Hardware tab. Set Configure to Manually, Speed to 10000Base-T, and Duplex to full-duplex. Click OK to save the settings.

3. Connect the docking station to another laptop to check if the issue persists.

4. Disconnect the dock and all devices. Wait at least 5 minutes, restart your laptop, then reconnect the dock and test again.

5. If the issue persists, contact iVANKY customer support.

Q5: Why is the display unable to reach the resolution of 5K or 6K?

1. Check if the display supports resolutions above 4K.

2. Only USB-C (80/120Gbps) Downstream Ports and DP Port support 5K or higher resolution.

3. If you are using a video cable adapter, please make sure that your adapter supports 5K or 6K resolution.

Q6: Why don't the colors on my external displays look right?

1. Select the display profile that matches your external monitor. On your Mac, go to “Apple menu” > System Settings, then click “Displays” in the sidebar (you may need to scroll down).

2. In the “Color profile” section, click the drop-down menu and select the profile that best suits your monitor.
