7. FAQ

Q1: What is the difference between Thunderbolt 4 and Thunderbolt 5?

Thunderbolt 5 offers significantly higher bandwidth (up to 120Gbps) compared to Thunderbolt 4 (40Gbps), improved display capabilities (e.g., higher resolutions and refresh rates), and enhanced power delivery.

Q2: Can I use a standard USB-C cable with the Thunderbolt 5 ports?

While the Thunderbolt 5 ports are USB-C compatible, using a standard USB-C cable may limit performance. For full Thunderbolt 5 speeds and features, a certified Thunderbolt 5 cable is recommended. For PD charging, ensure the cable supports the required wattage (e.g., 140W).

Q3: Is the docking station compatible with my MacBook?

The docking station is compatible with MacBooks featuring Thunderbolt 3 or later ports and running macOS 15 or later. Compatibility with specific M-series chips (M1, M2, M3, M4) and their variants (Pro, Max, Standard) is detailed in Section 2.2.

Q4: Does the docking station support eGPUs on Mac?

External GPU (eGPU) support is dependent on Apple's macOS and hardware. While Thunderbolt 5 offers high bandwidth, eGPU functionality is not guaranteed and may be limited by Apple's software support for specific Mac models and chipsets.

Q5: My USB-C device is not charging or charging slowly. What should I do?

Ensure the USB-C cable used supports the required charging wattage (e.g., 100W or 140W for PD). Check the device's power requirements and the docking station's USB-C port specifications. Also, verify that the host laptop is connected via Thunderbolt 5 for maximum power delivery.

Q6: How do I connect multiple monitors? Can I use both HDMI and DP simultaneously?

The docking station supports multiple display outputs via Thunderbolt 5, Thunderbolt 4/USB 4, and USB-C DP Alt Mode ports. Refer to Section 3 for specific resolution and refresh rate capabilities when using single or multiple displays. Check the port specifications for simultaneous output support.

Q7: What is DSC?

DSC stands for Display Stream Compression. It is a visually lossless compression technology used to transmit high-resolution and high-refresh-rate video signals over limited bandwidth. It allows for higher resolutions and refresh rates, such as 8K, to be supported over Thunderbolt 5/4 and USB4 connections.

Q8: Does the docking station support HDR?

Yes, the docking station supports HDR (High Dynamic Range) when connected via Thunderbolt/DP interfaces, provided the connected display and content also support HDR. Specific resolutions like 8K/30Hz or 4K/60Hz may be required for optimal HDR performance.

Q9: What is EDID?

EDID (Extended Display Identification Data) is a data structure used to communicate information about a display's capabilities (like resolution, refresh rate, and color depth) to the source device (your computer). The docking station supports EDID, allowing it to correctly identify and configure connected monitors.

Q10: How do I troubleshoot PD charging issues?

Ensure you are using a USB-C cable rated for the required wattage (e.g., 5A for 100W/140W PD). Verify the power adapter is correctly connected. Check your OS power settings and ensure the host device's USB-C port supports PD charging. For Windows, check power settings; for macOS, resetting the SMC (System Management Controller) on Intel Macs or checking system information might help.

Q11: My device shows "Not Charging" or "Low Charging Power" when connected via USB-C. What's wrong?

This can occur if the connected device requires more power than the USB-C port can provide (e.g., 5V/3A = 15W). Some devices may require specific PD profiles (e.g., 9V/2.22A for 20W charging). Ensure the device's charging requirements are met by the port's output. Also, check for E-Marker chips in cables for higher power delivery.

Q12: How do I ensure I can achieve 140W PD charging?

To achieve 140W PD charging, you must use a USB-C cable specifically rated for 5A current and equipped with an E-Marker chip. Standard USB-C cables rated for 3A will not support 140W. Ensure the power adapter is the original 180W adapter and the host device supports receiving 140W PD.

Q13: What is the recommended operating temperature for the docking station?

The recommended operating temperature range for the docking station is 0°C to 40°C (32°F to 104°F).
