1. What should I do if there is no image output from the HDMI port?

• Ensure your laptop's USB-C port supports video output (DisplayPort Alt Mode). Not all USB-C ports support video.
• Check the HDMI cable: ensure it meets standard specifications, is not overly long, and is firmly connected at both ends.
• Confirm your laptop's display resolution settings. The monitor's supported resolution may be lower than the dock's maximum output.
• Verify the monitor is set to the correct input source (e.g., HDMI 1, HDMI 2). Some monitors do not auto-switch.
• Try restarting your laptop or reconnecting the docking station.
• If possible, test with a different monitor or laptop to rule out device compatibility issues.

2. Why can't I see any display after connecting two HDMI monitors?

• Check if your laptop's graphics card supports dual external displays. Some devices only support extending to one monitor. Confirm this in your laptop's specifications or by contacting the manufacturer.
• Review your power settings. In Windows, go to Power Options and select "High performance" to ensure full hardware output is enabled.
• Go to your Display Settings (Windows: Settings > System > Display) and confirm displays are set to "Extend these displays" instead of "Show only on 1" or "Show only on 2".

3. Why can't I reach the desired resolution after connecting the docking station?

Several factors can affect resolution:

• USB-C bandwidth limitations: Your laptop's USB-C port may not support enough bandwidth for high-resolution or multi-display output.
• Laptop or graphics card limitations: Some laptops, especially those with integrated graphics, may not support higher resolutions or multiple high-res displays simultaneously.
• Monitor limitations: Your monitor may not support the maximum resolution set by the docking station.
• Cable quality: Low-quality or overly long HDMI/Display cables can reduce signal quality, leading to lower resolution or flickering.
• Incorrect display settings: Check your system's display settings and manually set the desired resolution (Windows: Settings > Display, macOS: System Settings > Displays).

4. Why can't my MacBook achieve multi-display extended mode (ABC) through the Acer docking station?

macOS system-level restrictions prevent multi-display extended mode via most docking stations. Connected external monitors will mirror the primary display instead of extending it. macOS typically displays as AAA or ABB in this scenario.

5. How do I set Mirror or Extended Mode on Windows and Mac laptops?

For Windows:

Press "Windows + P". A side menu will appear with options:

• Duplicate: Mirror the main screen to the second monitor.
• Extend: Extend your desktop across multiple screens.
• Second screen only: Only display on the external monitor.

Alternatively, navigate to: Settings > System > Display, scroll to the Multiple displays section, and choose your preferred display mode.

For macOS:

Click the Apple menu > System Settings (or System Preferences) > Displays.

• To mirror displays, enable the "Mirror Displays" checkbox.
• To extend displays, uncheck "Mirror Displays". macOS will treat each monitor as a separate screen.

Note: On macOS, you can drag and arrange displays manually in the display settings to control their position.

1. Why is my laptop not charging via the PD port?

• Ensure a proper external power adapter is connected to the PD (Power Delivery) port on the docking station before connecting the laptop.
• Confirm your laptop's USB-C port supports charging (Power Delivery). Not all USB-C ports support power input.
• Try disconnecting and reconnecting the docking station to refresh the connection and power negotiation.

Note: For optimal performance, use a USB-C charger and charging cable that supports the PD protocol and provides power higher than the device's minimum charging requirement of 10W.

2. Why does my laptop display a "slow charging" message?

Common reasons include:

• Use a higher-wattage power adapter: The docking station consumes 10W of power. Use a charger and cable with power output higher than your device's requirements (e.g., 70W or higher for a 60W device) to prevent "slow charging" warnings.
• Update drivers and firmware: Ensure your system has the latest firmware and drivers, which often optimize power management and USB-C charging.
• Check for a dedicated DC charging port: Some laptops are designed for DC barrel port charging and may show "slow charging" via USB-C PD. This is normal behavior; use the original DC charger if possible.

3. Can USB-A or USB-C data ports be used for charging?

USB-A and USB-C data ports are primarily for data transfer, not charging. Their total power output is 5V 900mA, which is insufficient for most devices. Using them for power supply may cause other interface functions to malfunction.

4. Can the second USB-C port charge my laptop?

The docking station has three USB-C ports. Only the PD USB-C port supports fast charging. The other two USB-C ports are for data transfer only and have very low power output.

1. Why does the "USB device might need more power" message appear?

This message typically occurs due to insufficient power supply to the docking station when multiple high-power devices (external monitors, USB drives, peripherals) are connected simultaneously.

Reasons:

• Power distribution limit: USB-C ports have limited output. Connecting multiple displays and USB devices may exceed the dock's capacity.
• No external power adapter connected: If not connected to a dedicated PD charger, the dock draws power from the laptop's USB-C port, which might be insufficient.
• Low-wattage charger used: A 45W or lower charger may trigger this warning when more power is needed for connected peripherals.

Recommended Solution:

• Use a charger and charging cable with power output higher than your device's requirements.
• Connect power to the docking station before connecting external displays and USB devices.
• If possible, reduce the number of connected high-power peripherals or switch to lower-resolution settings when using limited power.

Note: To ensure stable video and data transmission, connect the charger before HDMI or USB devices, and keep it connected until use is complete. Unplugging power during use may cause screen interruption or data loss.

2. Why is there lag or delay with wireless peripherals?

Wireless lag or delay can be caused by USB 3.0 electromagnetic interference, which disrupts 2.4GHz wireless signals used by many keyboards and mice. This is a known issue.

Main reasons:

• USB 3.0 Interference: USB 3.0 ports emit electromagnetic noise on the 2.4GHz frequency, potentially causing signal dropouts or lag if the receiver is too close.
• Receiver placement: Plugging the wireless dongle directly into the docking station near USB 3.0 ports can increase interference.
• Insufficient power supply: Low power delivery to the docking station can impact overall USB performance and peripheral responsiveness.

Solutions:

• Use a USB extension cable to position the wireless receiver away from the docking station.
• Plug the receiver into a USB-A port directly on your laptop if available.
• Ensure the docking station is powered by a 65W+ PD charger for stable USB performance.
• For critical tasks, consider using a Bluetooth mouse/keyboard or a wired connection to avoid wireless interference.

1. How to use the one-touch lock screen feature?

• Windows: Single-click the lock button to instantly lock your screen.
• macOS: Press and hold for 3 seconds to activate the screen lock.

Note: This function locks the screen for privacy. To unlock, manually enter your password or use biometric authentication (e.g., fingerprint/face ID).

2. Is it normal for the docking station to become warm?

Yes, it is normal for the docking station to feel warm during operation, especially models with a full aluminum alloy casing designed for heat dissipation.

Reasons for heat:

• Multiple devices connected: Connecting displays, USB drives, SD cards, and PD charging handles high data and power loads, generating heat.
• Aluminum alloy housing: The aluminum casing conducts and releases internal heat, indicating proper dissipation, not a malfunction.
• PD charging adds thermal load: Using the PD port for laptop charging involves significant power transfer, contributing to surface temperature rise.

Prolonged Usage Tips:

• Ensure the dock is placed on a flat, hard surface with good airflow for better heat dissipation.
• Avoid covering it or using it on soft materials like fabric.
• If the dock becomes abnormally hot or malfunctions, unplug it and allow it to cool before reconnecting.
• Mild to moderate warmth is expected and safe during normal use. The aluminum shell helps maintain performance by dispersing heat effectively.
