Q:Why is there no display when connecting to an HDMI monitor?
A: When connecting an HDMI monitor through a USB-C HUB, the USB-C port on the laptop must support audio and video output. Please ensure your laptop’s USB-C port supports this capability.
Q: The laptop's USB-C port supports audio and video output, so why is there no display when connecting to an
A: Please try disconnecting the HUB from the laptop, shutting down the laptop, and then pressing and holding the power button for 40 seconds to discharge any static electricity.
Q: How do I set the HDMI monitor to mirror or extend mode? Windows OS: You can press the Windows + P keys to select the display mode, or go to "System Settings" and find "Display Settings" to adjust the display mode.
macOS: Open "System Preferences," go to the "Displays" option, and from there, you can choose to set the display to mirror or extend mode.
Q: Why can't I set a higher resolution when connecting multiple HDMI monitors?
A: On Windows systems, when connecting multiple HDMI monitors, the maximum supported resolution is 1080P @60Hz. If only one HDMI monitor is connected, the resolution depends on the capabilities of both the laptop and the monitor, with a maximum of 4K @30Hz. On macOS, the maximum supported resolution
Q: Why can't a MacBook achieve triple-screen extended display when connected to multiple HDMI monitors?
A: macOS does not support MST (Multi-Stream Transport) technology. As a result, only mirroring (AAA) or duplicating the same extended display (ABB) is supported, and triple-screen extended mode is not supported.
Q: Does the HUB's HDMI port support other refresh rates?
A: The HDMI port supports up to 1080P at 60Hz and 4K at 30Hz. When connecting an HDMI monitor alone, the resolution displayed depends on the laptop's USB-C port and the resolution supported by the monitor (e.g., 2560x1440P @144Hz).
Q: Can a USB-C monitor be connected?
A: No, the HUB's USB-C PD port only supports connecting to a PD power adapter, and the USB-C data port only supports connecting storage devices for data transfer. To connect a monitor, please use the HDMI connection.
Q: My laptop doesn't have a USB-C port. Can I use a USB-A adapter?
A: No, using a USB-A adapter to connect the HUB will result in the HDMI and other ports being unable to output audio and video, causing the monitor and other devices to not function properly.
Q: Can I use a USB-C extension cable to connect the HUB?
A: Using a USB-C extension cable may weaken the signal, leading to some ports (such as HDMI) not displaying properly. It is not recommended to use a USB-C extension cable.
Q: Why is there no audio output when connecting a 3.5mm audio device?
A: Please confirm that your laptop's USB-C port supports audio and video output. The HUB's 3.5mm audio output follows the HDMI audio output. You need to switch the laptop's audio output settings to LCD or HDMI audio output. Some monitors may lack audio drivers, which can lead to the 3.5mm audio port not being recognized after connecting to an HDMI monitor. Please use a monitor with
HDMI audio capabilities for connection.

Q: Can the 3.5mm audio port be used for microphone input?
A: The 3.5mm audio port only supports audio output and does not support microphone input.
Q: How do I set a higher resolution and display mode when connecting a VGA monitor?
A: The VGA monitor supports up to 1080P at 60Hz.. When connecting multiple HDMI and VGA monitors, the maximum supported resolution is 1080P @60Hz. In extended mode settings, the VGA display follows the HDMI port next to it.
Q: Does it support connecting USB-C headphones?
A: The hub's USB-C port does not support audio output. Please use headphones connected via the USB-A or 3.5mm audio port.
Q: Why is the external hard drive not recognized or does the connection unexpectedly drop when transferring data?
A: The external hard drive may draw more power than the laptop’s USB-C port can supply, causing connection issues. It is recommended to use a PD power adapter connected to the HUB's USB-C PD port to ensure stable power supply and prevent connection interruptions.
Q: Why is there no charging indication when connecting the PD power adapter?
A: Please confirm whether your laptop's USB-C port supports PD charging functionality and check if the power adapter is connected properly. If the issue persists, it is recommended to try connecting a different PD power adapter to rule out compatibility issues with the PD charging protocol.
Q: Why does my laptop indicate slow charging when I connect the charger?
A: The HUB itself requires at least 13W of power to operate. It is recommended to use a higher wattage PD power adapter (preferably up to 100W). This ensures that there is sufficient power supplied to both the HUB and the laptop, avoiding slow charging issues.
Q: Does the HUB require driver installation before use?
A: The HUB is a plug-and-play external device and generally does not require manual driver installation.
Q: Why is the HUB intermittently disconnecting and not recognizing the Ethernet connection?
A: Please first check if the Ethernet cable is connected properly and verify that there are no IP address conflicts in the network settings. If the issue persists, it is recommended to download the latest network drivers from the official website to ensure the device operates correctly.
Q: Why can't the SD card be read?
A: Please check if the SD card is inserted correctly and ensure that the card's file format is compatible with the device.
