Troubleshooting
Q: Why cannot I cast a screen through the HDMI port?
A: Ensure your host device's USB-C port supports DisplayPort Alternate Mode (DP Alt Mode). Also, check the DP version of your device's USB-C port. For 4K@60Hz, a DP1.4 port is required. If it's DP1.2, the output will be 4K@30Hz.
Q: Why is the resolution not as advertised (e.g., 4K@60Hz)?
A: The maximum resolution and refresh rate depend on the capabilities of your host device's USB-C port. A DP1.4 compatible USB-C port is necessary for 4K@60Hz output. If your device has a DP1.2 USB-C port, the hub will output at 4K@30Hz.
Q: Why does the product get warm during operation?
A: It is normal for the hub to generate some heat during operation, especially when multiple ports are in use or when charging. The Baseus 7-in-1 Gen 2 USB C HUB incorporates Baseus BCT (Baseus Cooling Technology) temperature control technology for superb heat dissipation, ensuring safe operation without overheating.

Q: Can I connect my cell phone to a projector using this hub?
A: Yes, you can connect your cell phone or tablet to a projector via the HDMI port, provided your mobile device supports OTG (On-The-Go) expansion and DisplayPort Alternate Mode over USB-C.
