Who is it suitable for and how to use it?

This 10-in-1 USB-C hub is perfect for programmers, video editors, and office workers who need to use multiple monitors, a network cable, and external storage devices simultaneously.

Buyer questions

Question: What should I do if two monitors cannot simultaneously reach 4K@60Hz?
This may be due to bandwidth limitations of the laptop. Check if your computer supports DP 1.4, reduce the resolution or refresh rate, or try a different high-quality HDMI cable.

Question: Why can't the monitor reach 8K@30Hz resolution?
Make sure the monitor is connected only to the HDMI2 port. Also, check if your computer supports DP1.4 and DSC compression — without DSC, only 4K@60Hz is achievable.

Question: Why do both screens show the same image when connected to a Mac?
macOS does not limit itself to just one extended display — the other screen may only mirror the first screen's image because Macs do not support multiple independent display stream (MST) technology.

This 10-in-1 USB-C hub combines video, network, charging, and data transfer functions in a durable aluminum housing. It is suitable for office work, creative tasks, and travel with your MacBook or other USB-C devices.
