Does this switch support dual monitors simultaneously in 1-in-2-out mode?

No, the 8K USB-C Bi-Directional Switch cannot display video on two monitors simultaneously. In 1-in-2-out mode, the "SELECT" button toggles the video signal between Monitor A and Monitor B, meaning only one screen will be active at any given time.

Can I use this switch to charge my laptop while outputting video?

Yes, this switch supports up to 100W Power Delivery (PD) pass-through. If your Type-C monitor provides PD charging, the power will flow through the switch to keep your connected laptop charged while simultaneously transmitting video and data.

Why is my monitor flickering or showing no signal when connected?

Flickering or signal loss usually occurs if your Type-C cables exceed the strict 1.5-meter limit, or if your source device isn't providing enough power to the switch. To fix this, use shorter, certified 8K Type-C cables and plug a 5V power adapter into the dedicated "DC 5V" port on the switch.

Is this USB-C switch compatible with Thunderbolt 3 or Thunderbolt 4 ports?

Yes, this USB-C switch is backward compatible with Thunderbolt 3, Thunderbolt 4, and previous Type-C standards. However, it operates at USB-C 10Gbps data speeds and standard DisplayPort Alt Mode video protocols, not full Thunderbolt PCIe bandwidth.

Can I test this Type-C switch with my MacBook at your store?

Yes, you can bring your MacBook to Sun Cheong Computer Co. Ltd. (新昌電腦有限公司) in Sham Shui Po to test the switch. Our in-store technicians can help verify compatibility with your specific laptop and recommend the correct high-bandwidth cables for your setup.

Full Product Description

Seamless USB-C Switching for Modern Workspaces

The 8K USB-C Bi-Directional Switch lets you instantly toggle video, data, and power between two devices using a single physical button. Instead of constantly plugging and unplugging cables behind your desk, this hub allows you to share a single high-end Type-C monitor (and its connected peripherals) between your personal gaming PC and your work laptop with zero hassle.

True Bi-Directional 8K Video & 100W PD

This versatile Type-C Switcher operates in either 2-in-1-out or 1-in-2-out modes while supporting massive 100W Power Delivery. In 2-in-1-out mode, two computers can share one display; in 1-in-2-out mode, one computer can switch its output between two different monitors (note: displays cannot work simultaneously). It supports ultra-high resolutions up to 8K@60Hz, 4K@120Hz, and 1080P@240Hz, ensuring buttery-smooth visuals for both creative work and competitive gaming.

Pro Tip from Our Technicians

For flawless 8K@60Hz or 4K@120Hz transmission, our Sham Shui Po technical team strongly advises keeping your Type-C cables strictly under 1.5 meters on both ends of the switch. If your connected devices do not provide sufficient power to run the switch, you must connect the included Type-C power cable to the dedicated "DC 5V" port to ensure stable video output and prevent screen flickering.
