How to use

Connect the adapter to a host device using the USB-C connector that supports DisplayPort Alt Mode. Attach up to two HDMI cables from the adapter to external displays. If power is needed for the host, connect a USB-C PD charger to the adapter’s power input so the adapter can pass through up to 100W of power. Configure display settings on the host operating system to select extended or mirrored modes and adjust resolution and refresh rate as required.

Recommendations

Use high-quality HDMI cables rated for 4K@60Hz to ensure stable video output. Verify that your laptop or device supports DisplayPort Alt Mode over USB-C and that system firmware and graphics drivers are up to date for optimal multi-display performance. When using high power draw peripherals, confirm the connected PD charger can supply sufficient wattage to the host device.
