FLEANE USB 3.0 Dual HDMI Adapter

This USB 3.0 to Dual HDMI adapter adds two external displays to a laptop or desktop through a single USB 3.0 port. It uses the SiliconMotion SM768 chip to drive both outputs. The adapter works with Windows and Mac OS after the required SiliconMotion driver is installed. It suits users who need extra screen space for multitasking.

Upgrade from single-display USB video

The adapter replaces a single-output USB graphics device by enabling mirror mode and extended modes such as A-B-B and A-B-C on Windows and Mac OS. It lifts the Mac OS video extension limit so two large screens can be driven simultaneously. The jump is worthwhile when one extra monitor is no longer enough for the workflow.

Sustained dual-monitor operation

Port 1 delivers up to 4K at 30 Hz while Port 2 reaches 1080P at 60 Hz during continuous use. The SM768 chip maintains stable output across both ports without dropping frames in extended desktop scenarios. Driver installation is required before plug-and-play operation begins.
