Dual HDMI expansion

The SWITCHFLUX USB 3.0 to Dual HDMI adapter adds two HDMI ports to a single USB-A connection, letting laptops, PCs and desktops drive two external monitors at once. It supports Windows 10, 11 and macOS, though a driver must be installed before the displays become active. The aluminum shell and nylon-braided cable are built for regular transport and frequent plugging. Gold-plated connectors resist wear from repeated insertion cycles.

Resolution headroom

On a USB 3.0 port each output can reach 1080P at 60 Hz, giving enough headroom for office applications, web browsing and video playback across both screens. If the host only provides USB 2.0, the maximum drops to 800 by 600 or the video signal may not appear at all. The adapter handles mirror and extended desktop modes on both supported operating systems, with macOS gaining an ABC-style extended layout across the two monitors.

USB 3.0 bandwidth limit

The practical ceiling is the 5 Gbps bandwidth of the USB 3.0 link, which caps total pixel throughput to two 1080P60 streams and prevents higher resolutions or refresh rates. macOS does not support native MST, so the driver implements a proprietary extension mode that consumes additional host resources. Systems without an available USB-A 3.0 port or the ability to install kernel-level display drivers cannot use this adapter.

Questions about this item

Will the adapter run two monitors at 1080P 60 Hz on my older laptop that only has USB 2.0 ports?

No. USB 2.0 ports drop the resolution to 800×600 or may not output video at all. A USB 3.0 port is required for full 1080P at 60 Hz on both screens.

How can I confirm the adapter is driving both screens correctly after installing the driver?

Open display settings on Windows 10, 11 or macOS and verify each external monitor is detected and set to 1080P at 60 Hz in either extended or mirror mode.

Does the package include the two HDMI cables I need to connect my monitors, or do I buy them separately?

The box contains only the USB 3.0 to Dual HDMI adapter itself. Two HDMI cables must be purchased separately to link the adapter to your monitors.
