Dual HDMI USB Adapter for Laptop Productivity

This USB to Dual HDMI Adapter connects two independent displays — one at 4K 30Hz and one at 1080p — through a single USB 3.2 Gen 1 Type-A port. An integrated USB-A to USB-C dongle broadens host compatibility across Windows, macOS and Chrome OS systems. It targets professionals who need extra screen space for business applications on laptops or docks lacking native video outputs. The adapter is bus-powered and includes a 4.3in attached cable for portable use.

Silent Bus-Powered Operation

The adapter draws all power from the host USB port, so no external supply is needed and no fan is present. Silicon Motion Content Adaptive Technology keeps CPU usage low and latency minimal for smooth window and mouse movement during typical office workloads. Because the device has no moving parts, it adds no audible noise to the workspace. Power consumption stays within the limits of a standard USB 3.2 Gen 1 connection.

Integrated Dongle and Short Cable Simplify Setup

The built-in USB-A to USB-C dongle lets the same adapter plug into either port type without carrying a separate converter. The fixed 4.3in (11cm) cable keeps the connection tidy at a desk or in a meeting room. No driver CD or software suite is bundled; the adapter relies on native OS support for Windows 7 through 11, macOS 10.14 through 13.0 and Chrome OS. This makes deployment straightforward for IT teams managing mixed fleets.

Questions about this item

How do I install the 107BUSBHDMI and what step do people often miss?

Connect the integrated 4.3in cable to a USB 3.2 Type-A port or use the attached USB-A to USB-C dongle for USB-C hosts, then install the DisplayLink driver from the StarTech website before the operating system will recognise the two HDMI outputs.

What maintenance or replacement will the 107BUSBHDMI need later?

The adapter is bus-powered with no internal battery or fan, so no scheduled maintenance is required; only the DisplayLink driver may need updating when Windows, macOS or Chrome OS release major version upgrades.

What limit appears first under sustained use of the 107BUSBHDMI?

The USB 3.2 Gen 1 5Gbps bandwidth caps the combined output at one 4K 30Hz stream plus one 1080p stream, so extended heavy desktop work will hit that throughput ceiling before thermal throttling occurs.
