Dual-Display USB to HDMI Video Adapter with 4K 30Hz and 1080p HDMI Outputs, USB-A and USB-C Compatibility, and Bus-Powered Operation for Laptops and Desktops
The StarTech 107B-USB-HDMI is a USB to HDMI adapter that adds two independent HDMI displays to any laptop or desktop through a single USB 3.2 Gen 1 port, delivering 4K 30Hz on one output and 1080p on the other for extended dual-monitor productivity. The adapter works with both USB-A and USB-C hosts through an integrated USB-C dongle, runs bus-powered without an external power supply, and supports Windows, macOS, and ChromeOS across all major laptop and desktop brands. A dual-display USB to HDMI adapter from StarTech with ultrawide support up to 3440x1440 60Hz, 2-channel HDMI audio, LED status indicator, and a 3-year warranty.
The 4.3-inch attached USB cable keeps the adapter close to the laptop while providing enough clearance for both HDMI cables, and the compact 2 x 3.9 x 0.6-inch form factor fits in any laptop bag for mobile or travel use. Automatic driver installation on Windows and ChromeOS means plug-and-play setup with no software downloads required, and the adapter supports extended and mirrored display modes across both outputs for flexible multi-monitor configurations.
