Dual 4K 60Hz USB-C to HDMI Display Adapter with DisplayLink DL-6950 Controller, 100W Power Delivery Pass-Through, USB-A/C Compatibility, and TAA Compliance
The StarTech 109B-USBC-HDMI is a USB-C to HDMI adapter that adds two independent 4K 60Hz HDMI displays to any USB-C or USB-A laptop through a DisplayLink DL-6950 controller, enabling dual extended monitors on Apple M1, M2, M3, and M4 MacBooks that cannot natively drive more than one external display. The adapter delivers 100W USB Power Delivery 3.0 pass-through with 90W available for laptop charging, supports 5.1-channel HDMI audio, and works with Windows, macOS, Ubuntu, and ChromeOS. A DisplayLink-certified USB-C to dual HDMI adapter from StarTech with TAA compliance, aluminum enclosure, bus-powered operation, and a 3-year warranty.
The integrated USB-C to USB-A adapter provides host connectivity to both port types without a separate dongle, and the 1-foot attached cable with strain relief reduces connector wear during daily use. Fast Role Swap prevents USB data disruption when switching between wall power and bus power, and the aluminum enclosure provides EMI shielding and heat dissipation for stable dual-display output during extended work sessions.
Where the 109B-USBC-HDMI Fits
- MacBook dual-display workstations where DisplayLink enables two independent 4K 60Hz monitors on Apple M-series MacBooks that natively support only one external display, adding the screen real estate needed for development, design, and financial workflows
- Government and TAA-compliant deployments where TAA compliance, DisplayLink certification, and cross-platform support across Windows, macOS, Ubuntu, and ChromeOS meet federal procurement requirements for dual-monitor workstations
- Mobile professionals and travel setups where the 4.3-ounce bus-powered adapter with 100W PD pass-through replaces a bulky docking station for dual-display capability at hotel desks, coworking spaces, and conference rooms
