Plugable USBC-7400H4 Quad 4K HDMI Graphics Adapter
The Plugable USBC-7400H4 connects up to four independent HDMI displays at 4K 60Hz via a single USB-C, USB4, or Thunderbolt port. Powered by the DisplayLink DL7400 chipset, it solves multi-monitor limitations on Windows and macOS, including Apple Silicon M1/M2/M3/M4/M5 MacBooks.
Why Only Two Monitors on Mac? Setup and Troubleshooting
Many Mac users expect all four displays to work instantly, but macOS may require DisplayLink driver installation and certain system permissions. Ensure you have the latest driver from Plugable and have granted the necessary screen recording permissions. Also verify that your USB-C port supports the data throughput required.
DisplayLink Technology for Unmatched Expandability
DisplayLink offloads graphics processing via software, bypassing native GPU limits. This lets you add more monitors than your GPU natively supports, ideal for data analysts, financial users, and creative professionals.
Power Delivery Passthrough
With 100W USB-C PD passthrough, you can charge your laptop while the adapter is connected, so you don't lose a power port. The adapter is bus-powered, but for maximum performance, use the included power supply (if provided) or ensure your host supplies enough power via PD.
Compatibility and Selection
Works with Windows 11/10 and macOS 11 and later. For best results on Mac, use USB-C or Thunderbolt ports. When choosing a multi-display adapter, consider the operating system, number of displays, and whether you need charging passthrough.
