Q&A
Q: Why should I choose this instead of a USB-C hub or Docking station?
Most hubs and docks rely on DisplayPort Alt Mode, which limits the number of external displays and varies by laptop model. This adapter uses DisplayLink technology, allowing you to reliably drive four external displays from a single USB-C port, even on systems that normally support only one or two monitors. This makes it ideal for standardized large scale IT deployments across mixed hardware. It focuses on what professionals actually need - quad 4K display support, high wattage charging, and a useful USB A port - without unnecessary additional ports.
Q: Will this charge my laptop?
A: Yes. It supports up to 140W USB C Power Delivery passthrough, keeping your laptop charged while powering four 4K displays and connected peripherals. Please note that 10W is reserved for the adapter, providing a maximum of 130W to the host.
Q: What USB devices can I use with it?
A: The built in USB A 2.0 port is ideal for a Bluetooth keyboard/mouse adapter, but can also support USB webcams, flash drives, or any other USB A 2.0 device that fits your workflow.
Q: Is this compatible with Windows and Mac?
A: Yes. It uses DisplayLink Pro DL 7400 technology, ensuring broad OS support. Ensure you have the latest DisplayLink drivers installed on your system for optimal performance. DisplayLink also enables multi-monitor setups on Apple Silicon systems (M1 / M2 / M3/ M4/ M5) once the DisplayLink software is installed and running (manual driver installation is required for macOS devices).
Q: Why does macOS request “Screen Recording” permission?
A: macOS requires this permission for DisplayLink to create and manage virtual displays. This is a system-level requirement and does not mean your screen is being recorded or transmitted. Granting this permission is necessary for external monitors to function properly.
Q: Can I use my laptop’s built-in display at the same time?
A: Yes. Your internal laptop display can remain active alongside the four external monitors, allowing for 5-screen workflows depending on your system configuration.
