DisplayLink Direct
Connect and drive multiple displays over USB using DisplayLink® technology.
📖 Read the Documentation »
Overview DisplayLink Direct is an SDK that lets applications render content directly to DisplayLink-connected displays. DisplayLink (developed by Synaptics) encodes and transmits video over standard data buses, such as USB 2.0 and USB 3.x, without relying on native video pass-through such as DisplayPort Alt Mode or Thunderbolt. The SDK provides C/C++ headers and language bindings so you can integrate multi-display output into your own applications. Features
Drive multiple displays over a single USB connection. Use the C/C++ API or Python bindings. Render Qt applications to DisplayLink displays with the Qt platform plugin. Get started with ready-to-run samples, including a video wall and EDID reader. Deploy without host-side drivers or compositor integration, making the SDK suitable for embedded systems and other use cases that need a lightweight solution. Configure and integrate multi-display output quickly with the simple, easy-to-use API.
