## Display features

**Key features**

The display subsystem supports the following key features:

* Wayland and Weston with upstream protocol
* Weston compositor with direct rendering manager (DRM) backend module
* Display serial interface (DSI)
* 2xDisplayPort with single stream transport (SST) and 2xDisplayPort with multi-stream transport (MST)

**Capabilities**

The device supports two displays simultaneously and offers various configurations for maximum concurrency. The following table summarizes the capabilities:
