## 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)
* 2x DisplayPort with single stream transport (SST) and 2x DisplayPort with multi-stream transport (MST)

The following figure shows the IQ-9075 display processing unit (DPU) interfaces and their connectivity.
