**Key features**

The display subsystem supports the following key features:

- Wayland and Weston with upstream aligned protocol
- Weston with direct rendering manager (DRM) backend module
- Weston remote desktop protocol (RDP) backend
- DSI interface
- Native eDP 1.4 interface

**Capabilities**

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

**Advanced features**

The display subsystem enhances the visual performance and
efficiency of the device. A key feature of the display subsystem is to
provide improved picture quality with HDR10 support for internal
display. This feature is available to licensed developers with authorized access.
