The display subsystem is a software component that enables high-quality graphics and
            video output on devices. The subsequent sections explain the key features of the display
            subsystem along with the capabilities, advanced features, and limitations.

The display subsystem supports the following:

- Upstream Wayland protocol with extended support from Qualcomm
- Weston with Snapdragon Display manager (SDM) backend module
- DSI 1.2
- DisplayPort over USB Type-C (SST)
- eDP1.4 for embedded panels
- MIPI DSI D-PHY

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

## Advanced features

The display subsystem is designed to enhance the visual performance and efficiency of the
            device. The advanced features are currently available to users who have full access to
            the proprietary software shipped with Qualcomm Linux. For more information, see the
                [Qualcomm Linux Display Guide - Addendum](https://docs.qualcomm.com/bundle/resource/topics/80-70014-18A/features.html).

## Limitations

Source: [https://docs.qualcomm.com/doc/80-70014-18/topic/features.html](https://docs.qualcomm.com/doc/80-70014-18/topic/features.html)

A common constraint is that the DSI and the embedded DisplayPort (eDP) cannot work at the
            same time. Only one of them can power up the primary panel at any given moment.
