# Display specifications

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

## Display features

Tab IQ-9075
Tab IQ-8275

**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
- Type-C over DisplayPort

**Capabilities**

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

Table: Interfaces and capabilities

| **Interface** | **Capabilities** |
| --- | --- |
| DSI0 | FHD+ (1200 × 2520) at 120 fps (8-bit)<br><br><br>Supports Video Electronics Standards Association (VESA) display stream compression (DSC) 1.2 |
| DSI0 to HDMI | Supports up to 3840 × 2160 at 30 fps<br><br><br>Supports dynamic resolution switch up to  3840 × 2160 at 30 fps |
| DisplayPort | 3840 × 2160 resolution at 30 fps, 24 bpp (requires two lanes at HBR3)<br><br><br>Single stream transport |
| eDP | Supports a maximum resolution of 3840 × 2160 at 60 fps |
| Maximum concurrency | HD+ (1200 × 2520) (8‑bit) at 60 fps with DSI primary + 4K at 30 fps DisplayPort<br><br><br>Or<br><br><br>1920 × 1080p at 60 fps with DSI to HDMI primary + 4K at 30 fps DisplayPort<br><br><br>Or<br><br><br>1920 × 1080p at 60 fps with eDP primary + 4K at 30 fps DisplayPort |

**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.
