Silicon Motion's SM768 USB display SoC enables multiple displays up to 4K ultra high definition through USB interface. Target applications include USB universal docking stations, USB adapters, USB portable monitors, video walls and wireless displays.

With Silicon Motion's InstantView® technology, users of docking stations can instantly mirror their computer screen to any external displays without the need to install a display driver. Docking stations based on the SM768 solution combine high graphics performance with low CPU loading and low power consumption. The CAT™ (Content Adaptive Technology) compression technology offers a high compression ratio while maintaining great image/video quality.

Silicon Motion provides reference designs that help manufacturers reduce development time and shorten their time-to-market. Silicon Motion also provides all turn-key software for customers. SW is compatible with major OS including Windows, macOS, ChromeOS, Android and Linux.

CAT™ (Content Adaptive Technology)

Silicon Motion's CAT™(Content Adaptive Technology) uses multiple image/video processing algorithms to compress display data and minimize bandwidth usage. At the same time, CAT uses minimal host CPU usage to achieve low latency and high-quality displays.

By offloading much of the compression work to a hardware accelerator, the CAT technology both runs faster and imposes less loading on the CPU. As will be shown later, this helps the SM768 to achieve very low CPU loading.


Enabling USB docking station Plugin and Display

Silicon Motion has developed new InstantView software application that seamlessly configures the host content for viewing on any display, with no need for display drivers installation.

Instantview Screen

The InstantView software supports instant screen mirroring to displays. The software also supports Extended Display option. Whether the user chooses the mirrored or extended display option, the entire display operation is controlled via the intuitive and user-friendly InstantView user interface. And eliminates the need for IT support call.

The InstantView application will remain running on the host computer to enable truly plugin and display user experience. InstantView will automatically update itself when newer version becomes available. And will also update firmware on the docking/adapters to keep your device always running at top condition.
