SMI “Displays” Their SoC Technology with SM770 Chipset
SMI (Silicon Motion Inc.) has introduced a new chip that allows multiple 4K displays to connect to a single host computer. The SM770 chip is what SMI calls a high-performance USB display interface, or system-on-chip (SoC).
The promise is straightforward: run three concurrent 4K UHD displays from one host system without noticeable latency. The new SMI chip includes a user-friendly InstantView software application designed to manage and configure multi-display setups. One of the more attractive points is that it does not require a traditional display driver, which helps avoid the long-term maintenance headaches that often come with driver dependencies.
The SM770’s feature set includes:
- Support for triple 4K (3840 × 2160) @60Hz, with support up to 144Hz displays
- Second-generation CAT technology delivering reduced-latency codec performance
- USB 3.2 Gen2 (10Gbps)
- Support for displays over USB, Ethernet, or wireless
- Operating system compatibility: Windows, Linux, macOS, Android, and ChromeOS
USB docking stations have become essential for professionals who rely on multi-screen workflows. The SM770 is clearly positioned to improve that experience by reducing latency and improving overall system efficiency. This type of technology supports the next generation of high-quality USB docking stations and display adapters built for demanding modern work environments.
At the time of writing, the chips are available for sampling, but we have yet to see a finished consumer product using the SM770 in the wild. If SMI (or any partner) has a shipping product, we’d genuinely like to hear about it.
