The Accell ultra DisplayPort multi-display MST hub allows you to connect 2 DisplayPort monitors from a single DisplayPort output. The multi-display hub utilizes multi-stream transport (MST) protocol, supporting up to 2 displays independently at 2560x1600 at 60Hz (reduced blanking) or 3840x2160 at 30Hz (reduced blanking) each with DP 1. 2. Expand your display beyond the compact display integrated into your notebook computer. Now you can easily dedicate each big-screen, high-resolution display to a separate application, providing the efficiency and productivity of multi-tasking. Don't have 2 DisplayPort monitors? The MST hub is dual-mode or also known as DisplayPort++ and can directly output single-link HDMI, VGA, and DVI signals using either a passive or active adapter. Accell MST hub makes it easy and cost-effective to use multiple monitors.
