The ATEN CS1964 optimizes your desktop organization to help you effortlessly manage a triple-display multimedia workstation. The CS1964 provides instant, user-friendly access to four computers via a single USB keyboard, USB mouse and three HDMI monitors. By daisy-chaining two CS1964 for six displays, you can multitask smoothly to increase productivity and improve workflow.

The CS1964 is equipped with patented ATEN technology – Video DynaSync™ – which optimizes display resolution, speeds up switching between systems, and ensures that windows opened on an extended desktop will not revert to their default configurations on the main display when switching between ports, providing a smooth and uninterrupted user experience. What’s more, the CS1964 supports the most superior video quality up to 4K DCI (4096 x 2160 @ 60Hz). In addition, the CS1964 delivers data transfer rates up to 5 Gbps with a built-in USB 3.1 Gen 1 hub, allowing you to accelerate multimedia operations with ease, and equipped with N-key Rollover, offering support for up to 15 simultaneous keystrokes that avoids ghosting or jamming.

Integrating all these advanced functionalities, the CS1964 provides a unique advantage for users who need to operate multiple systems and perform multiple tasks across a triple-display extended desktop. The CS1964 especially benefits those doing financial trading, CGI work, graphic design, control center, call center, video post production, gaming applications, and more.
