Outstanding video quality – up to 4K. The ATEN CS19216 16-Port USB 3.0 4K DisplayPort KVM Switch can effectively access and control up to 16 DisplayPort computers using a single USB keyboard, USB mouse, and monitor console. With its dual-interface console, users can choose between DisplayPort/HDMI video output, which supports high video quality up to 4K DCI (4096 x 2160 at 60 Hz) and delivers crystal-clear images. To meet the demands for easy expansion and flexibility, the CS19216 can be cascaded in two tiers to control up to 256 computers from a single console. Additionally, the CS19216 supports multi-display functionality by stacking up to eight CS19216 units, allowing users to compare and analyze information across a maximum of eight monitors, significantly streamlining the work environment. With two patented ATEN technologies – Video DynaSync™ and EDID Expert™, the CS19216 can optimize screen resolution, accelerate switching between ports, and power on devices cleanly while avoiding issues during screen boot-up.
