3-Port USB-C DisplayPort Hybrid KVMP™ Switch



The ATEN CS1953 is a hybrid KVMP™ Switch that integrates USB-C device and DisplayPort PC into a desktop workstation. Taking a giant step forward from prior digital-interfaced KVM models, the CS1953 comes with USB Type-C functionality that transfers video, audio, data, and even provides USB Power Delivery 3.0 for USB-C device charging. That means with a single USB-C cable, users can reduce bulky cable setups and experience a better working environment.

Complying with DisplayPort 1.2 standard, the CS1953 supports superior video quality up to 4K DCI (4096 x 2160 @ 60Hz) for premium images. In addition, its USB-C channel supports DP Alt Mode, so it can deliver DisplayPort signals and work like a standard DisplayPort connection. For added flexible usage, the CS1953 can convert signals from DisplayPort to HDMI or DVI with its DisplayPort Dual-Mode technology (DP++).

Featuring these robust functionalities and an unbeatable combination of USB 3.1 Gen 1 data transfer speed convenience, bus-powered design, and user-friendly port switching methods including hotkeys, mouse and remote port selector etc., the CS1953 allows users to keep up with the latest innovations in desktop multimedia and work smarter than ever.
