Two-computer DisplayPort KVM
The ATEN CS1922M is a 2-port USB 3.0 4K DisplayPort MST KVM switch that lets one user control two computers from a single keyboard, mouse and audio setup. It includes two DisplayPort 1.2 cables, two USB 3.0 cables and four audio cables in the box. The unit supports video resolution up to 4096 x 2160 and USB 3.1 Gen 1 data rates up to 5 Gbps.
Multi-display users versus single-screen setups
This switch suits users who need an extended desktop or splitter mode across two monitors driven from one DisplayPort 1.2 source. It also fits workflows that require independent switching so the KVM focus stays on one computer while USB peripherals remain on the other. Buyers who only need to share a single display between two systems should look at a standard 2-port KVM without MST.
Built-in MST hub for dual DisplayPort consoles
The deciding specification is the integrated Multi-Stream Transport hub that creates two console DisplayPort outputs from a single DisplayPort 1.2 input. This enables dual-monitor operation at 4K resolution without a second video card or additional cabling. If the workflow does not require two displays from one source, the MST capability adds no benefit.

Questions about this item
Do I need to provide my own DisplayPort 1.2 cables and USB 3.0-A to USB 3.0-B cables to connect two computers?
No, the package includes two DisplayPort 1.2 cables at 1.5 m each and two USB 3.0-A to USB 3.0-B cables at 1.8 m each, so both computers can be connected immediately.
Can I keep an older monitor that only accepts HDMI while using the DisplayPort MST feature for a second display?
Yes, the switch provides one HDMI port alongside three DisplayPort connectors, allowing an HDMI monitor to be used together with a DisplayPort MST extended desktop.
How can I confirm the USB 3.1 Gen 1 hub is delivering 5 Gbps after setup?
Connect a USB 3.0 storage device, run a large file transfer, and verify the sustained throughput approaches 5 Gbps in the operating system's performance monitor.
