You've got four workstations on one desk and you're still reaching for the wrong keyboard, unplugging monitors, or paying someone to reconfigure your setup every time you need to hop between machines. That's not a workflow. That's friction.
The ATEN CS1944DPA kills that problem in one afternoon. One USB keyboard, one mouse, four DisplayPort computers. You press a button on the switch (or the remote, or use a hotkey) and you're on the next machine. Peripherals stay connected. Audio follows. No re-plugging, no driver headaches.
Video output is genuinely 8K-class: up to 7680×4320 at 60 Hz per port, with HDR 10+ and HD Audio over DisplayPort 1.4. If you're running a design workstation next to a finance terminal next to a test rig, this keeps every one of them crisp without a separate monitor stack.
Two USB 3.1 Gen 1 ports (5 Gbps) share your peripherals across all four machines. Hot-plug supported, so you can swap a scanner or a card reader mid-session without rebooting anything.
What's in the box: eight DisplayPort cables (1.5 m), four USB Type-A to Type-B cables (1.8 m), four mic cables, four speaker cables, a remote port selector, and a power adapter. You don't need to buy a single extra cable to get this running.
Works with Windows, Mac, and Linux. Firmware upgradable when ATEN pushes compatibility fixes. Multilingual keyboard mapping covers English, Japanese, French, and German layouts.
Five units on the shelf right now. If you're running a multi-PC desk, a lab bench, or a small IT ops station, this is the switch that makes four machines feel like one
