ATEN CM1284

4-Port USB 4K HDMI Multi-View KVMP™ Switch

The ATEN CM1284 is a 4-Port USB HDMI Multi-View KVMP™ Switch that delivers powerful control and real-time monitoring for up to four HDMI-enabled computers from a single workstation. Built for high-efficiency, multi-system environments, it enables users to view and control multiple systems simultaneously through a flexible multi-view interface while maintaining seamless interaction via one keyboard and mouse set. With support for advanced video resolutions and an intuitive user interface, the CM1284 is a compact yet professional-grade solution for control rooms, broadcasting stations, medical monitoring, and financial trading environments.

At the core of the CM1284’s functionality is its ability to display up to four video sources in various modes: Quad View, Picture-in-Picture (PiP), Picture-by-Picture (PbP), Picture-on-Picture (PoP), or Full Screen. These display modes offer adaptable viewing based on user preference or operational priority. The switch supports resolutions up to 4096×2160 @ 30Hz, with crystal-clear video quality through HDMI 1.4, including Deep Color and Dolby True HD audio. Whether used for real-time surveillance, live video feeds, or managing multiple virtual machines, the CM1284 ensures high-definition clarity across all input sources.

One of its most standout features is Boundless Switching, a function that allows seamless control of all connected systems simply by moving the mouse cursor across window borders on the multi-view screen. This provides intuitive and instantaneous access to each computer, eliminating the need for hotkey combinations or OSD toggling. The experience is further enhanced with Video DynaSync™, which ensures that monitor settings such as resolution and refresh rate remain consistent when switching between systems—eliminating screen flickering or image distortion.

The CM1284 is equipped with EDID Expert™ technology, which simplifies display compatibility by managing Extended Display Identification Data (EDID) across all sources. Users can choose between default, factory-set, or dynamic EDID modes depending on their setup needs, ensuring that video settings are negotiated properly between the source computers and connected displays.

To boost system scalability, the CM1284 supports Daisy Chain Control (DCC) and cascading. DCC allows up to three CM1284 units to be chained, offering centralized control of up to 12 sources. For even larger operations, cascading two levels deep enables real-time control and visual monitoring of up to 16 sources in a single multi-view grid. This architecture is particularly useful in command centers or broadcast setups where multiple data or video streams must be accessed concurrently.

Beyond video switching, the CM1284 features a 2-port USB 2.0 hub that allows for independent USB peripheral sharing. This enables connected computers to access devices like printers, flash drives, or touch panels, regardless of which system is in control. Additionally, independent audio switching allows the user to listen to audio from one computer while working on another—ideal for tasks involving alerts or simultaneous audio monitoring.

Control options are abundant and user-friendly. The CM1284 can be operated via front-panel pushbuttons, IR remote, keyboard hotkeys, on-screen display (OSD), or RS-232 serial commands. This multi-interface access ensures compatibility with existing control systems and diverse operational environments. The device also supports firmware upgrades via USB, giving users long-term flexibility and future-proofing.

Physically, the CM1284 comes in a durable metal chassis (1U rack-mountable), measuring approximately 43.7 x 16.4 x 4.4 cm and weighing about 2.46 kg. Designed for mission-critical operations, it supports auto-scan, hot-plugging, multilingual keyboard mapping, and power-on detection—ensuring consistent performance, even in mixed Windows/Mac/Linux environments.

In summary, the ATEN CM1284 is not just a KVM switch—it’s a smart multi-view console controller for demanding workflows. Its combination of real-time video display, intuitive mouse-based control, scalable architecture, and independent USB/audio switching makes it an indispensable tool for professionals who need to manage multiple systems with precision, flexibility, and speed. Whether you’re building a 24/7 control room or running complex live operations, the CM1284 offers the reliability and control necessary to stay ahead.
