ATEN 4-Port USB HDMI Multi-View KVMP Switch

The ATEN CM1284 4-Port USB HDMI Multi-View KVMP™ Switch enables control of four computers from a single keyboard, mouse and dual-monitor console while supporting HDMI video up to 4K (4096 x 2160 @ 30 Hz). It provides multi-view display modes and independent keyboard/mouse control for each connected system, and is designed for rack mounting in environments that require real-time monitoring.

Advantages

The switch offers dual console outputs: one output supports Quad View, Picture in Picture (PiP), Picture by Picture (PbP) and Picture on Picture (PoP) modes while the other supports Full Screen mode, allowing simultaneous multi-source viewing and a dedicated full-screen display. Boundless Switching lets operators move the mouse cursor across windows to switch control between video sources. Daisy Chain Control (DCC) and cascading extend control to additional CM1284 units, enabling up to 16 video sources to be selected, switched and displayed from a single console. The unit supports HDMI video at resolutions up to 4096 x 2160 @ 30 Hz and features a robust metal housing suitable for rack integration.

Recommendations

For stable 4K display performance, use high-quality HDMI cables rated for 4K and ensure source computers support the selected resolution and refresh rate. When deploying multiple units in a cascade, label connections and verify DCC settings to maintain clear control mapping across all systems.
