The ATEN KVMP Switch CM1284 is a professional 4-Port USB 4K HDMI Multi-View KVMP™ Switch designed for real-time monitoring and seamless control of multiple computer systems from a single console. Supporting up to four HDMI computers and two HDMI displays, it enables users to monitor, switch, and manage multiple video sources simultaneously with independent keyboard and mouse control.
The ATEN KVMP Switch CM1284 delivers exceptional visual performance with support for resolutions up to 4K DCI (4096 × 2160 @ 30 Hz). Its dual-display architecture provides maximum flexibility by allowing users to display multiple video sources on the primary monitor while presenting a selected source in full-screen mode on the secondary monitor.
To improve productivity, the switch offers multiple viewing layouts, including Quad View, Picture in Picture (PiP), Picture by Picture (PbP), Picture on Picture (PoP), and Full Screen mode. Users can resize and reposition display windows to create a customized monitoring environment that fits their operational requirements.
One of the standout features of the ATEN KVMP Switch CM1284 is Boundless Switching, an exclusive ATEN technology that allows users to switch between connected computers simply by moving the mouse cursor across display windows. This intuitive control method significantly reduces switching time and improves workflow efficiency during time-sensitive operations.
The integrated 2-port USB hub allows connected computers to share USB peripherals independently of the KVM focus, while separate switching for USB devices, audio, and KVM functions provides greater flexibility for multitasking. In addition, Video DynaSync™ and EDID Expert™ technologies ensure optimized display resolution, smooth startup, and stable video output across different connected devices.
