ATEN 2-Port 4K DisplayPort Dual Display Mini-Matrix Boundless KVM Switch

The CM1942 is a 2-port 4K DisplayPort dual-display mini-matrix Boundless KVM switch that combines a DisplayPort switch and a 2-port USB 3.1 Gen 1 hub to provide access to two DisplayPort computers from a single USB/HDMI console. It supports two PC operation modes: Single PC Mode, which displays the focused PC across both monitors, and Dual PC Mode, which displays each PC on a separate monitor regardless of KVM focus. The switch supports video resolutions up to 4K DCI (4096 x 2160 @ 60 Hz) and includes a built-in SuperSpeed USB 3.1 Gen 1 hub for peripheral connection and high-speed data transfer.

Advantages

The CM1942 enables quick switching between two computers using pushbuttons, hotkeys, mouse wheel, mouse cursor, or a remote port selector. Boundless Switching lets the user move the mouse cursor across screen borders to change video source seamlessly. Video DynaSync™ optimizes display resolution and eliminates boot-up display problems. Audio Mixer Mode can mix up to two audio sources into a single output. The console supports keyboard and mouse emulation or bypass for broad driver and multifunction device compatibility, plus multilingual keyboard mapping for English, French, Japanese, and German layouts.

Choose Single PC Mode to mirror one computer across both monitors or Dual PC Mode to display each computer on a separate monitor. Switch between computers using the front-panel buttons, keyboard hotkeys, mouse wheel or by moving the mouse cursor across displays when Boundless Switching is enabled. Connect peripherals to the built-in USB 3.1 Gen 1 hub; peripheral switching is independent of KVM focus.

Recommendations

For optimal results use DisplayPort 1.2–compliant cables and monitors capable of 4K DCI @ 60 Hz. Use high-quality USB 3.1 cables for connected peripherals to ensure SuperSpeed data rates. Verify HDCP settings on source devices when playing protected content.
