6. Operating Instructions

Switching Between Computers

You can switch between Computer 1 and Computer 2 using one of two methods:

• Device Button: Press the Switch Button (PC1-PC2) on the front panel of the KVM switch.
• Wired Extension Button: Press the button on the connected wired extension control.

The Input Channel LED will illuminate to indicate which computer is currently active.

Display Modes

The KVM switch supports two primary display modes for your monitors:

• Extended Working Mode: Each monitor displays different content, extending your desktop workspace. This mode requires your computer's operating system and graphics card to support extended displays.
• Copy Working Mode (Duplicate): Both monitors display the same content, mirroring your desktop.

You can configure these display modes through your computer's display settings (e.g., Windows Display Settings or macOS System Settings).

Operating System Specifics

Image: Various display configurations for Windows, including extended and duplicate modes. Also shows macOS configurations, noting that MacBook USB-C ports may not support extended display (ABC Mode).

• Windows: Supports both extended and duplicate display modes across two monitors. Ensure your computer has two HDMI ports or appropriate adapters if not using DisplayPort directly.
• macOS: The MacBook USB-C port may not support extended display (ABC Mode). In some macOS configurations, especially with ARM processors, only mirror or duplicate display modes might be available.
