5. Operating Instructions

The KVM switch offers multiple ways to switch between connected computers.

5.1 Switching Methods

• Front Panel Buttons: Press the '1' or '2' button on the front panel of the KVM switch to select the corresponding computer (PC1 or PC2).
• External Wired Controller: Press the button on the external wired controller to switch between PC1 and PC2. This is convenient for placing the KVM out of sight.

5.2 Display Modes

The KVM switch supports both Extended and Copy (Mirror) display modes, depending on your computer's display settings.

This image illustrates the two primary display modes supported by the KVM switch: Extended working mode, where the desktop is spread across two monitors, and Copy working mode, where the same content is mirrored on both monitors. The KVM switch facilitates these configurations for connected computers.

• Extended Mode: Each monitor displays a different part of the desktop, extending your workspace. This is typically the default and most common setup for productivity.
• Copy (Mirror) Mode: Both monitors display the exact same content. This mode is useful for presentations or sharing the same view.

To configure display modes, adjust the display settings within your operating system (Windows, macOS, Linux).

5.3 LED Indicators
