Switching Between Computers:

• Front Panel Button: Press the 'Select' button on the front panel of the docking station to switch between PC1 and PC2. The LED indicator will show which computer is currently active.
• Desktop Controller: Press the button on the external desktop controller to switch between PC1 and PC2. This allows for switching even if the docking station is placed out of reach.

Note: Keyboard shortcuts (hotkeys) are not supported for switching.

Display Modes:

The docking station supports various display configurations for Windows and macOS systems:

• Windows: Supports dual screen docking mode (two monitors output different images) and dual screen mirroring mode (two monitors output the same image). Extended display (MST) is fully supported.
• macOS: Only supports mirroring mode. Due to macOS limitations, the USB-C port does not support extended display (MST).

EDID Emulation:

The KVM switch features EDID emulation, which helps maintain display settings and prevents resolution and icon rearrangement when switching between computers or when a computer wakes from sleep. This ensures a consistent desktop experience.
