5.2 Display Modes (Extended vs. Mirrored)

The KVM switch supports two primary display modes, provided your connected computers and graphics cards support multi-screen output:

• Extended Mode: Each of the three monitors displays a different part of your desktop, extending your workspace. This mode requires your PC to output three distinct video signals.
• Mirror Mode (Copy Mode): All three monitors display the same content, mirroring your desktop across all screens. This mode requires your PC to duplicate the video signal across three outputs.
