Important Note for 4K@60Hz Resolution:

To achieve the maximum resolution of 4096*2160@60Hz, ensure that both your source devices (computers) and all HDMI cables used support 4K@60Hz. Using lower specification cables or devices may result in lower resolutions.

5. Operating Instructions

Switching Between Computers:

You can switch between the two connected computers using one of the following methods:

• Panel Button: Press the KEY 1 or KEY 2 button on the front panel of the KVM switch to switch to the corresponding computer. The LED indicator will illuminate to show the active PC.
• Wired Desktop Controller: Press the button on the wired desktop controller to switch between PC1 and PC2.

Display Modes:

The KVM switch supports three primary display modes:

• Extended Mode: This mode allows you to display different content on each of the two connected monitors, extending your desktop across both screens.
• Duplicate Mode (Mirror Mode): In this mode, both monitors will display identical content, mirroring the same desktop.
• Splicing Mode: This mode combines the two monitors to act as one large virtual display, allowing a single image or application to span across both screens. Note: Splicing Mode requires specific graphics card functions, such as NVIDIA's 'Surround Function' or AMD's 'Eyefinity Function', to be enabled on your computer.

  • Ensure the KVM switch is receiving adequate power from the power adapter.
• Switching Issues:
  • Confirm that the desktop controller is properly connected.
  • Ensure the KVM switch is powered on.
• Resolution/Refresh Rate Problems:
  • Check your computer's display settings to ensure the correct resolution and refresh rate are selected.
