Operating Instructions

Switching Between Computers

You can switch between the connected computers using two methods:

• Front Panel Button: Press the corresponding PC1, PC2, or PC3 button on the front of the KVM switch to select the desired computer.
• Wired Remote Control: Press the button on the wired remote control to cycle through the connected computers.

LED indicators on the KVM switch will illuminate to show which computer is currently active.

Display Modes

When using a Windows laptop, you can select between extended screen mode or mirror mode by pressing "Windows + P".

Note for Apple M1/M2/M3 Users:

• Apple M1/M2 chips typically support only single-screen output.
• MacBook Pro (M3) models may not output images through both USB-C and HDMI ports simultaneously; only one image output may be available.

EDID Emulation

The KVM switch supports EDID lock functionality. This feature automatically adjusts monitor settings for optimal resolution and refresh rate, ensuring consistent image quality. When switching between computers, the original window order and desktop layout will be preserved. You can enable or disable the EDID function using the switch on the front panel.

Laptop Charging (PD)

When your laptop is connected via the USB-C port to the KVM switch, it will receive up to 85W of power for charging. Ensure you use a 100W Power Delivery (PD) charger connected to the KVM switch for optimal charging efficiency.
