- Connect Computers to KVM Input: For each computer (PC1, PC2, PC3):
- Connect two DisplayPort cables from the computer's graphics card to the KVM's DP A and DP B input ports for that PC.
- Connect one HDMI cable from the computer's graphics card to the KVM's HDMI C input port for that PC.
- Connect one USB 3.0 A-to-A cable from a USB 3.0 port on your computer to the corresponding USB 3.0 input port on the KVM for that PC.
Important: Each PC must have 2 DisplayPort, 1 HDMI, and 1 USB 3.0 port available for full functionality.
- Connect Peripherals: Connect your USB keyboard, mouse, and any other USB 3.0 devices to the USB 3.0 ports on the front panel of the KVM switch.
- Connect IR Extender (Optional): If using the IR remote control from a distance, connect the IR extend cable to the 'EXT IR' port on the KVM switch.
- Power On KVM: Connect the DC 12V power adapter to the KVM switch and plug it into a power outlet. Turn on the KVM switch using the ON/OFF button.
- Power On Computers and Monitors: Power on your monitors and then your computers.
4.3 Important Notes
- Use high-quality 8K@60Hz or 4K@120Hz DisplayPort and HDMI cables for optimal performance.
