3. Connect USB Inputs: Connect the USB 3.0 output of each computer/source device to the corresponding USB3.0-PC port (USB3.0-PC1 to USB3.0-PC4) on the KVM switch using the provided USB 3.0 cables. สำคัญ: Connect the USB HDMI cable first to wake up the USB switch (allow approximately 20 seconds for recognition).

4. เชื่อมต่อจอภาพ: Connect your HDMI monitor to the HDMI OUT port on the KVM switch.

5. เชื่อมต่อคีย์บอร์ดและเมาส์: Connect your USB keyboard to the USB2 port and your USB mouse to the USB1 port on the front panel of the KVM switch. For optimal performance, ensure the mouse is connected to USB1 and keyboard to USB2.

Image: Key considerations for setup, including using HDMI 2.0 standard cables under 3 meters, setting video format to AUTO mode for PS5/Laptop/PC, and ensuring display device compatibility.

หมายเหตุสำคัญ:

• Please use less than 3-meter AWG26 HDMI 2.0 Standard cables for all HDMI ports.
• The KVM switch does not support down-scaling a 4K source to a 1080p display.
• Set your PS5/Laptop/PC video format to AUTO mode. The KVM switch will copy the EDID of the TV or monitor automatically.
• Ensure your HDMI source and display devices support each other without the KVM switch connected first to rule out compatibility issues.
