Operating Instructions
The VPFET KVM switch offers two methods for switching between connected computers:

Image: A visual guide demonstrating the two primary methods for switching between connected computers: via the remote control and directly using the KVM switch's front panel buttons.
1. Button Switching:
Press the corresponding PC1, PC2, PC3, or PC4 button on the front panel of the KVM switch to select the desired computer. The LED indicator next to the button will illuminate to show the active PC.
2. Infrared (IR) Remote Control:
Use the included IR remote control to switch between computers. Point the remote at the IR receiver connected to the KVM switch and press the button corresponding to the desired PC (1, 2, 3, or 4). The LED indicator on the KVM switch will update to reflect the active PC.
Note: Hotkey switching is not supported by this KVM switch.
Resolution and Performance Notes
This KVM switch supports high resolutions and refresh rates. To achieve optimal performance, consider the following:

Image: A visual representation highlighting the KVM switch's capability to support high resolutions such as 8K@60Hz and 4K@144Hz, compatible with HDMI 2.1 and DisplayPort 1.4 standards.
- Maximum Resolution: Supports up to 8K@60Hz and 4K@144Hz. It is backward compatible with lower resolutions.
- System Requirements: For 8K resolution, ensure your source device (PC), monitors, and all connecting cables (HDMI and DisplayPort) support 8K.
- Cable Quality: The quality and length of your HDMI and DisplayPort cables significantly impact video transmission quality. Shorter, high-quality cables are recommended for optimal performance, especially at higher resolutions and refresh rates.
USB 3.0 Functionality
The KVM switch includes four USB 3.0 ports for sharing peripherals between your connected computers.

- Data Transfer Speed: USB 3.0 ports support data transfer speeds up to 5 Gbit/s.
- Peripheral Compatibility: Connect keyboards, mice, USB flash drives, printers, and other USB devices.
- Connection Requirement: Ensure each computer is connected to the KVM switch via its dedicated USB 3.0 A-A cable. If a computer is not connected via USB, its USB peripherals will not be recognized by the KVM switch.
- Bluetooth Devices: Bluetooth mice and other Bluetooth peripherals are not supported directly through the KVM's USB ports.
Troubleshooting
If you encounter issues, refer to the following common troubleshooting steps:
- No Display on Monitors:
- Verify all HDMI and DisplayPort cables are securely connected between the computers, KVM switch, and monitors.
- Ensure the KVM switch is powered on and the correct PC input is selected.
- Check if your computers and monitors are powered on and functioning correctly independently.
- Confirm that your computer's graphics card supports the number of monitors and the resolutions you are attempting to use.
- Try using shorter, high-quality cables, especially for high-resolution setups.
- USB Peripherals Not Working:
- Ensure each computer is connected to the KVM switch via its dedicated USB 3.0 A-A cable.
- Try connecting the USB peripheral directly to the computer to confirm it is functional.
- Restart the KVM switch and the connected computers.
- Note that Bluetooth mice are not supported.
- Intermittent Display or Flickering:
- This can often be caused by long or low-quality HDMI/DisplayPort cables, especially at high resolutions. Replace with certified high-speed cables.
- Ensure all connections are tight.
- Reduce the resolution or refresh rate to see if the issue persists.
- Switching Delay:
- A brief delay during switching is normal as the KVM re-establishes connections with the new source. This is more noticeable with higher resolutions and multiple monitors.
- Remote Control Not Working:
- Ensure the IR receiver is properly plugged into the KVM switch's IR port.
- Check the battery in the remote control.
- Ensure there are no obstructions between the remote and the IR receiver.
