4. Setup Instructions
- Power Off All Devices: Ensure all computers and monitors are powered off before beginning the connection process.
- Connect Monitors to KVM: Connect your three monitors to the KVM Switch's "OUT A", "OUT B", and "OUT C" ports using appropriate HDMI and DisplayPort cables.
- Connect Computers to KVM: For each computer (PC1, PC2, PC3, PC4):
- Connect two HDMI outputs from your computer to the corresponding HDMI input ports on the KVM (e.g., PC1's HDMI outputs to KVM's PC1 HDMI inputs).
- Connect one DisplayPort output from your computer to the corresponding DisplayPort input port on the KVM (e.g., PC1's DisplayPort output to KVM's PC1 DisplayPort input).
- Connect one USB 3.0 cable from your computer's USB port to the corresponding USB 3.0 input port on the KVM (e.g., PC1's USB to KVM's PC1 USB 3.0 input).
Important: Ensure all video and USB cables from a single computer are connected to the same PC input group on the KVM (e.g., all cables for PC1 go to the PC1 input section).
- Connect Peripherals: Connect your keyboard, mouse, and other USB 3.0 devices (e.g., webcam, hard drive, printer) to the USB 3.0 ports on the front panel of the KVM Switch.
- Connect Wired Remote (Optional): Plug the wired remote control into the dedicated port on the front panel.
- Power On KVM: Connect the 12V power adapter to the KVM Switch and plug it into a power outlet. Turn on the KVM using the power button.
- Power On Computers and Monitors: Power on your computers and monitors. The KVM will automatically detect the active input.
5. Operating Instructions
You can switch between connected computers using two methods:
Method 1: Front Panel Buttons
Press the corresponding PC selection button (PC1, PC2, PC3, or PC4) on the front panel of the KVM Switch to switch to the desired computer. An LED indicator will illuminate to show the active computer.
Method 2: Wired Remote Control
Press the button on the wired remote control to cycle through the connected computers. Each press will switch to the next active PC in sequence.

Switching between computers using the front panel button or the wired remote control.
6. Display Modes
The KVM switch supports both Mirror and Extended display modes. You can typically configure these modes through your computer's operating system display settings (e.g., Windows + P shortcut on Windows).
- Mirror Mode: Displays the same content on all three monitors.
- Extended Mode: Extends your desktop across all three monitors, allowing for three different screens.

7. EDID Emulation
The KVM Switch features EDID emulation on its HDMI input ports. This function allows the KVM to store and simulate the display's EDID (Extended Display Identification Data) to the connected computers. This ensures that your computers always detect the correct display resolution and refresh rate, preventing display issues when switching between sources or when a computer is not actively selected.
Note: DisplayPort (DP) inputs do not support EDID emulation.

8. USB 3.0 Data Transfer
The integrated USB 3.0 ports support ultra-fast data transfer speeds of up to 5Gbps, which is significantly faster than USB 2.0. This allows for quick and efficient use of connected USB peripherals.

9. Troubleshooting
If you encounter issues with your KVM Switch, please refer to the following common problems and solutions:
- No Display on Monitors:
- Ensure all HDMI and DisplayPort cables are securely connected between the computers, KVM, and monitors.
- Verify that the KVM Switch is powered on and the correct PC input is selected.
- Check if the monitors are powered on and set to the correct input source.
- Try restarting the KVM Switch and then the computers.
- Ensure your graphics card drivers are up to date.
- Keyboard/Mouse Not Working:
- Ensure the USB 3.0 cables are properly connected from the computers to the KVM.
- Try connecting the keyboard and mouse to different USB 3.0 ports on the KVM.
- Some specialized gaming keyboards/mice may require direct connection to the computer or specific drivers.
- Restart the KVM Switch.
- Resolution or Refresh Rate Issues:
- Ensure your cables (HDMI 2.0, DisplayPort 1.2 or higher) support the desired resolution and refresh rate (e.g., 4K@60Hz).
- Verify your computer's display settings are configured for the correct resolution and refresh rate.
- Remember that DisplayPort inputs do not support EDID emulation, which might affect display detection on DP connections.
- Intermittent Connectivity:
- Check all cable connections for looseness.
- Ensure the power adapter is securely connected and providing stable power.
- Avoid using excessively long or low-quality cables, which can degrade signal integrity.
