4. Setup Instructions

Follow these steps to connect your AOOCOO KVM Switch:

1. Power Off Devices: Ensure all computers and monitors are powered off before making connections.
2. Connect Monitors to KVM: Connect your two monitors to the KVM switch's OUT A and OUT B HDMI ports using HDMI 2.0 cables.
3. Connect Computers to KVM (Video): For each computer, connect its two HDMI output ports to the corresponding HDMI input ports on the KVM switch (e.g., PC1's HDMI outputs to INPUT A1 and INPUT B1; PC2's HDMI outputs to INPUT A2 and INPUT B2).
   Important: Each computer must have two HDMI output ports and support extended display for dual monitor functionality. The switch is not compatible with DP/DVI/VGA to HDMI converters. If your computer only supports a single display, this product cannot provide dual display functionality.
4. Connect Computers to KVM (USB): Connect the USB 3.0 cables from each computer's USB port to the corresponding USB 3.0 input ports on the KVM switch (e.g., PC1's USB to USB3.0 (PC1); PC2's USB to USB3.0 (PC2)).
5. Connect Peripherals: Plug your keyboard, mouse, and other USB devices into the USB 3.0 ports on the front panel of the KVM switch.
6. Optional Power: If connecting high-power USB devices (e.g., docking stations), connect a DC 5V power supply (not included) to the DC/5V port on the KVM switch.
7. Power On: Power on your computers and monitors.
8. Configure Display Settings: After connecting, you may need to set the screen output mode on your computer. For Windows, press Windows + P and select your desired display mode (e.g., Extend or Duplicate) in the pop-up window.

5. Operating Instructions

5.1. Switching Between Computers

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

• Front Panel Button: Press the "SELECT" button on the front panel of the KVM switch to switch to the next active computer.
• Wired Controller: Use the included wired controller to switch between computers. This is convenient if the KVM switch unit is not easily accessible.

Figure 5.1: Two switching methods.

5.2. LED Indicators

The two-color LED indicator on the KVM switch will illuminate to show which computer is currently active.

6. Display Modes

The KVM switch supports two primary display modes for your dual monitor setup:

• Extended Display Mode: Outputs two different screens, allowing you to extend your desktop across both monitors.
• Copy Display Mode (Mirror Mode): Outputs two identical screens, duplicating the content on both monitors.

Figure 6.1: Extended vs. Copy Display Modes.

7. USB 3.0 Ports

The KVM switch is equipped with four USB 3.0 ports, enabling two computers to share various USB 3.0 devices. USB 3.0 offers a faster data transfer speed of up to 5Gbps, which is significantly faster than USB 2.0's 480Mbps. It is also backward compatible with USB 2.0/1.1 devices.

8. EDID Simulation

This KVM switch features EDID (Extended Display Identification Data) emulation. It stores the resolution and refresh rate of your display, ensuring that connected PCs always have correct display information. This prevents issues like scrambled desktop icons or resolution changes when switching between computers, as the system believes the monitor is always connected.

9. Compatibility

The AOOCOO KVM Switch is driver-free and plug-and-play. It is compatible with a wide range of operating systems, including Windows 10/8/8.1/7/Vista/XP, Mac OS, and Linux.

10. Important Notes & Considerations

• The KVM switch requires each connected computer to have two HDMI output ports and support extended display.
• It supports USB-C to HDMI converters but is not compatible with DP/DVI/VGA to HDMI converters.
• If your computer only supports a single display, this product cannot help you achieve dual display functionality.
• For 4K resolution, ensure you use HDMI 2.0 cables and that both your computers and monitors support 4K.
• The switcher typically does not require extra power for normal operation as USB ports can provide power. However, if a high-power docking station or other high-power USB devices are connected, additional power via the DC 5V port may be necessary.

11. Troubleshooting

• No Display/Incorrect Resolution:
  • Verify that each computer has two HDMI output ports and is configured for extended display.
  • Ensure all HDMI cables are HDMI 2.0 compliant, especially for 4K resolution.
  • Check that all connections are secure and correctly plugged into the designated input/output ports on the KVM switch.
  • Try restarting the computers and monitors.
  • Confirm your monitors and computers support the desired resolution (e.g., 4K@60Hz).
• Keyboard/Mouse Not Responding:
  • Ensure the USB 3.0 cables from each computer are securely connected to the KVM switch.
  • Try connecting the keyboard and mouse directly to the computer to confirm they are functioning.
  • If using wireless peripherals, ensure their receivers are plugged into the KVM's USB 3.0 ports.
• Display Issues After Switching:
  • The EDID simulation feature should prevent most display issues. If problems persist, ensure your computer's display settings are correctly configured for extended or duplicate mode.
  • Try pressing Windows + P on the keyboard and re-selecting the output mode.
• No Power/Intermittent Power:
  • If using high-power USB devices, ensure an external DC 5V power supply is connected to the KVM switch.
  • Check all power connections.
