5.1 Switching Between Computers

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

• Front Panel Buttons: Press the corresponding input button on the front panel to switch to a specific computer.
• Hotkey Switching: Use predefined keyboard hotkeys to switch inputs. Refer to the detailed user manual for specific hotkey combinations.
• IR Remote Control: Use the included IR remote control to select inputs. (Requires AAA batteries, not included).

5.2 EDID Emulation

The KVM switch incorporates EDID emulators on each input port. This feature ensures that your computers always receive correct display information, preventing issues such as desktop icon rearrangement, screen flickering, or window clutter when switching between inputs. The EDID emulator maintains consistent display settings for each connected PC.

5.3 Independent Audio & USB Focus Lock

This feature provides granular control over KVM, audio, and USB focus. You can lock the audio or USB focus to maintain the current audio playback or USB device connection while switching only the video display to another computer. This is useful for scenarios where you need to listen to audio from one PC while working on another, or keep a USB device connected to a specific PC.

5.4 KVM System Lock

The KVM switch includes a lock function to enhance privacy and security. Pressing the LOCK button can turn off all displays, pause audio, and dim the LCD screen. To unlock, press the LOCK button again to light up the LCD screen, then enter your PIN.

6. Maintenance

To ensure optimal performance and longevity of your TESmart KVM Switch, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the exterior of the KVM switch. Avoid using liquid cleaners or aerosols, which may damage the device.
• Ventilation: Ensure the KVM switch is placed in a well-ventilated area to prevent overheating. Do not block any ventilation openings.
• Cable Management: Organize cables neatly to prevent strain on ports and accidental disconnections.
• Power Supply: Use only the original power adapter provided with the KVM switch.

7. Troubleshooting

If you encounter issues with your KVM switch, refer to the following common problems and solutions:

7.1 No Display or Incorrect Resolution

• Check Cables: Ensure all HDMI and DisplayPort cables are securely connected to both the KVM switch and your monitors/computers.
• Verify Input Selection: Confirm that the KVM switch is set to the correct input for the desired computer.
• Power Cycle: Power off the KVM switch, monitors, and computers. Then, power on the KVM switch, followed by the monitors, and finally the computers.
• EDID Issues: If the display resolution or arrangement is incorrect after switching, try switching to another input and then back. The EDID emulation should help maintain settings, but occasional resets can resolve temporary glitches.
• Cable Quality: Ensure you are using high-quality HDMI and DisplayPort cables that support the desired resolution and refresh rate (e.g., 4K@60Hz, 2K@144Hz).

7.2 Keyboard or Mouse Not Responding

• Check Connections: Ensure the keyboard and mouse are connected to the dedicated K/M USB 1.1 ports on the KVM switch.
• USB-B Cables: Verify that the USB-B cables connecting the computers to the KVM switch are properly connected.
• Try Different Ports: If using a gaming or multimedia keyboard/mouse, try connecting them to the USB 3.0 ports instead of the dedicated K/M ports, as these may require direct USB passthrough.
• Power Cycle: Perform a power cycle of the KVM switch and affected computer.

7.3 Slow Switching Time

• Switching between inputs on a KVM with multiple high-resolution displays can take a few seconds as the system re-establishes connections. This is normal behavior for digital KVMs.
• Ensure all video cables are of sufficient quality and length. Longer or lower-quality cables can sometimes increase switching time.

7.4 Fan Noise

• The KVM switch may have a fan for cooling. Check the device settings for fan control options. Some models allow setting the fan to run only when needed, rather than continuously at high speed.

7.5 Beeping Sound During Switching

• Some KVM models emit an audible beep to confirm a successful switch. Refer to the full user manual for information on disabling this sound, if available.
