The experience of sitting down at your computer, ready to work or play, and being greeted with the dreaded “Input Signal Not Found” message on your HP monitor can be frustrating and perplexing. This error message typically appears when your monitor is unable to detect a valid input source from your computer or other connected devices. However, fear not, for this blog post is here to guide you through the troubleshooting process and help you resolve the “Input Signal Not Found” issue on your HP monitor.
Understanding the “Input Signal Not Found” Error
Before diving into the troubleshooting steps, it’s essential to understand the potential causes of this error. The “Input Signal Not Found” message occurs when the monitor fails to detect an active and stable input signal from the connected source, such as your computer, gaming console, or other devices. Several factors can contribute to this issue:
- Faulty or Loose Cable Connections: Loose, damaged, or improperly connected cables (VGA, HDMI, DVI, DisplayPort) can disrupt the signal transmission between your device and the monitor.
- Incorrect Input Source Selection: If you have multiple input sources (e.g., multiple computers, gaming consoles), the monitor may be set to the wrong input source.
- Resolution or Refresh Rate Mismatch: Incompatibility between the resolution and refresh rate settings of your computer’s graphics card and the monitor can lead to signal problems.
- Monitor Sleep Mode: Some monitors may enter a sleep mode when they don’t detect an input signal for a certain period, which can trigger the error message.
- Graphics Card or Driver Issues: Problems with your computer’s graphics card or outdated graphics drivers can affect the signal transmission.
- Hardware Faults: Rarely, hardware faults in the monitor itself, such as a malfunctioning input port or internal component, may be the cause.
Now that we’ve identified potential culprits let’s proceed with troubleshooting and solutions to resolve the “Input Signal Not Found” issue on your HP monitor.
Check Cable Connections
- Ensure that all cables connecting your computer or device to the monitor are securely plugged in at both ends. Pay attention to cable damage and replace any faulty cables.
Verify Input Source
- Use the monitor’s on-screen menu (accessible via buttons or a remote control, depending on your monitor model) to check and select the correct input source. Make sure it matches the port where your device is connected (e.g., HDMI, DisplayPort).
- Turn off both your computer and monitor.
- Disconnect all cables from your monitor.
- Wait for a few minutes.
- Reconnect the cables and power on your monitor, followed by your computer.
Adjust Resolution and Refresh Rate
- Boot your computer in Safe Mode (if possible) to access basic display settings.
- Lower the resolution and refresh rate settings to values supported by your monitor.
- Restart your computer and check if the error is resolved.
Test with Another Device
- If you have access to another device (e.g., laptop, gaming console), connect it to your monitor using the same cables to check if the error persists. This can help identify whether the issue is with the monitor or the original device.

Graphics Card and Driver Update
- Ensure that your computer’s graphics card is functioning correctly. If you have a dedicated graphics card, reseat it firmly in its slot.
- Update your graphics card drivers to the latest version from the manufacturer’s website.
Monitor Sleep Mode
- Access your monitor’s settings menu and disable any power-saving or sleep mode features, which may be prematurely turning off the display.
- If none of the above steps resolve the issue, consider performing a factory reset on your monitor through its settings menu. Refer to the monitor’s user manual for specific instructions.
Test with Another Monitor
- To confirm whether the issue is with your monitor or your computer/device, connect your computer/device to a different monitor using the same cables. If the new monitor works, the problem likely lies with your HP monitor.
Contact HP Support
- If all else fails, and you suspect a hardware issue with your HP monitor, it’s advisable to contact HP Support or visit an authorized service center for further diagnosis and potential repair or replacement.
Preventing Future “Input Signal Not Found” Issues
To minimize the chances of encountering this error in the future, consider implementing these preventive measures:
- Regular Cable Maintenance: Periodically inspect and secure cable connections to prevent loose or damaged cables from causing signal problems.
- Keep Graphics Drivers Updated: Ensure your computer’s graphics drivers are up to date to maintain compatibility with your monitor.
- Use Quality Cables: Invest in high-quality cables for connecting your devices to the monitor, as they are less prone to signal interference.
- Monitor Power Settings: Adjust your monitor’s power settings to avoid it entering sleep mode too quickly when there’s no input signal.
- Monitor Firmware Updates: Check for firmware updates for your HP monitor, as these updates may include fixes for potential signal issues.
Encountering the “Input Signal Not Found” error on your HP monitor can be frustrating, but with systematic troubleshooting and the right solutions, you can often resolve the issue and enjoy uninterrupted computing or gaming experiences. Remember to check cable connections, select the correct input source, and adjust resolution and refresh rate settings to match your monitor’s capabilities.
If the issue persists despite your best efforts, consider testing with another device or monitor to pinpoint the source of the problem. And if you suspect a hardware issue with your HP monitor, don’t hesitate to reach out to HP Support for professional assistance.
