How to Fix the “Input Signal Out of Range” Error on Your Monitor
The “Input Signal Out of Range” or “Monitor Input Signal Not Found” errors can be frustrating, often indicating a mismatch between your computer’s display settings and your monitor’s capabilities. Fortunately, resolving these issues can usually be done by adjusting your PC’s resolution or refresh rate. This guide will walk you through straightforward steps applicable for both Windows 10 and Windows 11, ensuring that your monitor functions correctly with your desktop or laptop.
Step 1: Boot into Safe Mode
If your monitor displays an error and prevents access to the desktop, start your PC in Safe Mode. Safe Mode loads a minimal set of drivers which often resolves display issues allowing for adjustments to settings. To enter Safe Mode, follow these steps:
- Restart your computer.
- As your computer boots, repeatedly press the F8 key until the Advanced Boot Options menu appears.
- Select Safe Mode from the list using your keyboard arrow keys.
Once in Safe Mode, you will have a basic interface and can start adjusting the display settings.
Step 2: Adjust Screen Resolution
Once in Safe Mode, it’s essential to ensure that your screen resolution is compatible with your monitor. Follow these steps:
- Right-click on the desktop and select Display settings.
- Scroll down to the Resolution section.
- Use the dropdown menu to set the resolution to a value that your monitor can support, typically the native resolution. For most monitors, 1920 x 1080 is a good starting point.
- Click Keep changes or simply wait for the changes to take effect automatically.
After adjusting the resolution, check if the monitor displays correctly. If the issue persists, proceed to adjusting the refresh rate.
Step 3: Change Refresh Rate Settings
Another possible cause of the “Input Signal Out of Range” error is an incompatible refresh rate. Refresh rate refers to how often the image on your screen is updated per second, typically measured in Hertz (Hz). Here’s how to adjust it:
- In the Display settings, scroll down and click on Advanced display settings.
- Active your monitor from the dropdown.
- Select Display adapter properties.
- In the new window, click on the Monitor tab.
- Under Monitor Settings, find the Screen refresh rate option and select a value supported by your monitor, usually 60Hz or 75Hz.
- Click OK to apply the changes.
Test again to see if your monitor is functioning correctly. If it still doesn’t work, you may need to explore further troubleshooting options.
Step 4: Update Graphics Drivers
Outdated or corrupted graphics drivers can lead to display issues as well. It’s important to ensure your graphics drivers are up to date. Here’s how to check and update them:
- Press Windows + X and select Device Manager.
- Expand the Display adapters section.
- Right-click on your graphics card and select Update driver.
- Choose Search automatically for updated driver software and follow the on-screen instructions.
Reboot your computer after the update and check if the issue persists.
Step 5: Reset the Monitor
If none of the above steps work, resetting your monitor to factory settings can help. This step can be crucial as it returns display settings to defaults:
- Access your monitor’s on-screen display (OSD) menu using the buttons on the monitor itself.
- Navigate to settings and look for an option like “Factory Reset” or “Reset to Default.”
- Confirm the action to reset your monitor settings.
This process varies by manufacturer, so consult your monitor’s user manual if unsure.
Extra Tips & Common Issues
When encountering the “Input Signal Out of Range” error, always first verify the physical connections between your computer and monitor. Ensure the cables are securely plugged in and undamaged. Additionally, if you’re using an adapter (like HDMI to DVI), consider testing with a direct connection if possible.
Conclusion
Resolving the “Input Signal Out of Range” error typically involves adjusting the settings on your computer to match those supported by your monitor. By following these steps, you will likely fix the issue and have your monitor functioning correctly again. If problems persist, consider reaching out for professional technical support or consulting your monitor’s support page for specific recommendations.
