The Input not supported error commonly appears when your monitor’s and PC settings have compatibility issues. This leads to an inability of the latter to process the signal, which shows the message on the screen.
Here are the most frequent causes that could be at play:
- Outdated or faulty drivers: Drivers link your operating system and hardware. Corrupted ones can result in numerous issues, such as this one or other black screen issues.
- Hardware issues: Damaged cables or ports can hinder the connection.
- Display settings: If the resolution/refresh rate doesn’t match or is not supported by the device’s specs, the result will most likely be the said error.
Now that you know what are the most common scenarios behind it, let’s learn how to fix them:
How do I fix input not supported on my monitor?
Before resorting to our tested solutions, you should:
- Determine the source of your issue: Switching on another display might help identify the problem’s origin.
- Ensure all cables work and are properly plugged in: Try unplugging and plugging back in your wires or even switching to a different cable. Keep in mind that older cables might not support higher resolutions.
- Restart your PC: Sometimes, a simple fix like a reboot solves the entire issue. Try it; it might help.
1. Change your display resolution
- Run your device in Safe mode.
- Right-click on an empty area on your desktop and choose Display settings.
- Navigate to Display resolution and choose a low one.
- Work your way up until you find one that best suits your needs and specs.
- Restart your computer.
Due to your screen being black with the error, you can access your display settings the standard way. This necessitates starting up Windows in Safe mode.
Once in safe mode, your OS will employ a basic display driver and allow customization without showing the error. Then, you can adjust the resolution to match the recommended specs and solve your problem.
2. Modify your monitor’s settings
- Right-click on an empty area on your desktop and open Display settings.
- Choose the Advanced display option.
- Navigate to Display adapter properties.
- Go to the Monitor tab.
- Lower the Screen refresh rate and click Apply.
Refresh rate relates to the number of image refreshes on the screen per second. High RTs are sometimes more than your monitor can handle, which could lead to encountering the Input not supported error. Try reducing the refresh rate to resolve your issue.
