Troubleshooting “Input Signal Out of Range” Error on Windows 11 Monitors

Encountering display issues can be a frustrating experience, particularly when error messages like “Input Signal Out of Range” appear unexpectedly. This problem typically indicates a mismatch between your computer’s output resolution or refresh rate and what your monitor can handle, often caused by driver problems, incorrect display settings, or hardware conflicts.

Understanding the Issue

The “Input Signal Out of Range” message generally appears when your graphics card is sending a signal that exceeds your monitor’s supported parameters, such as resolution or refresh rate. Users running Windows 11 have reported this issue, especially after driver updates or reinstalls, which can reset display settings or introduce incompatibilities.

Common Causes

• Incorrect display resolution or refresh rate settings
