Primarily, this is caused when the monitor doesn’t support the signals sent by the video adapters. Moreover, it can also be due to corrupted device drivers or hardware malfunctions.Generally, you get an additional message after encountering this message, like asking you to change the refresh rate or resolution. Thus, fixing this problem shouldn’t be burdensome.
Causes: “Input Signal Out of Range” on Monitor
How to Fix “Input Signal Out of Range” Monitor Error?
If you didn’t tweak any settings or overclocked the refresh rate but still see the “Input Signal Out of Range,” we recommend restarting your PC or console to see if this fixes the problem. However, modern monitors are now capable of supporting a plethora of screen resolutions and refresh rates. Nonetheless, this is also limited, and when the device you’re connected to sends signals of higher resolution or refresh rate, the message “Input Signal Out of Range” pops up. Basically, this is an indication that your monitor cannot handle these signals. Thus, you need to set your display settings to the display device’s highest supported resolution and refresh rate.

Fix Corrupted Display or Monitor Drivers
If you’re repeatedly getting an error message after changing the screen resolution and refresh rate, there are probably issues with the display or monitor driver.If there are bugs or other errors, they might interfere with the input signals. Thus, it’s necessary to check and update the device drivers regularly. If that didn’t help, you could try reinstalling them:If updating or reinstalling the corrupted adapters doesn’t solve your problem, we recommend installing the latest ones from the manufacturer’s website. Here’s a complete guide on how to install the monitor drivers manually.
Boot PC in Low-Resolution Video Mode
If your PC didn’t start in safe mode, you could try booting it in low-resolution video mode, also referred to as the VGA mode.
