When connecting an external monitor to a Windows PC, you may encounter an "Input Signal Out of Range" error. This error usually occurs if you have a high refresh rate monitor connected to a lower end graphics device. Also, the lack of support for higher resolutions on the monitor or graphics card is another common cause of this error.

To fix this error, you can change the screen resolution to match the resolution of your video card. In addition, reducing the screen refresh rate to the standard 60Hz mark can help you fix the error. Here's how to do that.

1. Change the screen resolution to Windows recommended settings

One way to fix the "Input Signal Out of Range" error is to set the screen resolution recommended by Windows. Usually, the error message shows the recommended screen resolution, making it easier to define and configure display settings. Otherwise, Windows may automatically detect and suggest it in the Settings app.

On a single monitor setup with no video signal, you'll need to boot into Safe Mode to see your display settings. So, explore TipsMake's guide on how to boot into Safe Mode on Windows and then proceed with the steps below.

In the System tab , scroll down and click Display.
Next, scroll down to the Scale & layout section .
Click the Display resolution drop-down menu and select the Recommended option .

After you set the correct screen resolution, your external monitor will start receiving the signal and the error will be fixed.

To fix this error, try reducing the screen refresh rate to the standard 60Hz. Once the error is fixed, you can use the options to find a higher refresh rate profile without the error.

Again, perform these steps in Safe Mode if you have a single monitor setup.
