What happens when you receive an input signal out of range error? Is there any way that you can fix it on your monitor?

Why Does Your Monitor Keep Having an Input Signal Out of Range Error?

If your monitor is giving you the error message, it could be because of issues with the input signal.

Your monitor refreshes the display depending on the instructions it gets from your video card. The process follows a frequency that enables your monitor to offer you real-time visualization.

For instance, a 60 Hz refresh rate means the monitor refreshes the display 60 times per second. If you set the frequency higher than the monitor's capabilities, you'll receive an annoying error code.

Additionally, the input signal error shows that the combination of frame rate and monitor resolution results in a faster pixel clock rate than your screen's capability. To deal with the issue, you will have to reduce the frame rate or adjust the screen resolution.

The input signal out of range error message comes with additional information. Your screen will display two modes, including the current mode and the mode you should reach. The information on the screen will have two parameters, including horizontal and vertical.

It will also include the aspect ratio or format you require to adjust screen resolution.

What Are the Common Causes of Input Signal Out of Range Error?

As mentioned earlier, the error occurs due to an incompatibility between the video signal and the screen capabilities. Using an old graphics card with a new monitor can cause signal input error.

The incompatibility involves the refresh rate of the monitor and the frame rate. If the monitor refreshes the display at a frequency higher than it can handle, you'll receive the error.

Some people think you can skip the error or deal with it with just some clicks. However, the error indicates a significant underlying issue between your monitor and the graphics card. You'll need to deal with the underlying issue to fix the input signal error.

Update the Monitor’s Drivers

If rebooting the computer in safe mode and adjusting the resolution doesn't solve the problem, you can update the drivers.

Here, we'll update the display adapter. The process can include updating the native graphics card or the dedicated driver. The update will also happen in safe mode to ensure no settings are on and only essential systems are running.

You can download the drivers from the official website and then manually install them on your computer.

Use the following steps to update the drivers:

  • 1. As you reboot your system, press F8 to enter the safe mode
  • 2. On the bottom left side of the monitor, right-click on the Windows logo
  • 3. Select the option for the Device Manager

If the input signal out of range error persists, you may have a hardware malfunction. The monitor or video card may have a problem. You can try to check if your monitor is working.

To check if the video card or your monitor has a problem, you can try the following troubleshooting method.

  • First, you can borrow another computer and connect your computer monitor. If the monitor works using the new computer, your computer's video card may be malfunctioning.
  • Alternatively, get a working monitor and connect it to your computer. If the new monitor works with your computer, it means your monitor is faulty, and you need to replace it. On the other hand, if the new monitor doesn't work, your computer may have a bad video card.
