Troubleshooting 'Input Signal Out of Range' Error: Monitor Settings Fix

Table of Contents

Encountering an ‘Input Signal Out of Range, Change settings to [resolution]’ or ‘Change Mode to [resolution]’ error message on your monitor can be frustrating. This issue prevents your display from showing a proper image because the signal it’s receiving from your computer’s graphics card is outside the range of resolutions and refresh rates the monitor supports. While not an everyday problem, it can occur on Windows systems due to several factors, most notably a mismatch between the graphics output settings and the monitor’s capabilities.

This error message typically includes the specific resolution and refresh rate that the monitor does support, guiding you toward the necessary correction. The problem arises when the computer attempts to send a signal, perhaps 1920x1080 at 120Hz, but the monitor’s maximum supported output is only 1920x1080 at 60Hz, or perhaps a lower resolution entirely like 1366x768. The graphics card’s capabilities might exceed the display’s, and if the settings on the computer are configured to utilize those higher capabilities, the monitor simply cannot process the signal effectively, resulting in the “out of range” error.

There are primarily two scenarios you might face when this error occurs. In the less severe situation, your monitor might display the error message but still occasionally show content or flicker, allowing some limited interaction with the computer. The more challenging scenario is when the monitor is completely unusable, displaying only the error message or remaining black, making it impossible to navigate the operating system normally. The approach to fixing the issue depends significantly on which of these situations you are experiencing.

If you can still partially use your computer or have a multi-monitor setup where at least one display is functioning correctly, the troubleshooting steps are relatively straightforward. However, if the problematic monitor is your only display and it’s completely blank or stuck on the error, you will need to resort to more advanced methods like booting into Safe Mode or utilizing a Windows installation media to gain access to display settings. Fortunately, the underlying fix usually involves adjusting the display configuration back to a supported mode.

To resolve the ‘Input Signal Out of Range, Change settings’ monitor error, the most effective solutions involve adjusting the display resolution and ensuring your graphics drivers are functioning correctly. These steps aim to reset the display output to a configuration that your monitor is known to support.

Here are the primary methods to fix this issue:

1. Change the display resolution, often requiring the use of Safe Mode.
2. Address potential problems with your graphics driver by reinstalling it.

Let’s delve into each of these steps to understand how to implement them effectively.

Fix Input Signal Out of Range, Change settings Monitor error¶

Correcting the display configuration is paramount when facing the ‘Input Signal Out of Range’ error. This typically involves accessing the display settings within Windows and selecting a resolution and refresh rate that are compatible with your monitor. The difficulty lies in accessing these settings when the primary display is not functioning correctly.

The techniques used to change the resolution will vary based on whether you can see anything on the screen or if you have an alternative display available. Regardless of the scenario, the goal is to set the resolution to the monitor’s native resolution or a lower, universally compatible resolution like 800x600 or 1024x768, and often a standard refresh rate like 60Hz, which most monitors support.

1] Change resolution in Safe Mode¶

Changing the display resolution is the most direct method to fix an ‘Input Signal Out of Range’ error, especially when it’s caused by a resolution or refresh rate mismatch. Safe Mode is a diagnostic mode in Windows that starts the computer with a minimal set of drivers and services, including a basic display driver that typically operates at a low, compatible resolution (like 800x600 or 1024x768) and standard refresh rate (usually 60Hz). This minimal configuration is often viewable by almost any monitor, providing a window to fix the display settings.

The approach to changing resolution differs based on your monitor setup:

• Dual Monitor Setup (One Monitor Working): If you have a multi-monitor configuration and the error appears on one secondary monitor while your primary monitor is working correctly, you do not need to enter Safe Mode. You can simply use your working monitor to access the display settings for the problematic one.

  • Begin by pressing Win + I on your keyboard to quickly open the Windows Settings application.
  • In the Settings window, navigate to the System category, and then select Display from the left-hand menu.
  • Here, you will see a diagram representing your connected monitors. Click on the monitor that is showing the error message to select it. Make sure it is the active monitor you are configuring.
  • Scroll down within the Display settings for the selected monitor until you find the Display resolution section.
  • Click the drop-down list under Display resolution and choose a resolution that you know is supported by the problematic monitor. It’s often best to select the recommended resolution, which is usually the monitor’s native resolution, or a lower, standard resolution as a temporary measure.
  • Similarly, check the Refresh rate setting lower down on the same page. Ensure it is set to a rate the monitor supports, typically 60Hz unless you are certain your monitor and cable support higher rates at the chosen resolution.
  • After changing the settings, the system will ask you to confirm the changes. If the display appears correctly, click “Keep changes”. If it reverts or remains problematic, the change will automatically revert after a few seconds.
  • Once the correct resolution and refresh rate are applied to the problematic monitor, it should display the image correctly, resolving the ‘Input Signal Out of Range’ error.

• Single Monitor Setup (Monitor Unusable): If the error occurs on your only monitor, or if all connected monitors show the error, accessing the display settings is impossible under normal Windows operation. In this case, booting into Windows Safe Mode is the recommended solution because it bypasses the standard graphics driver and high-resolution settings that are causing the problem.

  To boot into Safe Mode from within Windows (if you can access login screen or interact briefly):
  * Open Windows Settings by pressing Win + I.
  * Navigate to System > Recovery.
  * Under the “Advanced startup” section, click the Restart now button. Your computer will restart into the Windows Recovery Environment (WinRE).
  * Once in WinRE, select Troubleshoot.
  * Then, click on Advanced options.
  * Choose Startup Settings. You might be informed that you can change Windows startup behavior. Click Restart.
  * Your computer will restart again, presenting a list of startup options. You will typically want to select option 4 (Enable Safe Mode) or option 5 (Enable Safe Mode with Networking) by pressing the corresponding number key (4 or 5) on your keyboard.

  This will boot Windows into Safe Mode with a basic display driver, allowing you to see the screen at a low resolution. The screen might look different, with a plain background and “Safe Mode” displayed in the corners, but it will be functional.

  If you cannot even reach the Windows login screen or interact with the computer at all to initiate the “Advanced startup” process, you will need to use Windows installation or recovery media (like a bootable USB drive you might have created or can create on another computer) to access the Windows Recovery Environment.
  * Insert the bootable USB drive and start your computer. You may need to enter your BIOS/UEFI settings (often by pressing F2, Del, F10, or F12 during boot) to change the boot order to boot from the USB drive.
  * Once the Windows setup environment loads from the USB, instead of clicking “Install now”, click the Repair your computer link, usually found in the lower-left corner.
  * This will take you into the Windows Recovery Environment, similar to the process initiated from within Windows.
  * From here, follow the same steps as above: Troubleshoot > Advanced options > Startup Settings > Restart, and then select the option to enable Safe Mode (option 4 or 5).

  Once your computer has successfully booted into Safe Mode, you can then change the display resolution using the same steps outlined for the dual monitor setup: Settings > System > Display, select the monitor (even if it’s the only one listed), and choose a compatible resolution and refresh rate from the drop-down menus. After applying the changes, restart your computer normally (exit Safe Mode). The computer should now boot with the newly set resolution, resolving the ‘Input Signal Out of Range’ error.

Using Safe Mode is a powerful technique because it circumvents the specific driver or setting that might be causing the high-resolution output issue. By loading only essential components, it provides a stable environment to diagnose and correct display configuration problems before loading the full system, including the potentially problematic graphics driver.

2] Reinstall Graphics driver¶

A corrupted, outdated, or incompatible graphics driver is another frequent culprit behind display issues, including the ‘Input Signal Out of Range’ error. The graphics driver is software that allows your operating system and applications to communicate effectively with your graphics processing unit (GPU), enabling it to render images on your monitor. If this driver is faulty, it might incorrectly report supported resolutions or refresh rates, or fail to manage the signal output properly, leading to the monitor receiving an unsupported signal.

Whether you have an NVIDIA GeForce, AMD Radeon, or Intel integrated graphics chip, issues with their respective drivers can manifest as display errors. Therefore, a recommended troubleshooting step is to perform a clean reinstallation of your graphics driver. This process involves completely removing the current driver software and then installing a fresh version, ideally the latest compatible one from the manufacturer.

Here’s how you can reinstall your graphics driver:

• Access Device Manager: The standard way to manage hardware drivers in Windows is through Device Manager. You can open it by right-clicking the Start button and selecting “Device Manager” from the context menu, or by searching for “Device Manager” in the Windows search bar and opening the control panel item.
• Locate Display Adapters: In Device Manager, expand the category labeled “Display adapters”. You will see a list of your graphics cards here. If you have both integrated and dedicated graphics, both might be listed.
• Uninstall the Driver: Right-click on your primary graphics card (usually the dedicated one if you have one, or the integrated one if not) and select “Uninstall device” from the context menu.
• Confirm Uninstallation: A dialog box will appear. Crucially, check the box that says “Attempt to remove the driver software for this device” if this option is available. This ensures that the existing driver files are completely removed, preventing potential conflicts with the new installation. Then, click “Uninstall”.
• Restart Your Computer: After the driver is uninstalled, it is highly recommended to restart your computer. Windows will likely boot using a basic Microsoft display adapter driver, which will function at a low resolution (similar to Safe Mode, but in normal mode). This confirms the old driver is gone.
• Install the New Driver: Now you need to install a fresh copy of the driver.
  • Method A (Windows Update/Basic Driver): After restarting, Windows might automatically detect the hardware and install a generic driver or even download a slightly newer one via Windows Update. While this might provide a working display, it’s often not the optimal driver for performance or features.
  • Method B (Manufacturer’s Latest Driver - Recommended): For the best results, download the latest driver specifically designed for your graphics card model and your version of Windows directly from the manufacturer’s official website (NVIDIA, AMD, or Intel). Navigate to their driver download section, enter your GPU model and OS details, and download the appropriate installer.
• Run the Installer: Locate the downloaded driver installation file and run it. Follow the on-screen prompts. The installer will guide you through the process. Many installers offer an option for a “Clean Installation” or “Express vs. Custom”. Choosing “Custom” and selecting the “Perform a clean installation” option is often beneficial as it resets all driver settings to default, which can help resolve lingering configuration issues.
• Complete Installation and Restart: Once the installation is finished, the installer will usually prompt you to restart your computer to finalize the changes. Do so.

After your computer restarts with the newly installed graphics driver, the system should correctly detect your monitor and its capabilities. The display output should automatically adjust to a supported resolution and refresh rate, hopefully eliminating the ‘Input Signal Out of Range’ error. Ensure that the installed driver is indeed the latest version appropriate for your hardware to benefit from the most current compatibility fixes and performance improvements.

Additional Troubleshooting Steps¶

If the above steps involving resolution changes and driver reinstallation don’t fully resolve the issue, or if you want to cover all bases, consider these additional troubleshooting methods:

• Check Physical Connections: A simple yet overlooked cause is a loose or damaged cable connection.
  • Ensure the video cable (HDMI, DisplayPort, DVI, VGA) is securely plugged into both the back of your computer (graphics card port) and the back of your monitor.
  • Try unplugging and replugging the cable firmly at both ends.
  • If you have a spare cable of the same type, try using a different cable to rule out a faulty cable. Cables can become damaged over time.
• Verify Monitor Input Source: Monitors often have multiple input ports (e.g., several HDMI ports, a DisplayPort, a VGA port). You need to make sure the monitor is actively listening for a signal on the port you are using to connect it to your computer.
  • Use the buttons on your monitor (or its remote control, if applicable) to access its On-Screen Display (OSD) menu.
  • Find the “Input”, “Source”, or “Input Select” option.
  • Manually select the specific input port (e.g., HDMI 1, DisplayPort) that your computer is connected to. Do not leave it on “Auto” selection, as this can sometimes fail.
• Try a Different Monitor or Computer: This helps isolate the problem.
  • Connect the problematic monitor to a different computer or laptop. If it works correctly on another machine, the issue likely lies with your original computer’s graphics card or drivers/settings.
  • Connect your computer to a different monitor or even a TV. If the computer displays correctly on another screen, the issue is likely specific to your original monitor.
• Check Monitor Refresh Rate: While less common than resolution issues for this specific error message, an unsupported refresh rate can also cause the signal to be “out of range.”
  • If you can access display settings (perhaps via Safe Mode or a working secondary monitor), check the “Refresh rate” setting.
  • Ensure it is set to a value supported by your monitor at the current resolution. Standard refresh rates are 60Hz, 75Hz, 120Hz, 144Hz, etc. Consult your monitor’s manual for its supported refresh rates at different resolutions. Lowering the refresh rate to 60Hz is often a safe bet for troubleshooting.
  • You can usually find the refresh rate setting in Windows Display Settings under “Advanced display settings” or within your graphics card’s control panel (NVIDIA Control Panel, AMD Adrenalin, Intel Graphics Command Center).
• Reset Monitor Settings: Some monitors have a factory reset option in their OSD menu. Resetting the monitor to its default settings can sometimes resolve obscure compatibility or configuration issues within the monitor itself that might contribute to the error.
• Update Windows: Ensure your Windows operating system is up to date. Sometimes, OS updates include compatibility fixes for hardware and drivers that can resolve display issues. Access Windows Update via Settings (Win + I > Update & Security > Windows Update).

By systematically working through these steps, starting with resolution adjustments (especially in Safe Mode if needed) and driver reinstallation, and then checking physical connections, input sources, and refresh rates, you significantly increase your chances of resolving the ‘Input Signal Out of Range’ error and getting your monitor back to displaying correctly.

Related Concepts Explained¶

Understanding a few key terms can help in troubleshooting monitor issues:

• Resolution: The number of distinct pixels displayed on a screen, arranged in rows and columns. Expressed as width x height (e.g., 1920x1080). A higher resolution means more detail can be displayed, but requires more processing power and monitor support. Monitors have a native resolution, which is the number of physical pixels on the screen and the resolution at which the image is sharpest.
• Refresh Rate: The number of times the display updates the image on the screen per second, measured in Hertz (Hz). A higher refresh rate results in smoother motion, particularly noticeable in fast-paced videos or games. Both the graphics card and the monitor must support a specific refresh rate at a given resolution for it to work correctly. The “Input Signal Out of Range” error often means the refresh rate sent by the PC is too high for the monitor.
• Safe Mode: A diagnostic startup mode for Windows that loads a minimal set of drivers and services. It uses a basic display driver that supports only standard, low resolutions and refresh rates, making it ideal for troubleshooting display problems caused by driver or settings conflicts in normal mode.

Frequently Asked Questions¶

This section addresses common questions related to monitor signal issues.

Why is my monitor saying Input Signal not found?¶

The message “Input Signal not found” or “No Signal” is different from “Input Signal Out of Range”. While ‘Out of Range’ means the signal is present but in an unsupported format (wrong resolution/refresh rate), ‘Not found’ means the monitor isn’t detecting any signal coming in on the selected input port.

Common reasons for “Input Signal not found”:
* Loose or Disconnected Cable: The video cable is not securely plugged into either the computer or the monitor.
* Faulty Cable: The cable itself is damaged or defective and cannot transmit the signal.
* Incorrect Input Source Selected: The monitor is set to the wrong input (e.g., looking for HDMI 1 signal but the computer is connected via DisplayPort, or connected to HDMI 2).
* Computer Not Outputting Signal: The computer is off, asleep, hibernating, or experiencing a critical hardware failure (like a dead graphics card) that prevents it from sending a signal.
* Faulty Monitor Port: The specific port on the monitor is damaged.
* Faulty Graphics Card Port: The port on the computer’s graphics card is damaged.
* Power Issues: The monitor is not turned on, or the graphics card is not receiving sufficient power.

To fix “Input Signal not found”, ensure the computer is on and awake, check cable connections, try a different cable, verify the monitor’s input source setting matches the connection, and test with different ports if available.

How do I fix my monitor Input Signal Out of range?¶

To fix an “Input Signal Out of Range” problem, the primary solution is to adjust the computer’s display settings (resolution and refresh rate) to a configuration that your monitor explicitly supports.

The typical steps involve:
1. Accessing Display Settings: This is the main challenge if the monitor is unusable. You’ll likely need to:
* Use a second, working monitor if available.
* Boot the computer into Windows Safe Mode (which uses a basic, compatible display setting).
* Use Windows installation or recovery media to access the Windows Recovery Environment and boot into Safe Mode from there.
2. Changing Resolution and Refresh Rate: Once you can see the screen (in Safe Mode or via another monitor), go to Windows Display Settings.
* Select the problematic monitor.
* Choose a supported resolution (preferably the monitor’s native resolution) from the “Display resolution” drop-down.
* Choose a supported refresh rate (usually 60Hz is safe) from the “Refresh rate” drop-down (often found in “Advanced display settings”).
3. Applying and Testing: Confirm the changes. If the display works, keep the settings.
4. Restarting: If you used Safe Mode, restart the computer normally to see if the fix persists.
5. Reinstalling Graphics Driver: If changing settings doesn’t work or the issue returns, perform a clean reinstallation of your graphics driver to rule out driver corruption or incompatibility.

Other potential steps include checking physical cable connections, verifying the monitor’s selected input source, and ensuring the monitor itself hasn’t been misconfigured (e.g., via a factory reset in its OSD menu).

What is the difference between “No Signal” and “Out of Range”?¶

As mentioned earlier, “No Signal” (or “Input Signal Not Found”) means the monitor is not receiving any video data stream from the connected cable on the selected input port. It’s like a phone line where there’s no call coming through at all.

“Input Signal Out of Range” means the monitor is receiving a signal, but the characteristics of that signal (specifically the combination of resolution and refresh rate) are outside the parameters the monitor is designed to handle. It’s like receiving a phone call, but the audio is distorted or too high-pitched for you to understand. The signal exists, but it’s incompatible.

Understanding this distinction helps in diagnosing the root cause – if it’s “No Signal,” you check physical connections, cable integrity, power, and input source selection. If it’s “Out of Range,” you focus on the computer’s display output settings (resolution, refresh rate) and the graphics driver, often requiring Safe Mode to correct.

We hope this comprehensive guide helps you resolve the ‘Input Signal Out of Range’ error on your monitor. It’s a common issue when display settings exceed hardware limitations, but it’s usually fixable with the right steps.
