Common Causes

How to fix a monitor displaying 'Input Not Supported' or 'Out of Range' error

An "Input Not Supported" or "Out of Range" error occurs when your computer sends a video signal to your monitor that the screen cannot display. This usually happens if the resolution or refresh rate is set higher than the monitor's capabilities. This guide will help you restore your display by adjusting these settings.

Quick Fix Steps

  1. Turn off your monitor and computer.
  2. Restart your computer and boot into Safe Mode to load a basic display driver.
  3. Adjust your display settings to a supported resolution.
  4. Restart your computer normally.

Detailed Instructions

For Windows 10 and Windows 11

  1. Right-click on an empty area of your desktop and select Display settings.
  2. Scroll down and click Advanced display (Windows 11) or Advanced display settings (Windows 10).
  3. Under Display resolution, select the resolution marked as (Recommended).
  4. Click Display adapter properties or Display adapter properties for Display 1.
  5. Go to the Monitor tab.
  6. Under Screen refresh rate, select a lower value (e.g., 60 Hertz).
  7. Click Apply and then OK.

For macOS

  1. Click the Apple menu () and select System Settings (or System Preferences on older versions).
  2. Click Displays in the sidebar.
  3. Select a resolution from the list that matches your monitor's native specifications.
  4. If available, adjust the Refresh Rate dropdown to a supported value.
Tip: If you cannot see the screen to navigate menus, try restarting your computer. Windows will often automatically reset the resolution to a safe default if it detects no signal for several seconds.

Troubleshooting

Using Safe Mode

If you cannot access your settings because the screen remains blank or shows the error, boot into Safe Mode:

  1. Hold the Shift key while clicking Restart from the Windows login screen.
  2. Select Troubleshoot > Advanced options > Startup Settings > Restart.
  3. Press 4 or F4 to enable Safe Mode.
  4. Once logged in, follow the Windows steps above to lower your resolution.

Check Your Cables

Caution: Avoid selecting resolutions or refresh rates that exceed your monitor's specifications, as this can cause the "Out of Range" error to return. Check your monitor's manual for the maximum supported settings.
