How to Fix Monitor Not Turning On Error in Windows 11: Step-by-Step Solutions

It can be frustrating when your monitor doesn’t turn on after powering up your Windows 11 PC. This issue could be caused by simple connection problems or deeper hardware or software faults. Fortunately, many common causes have straightforward fixes.

In this guide, you will find easy, step-by-step solutions to get your monitor working again with minimal hassle. Even if you are not very tech-savvy, these instructions will help you troubleshoot effectively.

Follow the steps carefully and check your monitor after each one to see if the problem is resolved. This way, you won’t waste time trying unnecessary fixes.

Let’s start with some quick checks before moving on to detailed troubleshooting.

Quick Note: Prerequisites and Basic Checks

  • Ensure the monitor is plugged in: Check that the power cable is securely connected to both the monitor and the power outlet. Sometimes a loose plug can cause the monitor not to power on.
  • Power button: Confirm that you have pressed the monitor’s power button. Some monitors have separate buttons for power and input selection.
  • Check power outlet: Test the power outlet with another device to make sure it’s supplying power.
  • Verify cables: Make sure the video cable (HDMI, DisplayPort, VGA, or DVI) is properly connected to both the monitor and your computer.

Step 1: Restart Your Computer and Monitor

Sometimes, a simple restart can resolve display issues caused by temporary glitches.

  1. Turn off your computer completely by clicking on Start > Power > Restart.
  2. Turn off the monitor using its power button and unplug it from the power source.
  3. Wait for about 30 seconds to 1 minute.
  4. Plug the monitor back in and turn it on.
  5. Once the monitor is on, let your computer boot fully.

This step helps clear any temporary system errors and re-establishes the connection between your PC and monitor.

Step 2: Check and Reconnect All Cables

Loose or damaged cables are a very common reason why monitors don’t display anything.

  1. Turn off both the computer and the monitor.
  2. Unplug the video cable from both the monitor and the PC.
  3. Inspect the cable for visible damage such as cuts or bent pins.
  4. If you have a spare video cable, try using it to rule out cable issues.
  5. Reconnect the cable firmly to the monitor and PC.
  6. Power on the monitor and then the PC.

If the monitor still doesn’t turn on, try connecting it to a different video port on your computer, such as switching from HDMI to DisplayPort, if available. This will help check if a specific port is malfunctioning.

Step 3: Test the Monitor on Another Device

This step helps identify whether the problem lies with the monitor or your PC.

  1. Disconnect the monitor from your current PC.
  2. Connect the monitor to a different computer or a laptop using the same cable and port type.
  3. Turn on the monitor and the other device.

If the monitor works on the second device, the issue likely comes from your PC or its settings. If it still doesn’t turn on, the monitor may need repair or replacement.

Step 4: Adjust Display Settings in Windows 11

Sometimes Windows fails to detect the monitor correctly or sends the display output to another screen. Adjusting display settings may fix this.

  1. Press Windows + P keys together to open the Project menu.
  2. Use the arrow keys or mouse to select Duplicate or Extend, then press Enter.
  3. If you have multiple monitors, this will ensure the display is sent to the correct screen.

Alternatively, open Settings > System > Display and click Detect under Multiple displays to force Windows to look for connected monitors.

Step 5: Update or Reinstall Graphics Drivers

Outdated or corrupted graphics drivers can prevent the monitor from displaying properly. Updating or reinstalling drivers can solve this.

  1. Right-click the Start button and select Device Manager.
  2. Expand the Display adapters section.
  3. Right-click your graphics card and select Update driver.
  4. Choose Search automatically for updated driver software.
  5. Follow the prompts to install any updates.
  6. If updating doesn’t help, right-click the graphics card again and select Uninstall device. Then restart your PC to force Windows to reinstall the driver automatically.

Keeping drivers up to date ensures compatibility and resolves many hardware detection problems.

Step 6: Check Power Management Settings

Windows power settings sometimes put your display or graphics adapter into a low power state.

  1. Open Settings > System > Power & battery.
  2. Click Screen and sleep.
  3. Make sure the display is set not to turn off immediately or too quickly.
  4. Also, open Device Manager, right-click your graphics adapter, select Properties, and go to the Power Management tab if available.
  5. Uncheck options that allow the computer to turn off the device to save power.

This prevents your graphics card from being disabled unexpectedly.

Step 7: Reset Monitor to Factory Settings

If your monitor has an on-screen menu button, try resetting it to factory defaults.

  1. Use the monitor’s buttons to navigate to the Settings or Menu.
  2. Find an option like Factory Reset or Reset All Settings.
  3. Confirm to reset the monitor.
  4. Turn off and on the monitor to check if the issue is fixed.

This clears any incorrect settings that might prevent the monitor from displaying.

Frequently Asked Questions (FAQs)

Why does my monitor say “No signal” even though it’s turned on?

This usually means the monitor is powered but not receiving a video signal from the PC. Check that the video cable is properly connected, the correct input source is selected on the monitor, and your PC is on and not in sleep mode.

Can a faulty graphics card cause the monitor not to turn on?

Yes. If the graphics card is damaged or poorly seated in its slot, it may fail to send a video signal. Testing with another monitor or integrated graphics (if available) can help confirm this.

How do I select the correct input source on my monitor?

Most monitors have an Input or Source button on the front or side panel. Press it to cycle through HDMI, DisplayPort, VGA, etc., until you see the display from your PC.

Is it necessary to update Windows to fix monitor issues?

Windows updates often include important driver and system fixes. Keeping Windows updated can improve hardware compatibility and resolve bugs.

What if my monitor turns on but the screen is black?

This can be caused by incorrect brightness settings, faulty cables, or display settings. Try increasing brightness, checking cables, and using the Windows + P shortcut to cycle display modes.

When Nothing Works

If you have tried all the above steps and your monitor still does not turn on, it may be a hardware failure. Here are some final options:

  • Test your monitor and cables on another known-working PC to isolate the problem.
  • Contact the monitor manufacturer’s support for warranty service or repairs.
  • Visit the official Microsoft support page for Windows 11 display issues: https://support.microsoft.com/en-us/windows.
  • Consider taking your PC and monitor to a professional technician for diagnosis.

Conclusion

Monitor not turning on can be caused by simple connection issues, incorrect settings, or hardware problems. Starting with basic checks like power and cable connections often resolves the issue quickly.

Progressively moving through display settings, driver updates, and hardware tests helps identify the root cause efficiently. Remember to test your monitor on other devices to narrow down where the problem lies.

By following these step-by-step solutions, you can fix most Windows 11 monitor issues without expert help. If problems persist, professional support may be necessary for hardware repairs.
