Why is My Dell Monitor Not Working?

Monitors like every other piece of hardware can run into problems from time to time. If you have the input source set differently than your input cable, it results in your display running into errors. Wrong input source is not the only possible cause, let’s look at the most common ones.

  • External physical damage.
  • Outdated drivers.
  • Corrupted Windows.
  • Missing important windows updates.
  • Hardware Issue.
  • Wrong Input.

How to Fix Dell Monitor Not Working?

Something as versatile as a monitor, various problems leading from small to big can cause problems. While you can sometimes get away with it with just a simple restart, it is not always the case. Let’s look at some of the known fixes that help solve the problem.

Before proceeding with any of the methods below, try connecting it with a different working monitor and check if it works.

Updating Graphics Driver

The GPU (Graphic Processing Unit) in your system is what displays the actual content on the monitor. If the drivers to such GPUs are outdated / corrupted, this causes various issues like screen flickering, going blurry, and such. 

Always ensure your GPU is up-to-date with the latest version to eliminate any possible issues caused by it.

To update the drivers of your system, follow these steps:

  1. Press Windows Key + R to open up the Run command line and type in: devmgmt.msc.
  2. Expand the Display adapters,
  3. Right-click on your GPU and select Update Driver.
    Graphics-driver-Update-
  4. Click on Search automatically for drivers, this let’s Windows search for any updated drivers and install them automatically.
    updating drivers
  5. Select Browse my computer for drivers and Let me pick to manually select a driver version.

Furthermore, if you use any third-party GPU like NVIDIA or AMD, you can head directly to their website to download and install the latest drivers for your specific graphics.

Troubleshoot Physical Damages
broken cables

Display & power cables are arguably the most crucial components of a monitor. Since they power the monitor to function and work, any damages suffered can result in the display not working properly.

  1. Unplug all the display cables, including the power cable, and replug them.
  2. Ensure that all the cables are connected properly (not wiggling or moving).
  3. Inspect the ports on the Monitor, and make sure there are no dust particles in the way.
  4. Clear off any dust, debris, or foreign particles in the ports, if you find any.
  5. Additionally, inspect the cable notches, and see if there is any damage like bent pins, and frayed notch.
Note: If your monitor only outputs a display when the cable is connected in a certain position then it is likely that the notch is damaged or the display ports contain problems. 

Test With Safe Mode

The safe mode feature allows you to figure out the root of the problem within your system. This is helpful when determining the exact reason for your monitor problems. If you successfully boot into Safe Mode without any problems, this means that the problem is within your system and not the monitor itself.

To boot into Safe Mode, follow these steps:

  1. Turn off your system completely.
  2. Hit the Power button to turn on your system.
  3. Once the system starts to boot up, press and hold the power button and turn off your device.
  4. Repeat the same process once again. This depends upon your specific system. You may have to do it more than once.
  5. Now, the next time you turn on your system, you should go into the Window Recovery Environment.
  6. On the Recovery mode window, go into Troubleshoot > Advanced options > Startup Settings and then hit Restart.
    Windows-Advanced-UEFI-Restart
  7. When your system restarts again, you will get prompted with a list of Safe Mode options. Choose the one you prefer.

While in the Safe Mode, inspect the resolution as well. Sometimes, being on a resolution that is not supported by the monitor can result in issues like black screen and distortion.

  1. Press Windows Key + I to open settings.
  2. Click on System.
  3. Under Display resolution, set the resolution to the recommended one.
    display-resolution
  4. Additionally, set the scaling option to recommended as well. 

Resetting the Monitor

If you have changed the monitor settings knowingly or unknowingly in the past, this can very well be the reason it is not working. It is a very integral part of a monitor, as you are changing how the monitor functions. Therefore, the first thing you should try is resetting it to the factory settings.

Dell-Monitor-OSD-Menu-Factory-Reset

Dell monitors are readily equipped with a feature called an on-screen display(OSD) menu. This menu allows you to reset the monitor to default settings without any hassle. You can use the physical buttons on the monitor to operate the menu (this varies depending on the model).

Since the way you operate the menu depends on the model of your monitor, refer to Dell’s Manual Support site for your specific monitor’s guide. 

  1. Navigate to the Dell Manual Support site.
  2. Insert your specific monitor’s details.
    Dell-Website-Support-Manuals-Search
  3. Now, go through the User’s guide for your monitor to see how to access the OSD Menu.
Note: Be careful when changing the settings on the OSD (On-Screen display) menu, it automatically saves changes when you go to either the next menu or close it.

Diagnosing Monitor

Sometimes, the monitor itself can be faulty or have other problems that are causing display issues. It may be difficult to differentiate whether the problem is with the monitor or your system itself. Fortunately, Dell monitors come with a feature called the Built-in Self Test tool, which helps us determine what the problem is.

  1. Navigate back to the Dell Manual Support site.
  2. Enter in your monitor’s details (Model Number).
  3. Now, scroll down to Manuals and Documents and open the User Guide.
  4. Navigate to the Troubleshooting and read the Built-in Diagnostics section to figure out the steps.

Additionally, you can run the Self-Test Feature Check to further troubleshoot the functionality of the monitor. The steps to run the test are mentioned under the same Troubleshooting guide.

Doing a System Restore

Performing a system restore allows you to revert all the settings, integrated system files, and everything back to a certain time stamp. If you are highly doubtful that changes you made to some settings may have caused the problem, go ahead and perform a system restore.

  1. Press Windows Key + R and type, control to open up the Control Panel.
  2. Next, navigate to Recovery and then select Open System Restore.
  3. You can either choose Recommended restore if you think any latest updates or drivers are causing the problem. Or, select Choose a different restore point to choose a specific time stamp for restore.
    Windows-Choose-System-Restore-Point
  4. Now, hit Next and let the operation finish.

Reset BIOS Settings

If in fact, the problem is with your system, you might want to check the BIOS settings. A BIOS is responsible for booting your system and controlling the link between your Operating system and the other components like Monitor. If you have made changes to the settings in the past, reset the BIOS back to default.

If you do not know how to reset BIOS, you can refer to this guide which explains How to Reset BIOS safely.
