Before trying these fixes, you should:

  • Ensure that all your cables are properly fitted, especially if you use a desktop.
  • Reset your monitor, so open its on-screen display (OSD) menu. Then look for a Factory Reset option on that menu. If you can’t find such an option, check your monitor’s manual for further details about how you can reset your VDU.

1. Update your graphics card’s driver

  1. Press Windows Key + X to open the Power User Menu. Select Device Manager from the list.
  2. Expand Display adapters, double-click your graphics card, go to the Driver tab and click the Update Driver.
  3. Click Search automatically for drivers.

Alternatively, try scanning your PC with driver updater software to tell you if your GPU has an outdated driver. Assuming it does, you can install the latest GPU driver with the driver updater utility.

Most common Windows errors and bugs can result from faulty or incompatible drivers. An outdated system can lead to lags, system issues, or even BSoDs.

You can prevent these problems by using an automatic tool that will search and install the correct drivers on your computer with just a few clicks. That's why we recommend you use Outbyte Driver Updater. Here's how to do it:
  1. Download and install the Outbyte Driver Updater app.
  2. Launch the software.
  3. Wait for the app to detect all incompatible drivers.

3. Adjust your PC’s Power settings

1. Open the Windows search tool, which you can do by pressing the Windows and S keys simultaneously.

2. Type the keyword Control Panel within the search tool’s text box, then click Control Panel to open that window.

3. Click the View by menu and select the Category option on it.

4. Select Hardware and Sound.

5. Choose Power Options.

6. Select either the High Performance or Balanced setting. It doesn’t matter which, but the Power Saver option must not be selected.

7. Then click to Change plan settings for your preferred plan.

8. Select Never on the Turn off the display drop-down menu, and click the Never option for the Put computer to sleep drop-down menu.

choose never

9. Press the Save changes button.

If you experience issues with your computer screen going black by itself from time to time, you should tweak your Power Settings.

It is likely that the Power Saver option is causing you this problem. Therefore, choosing another Power Plan and configuring it to never turn off the display should get your PC working properly again.

4. Undo any user-applied PC overclocking

Users who overclock their PCs with third-party software might be able to resolve the issue by disabling their overclocking.

If you’ve applied any CPU or GPU overclocking, restore your PC to its default settings with your overclocking software. Then uninstall your overclocking software for good measure.

Those are some of the most likely fixes for a monitor that keeps going black. However, if the fixes do nothing for you, it might be an issue with the monitor itself.

You can return your monitor to its manufacturer for free repairs, or a replacement, so long as it’s still within its warranty period.
