Before anything, perform the following:

  • Ensure that your monitor is connected tightly and that it receives power from the wall outlet or the power adapter.
  • If your monitor uses a detachable video cable, ensure you get a second monitor cable that you can use for testing purposes whenever your primary cable fails.
  • Confirm if your monitor’s power lights come up whenever you try to power it on.
  • Ensure to use a dedicated graphics driver. Many Nvidia owners that use DisplayPort connection reported that updating DisplayPort firmware fixed the issue for them.
  • Try to connect your monitor to another computer. This will help you determine if the monitor is working.
  • Connect the monitor to the motherboard graphics. This will help you determine if your dedicated GPU is the cause of the problem.

Having confirmed the above checks, if the problem persists, you can work through any of the advanced solutions below.

1. Perform an inspectional restart on your laptop
