Why is my screen dark, but my brightness is all the way up?

There are various factors why your screen could be so dark even at full brightness on your Windows 10 laptop. Let’s look at some of the causes in detail:

This feature can be why your screen is so black suddenly. You need to disable adaptive brightness if you want to keep your screen bright at all times.
  • Outdated display driver: Your display driver can start misbehaving when it is outdated. It could be the reason for this issue and cause other problems. The quickest solution here is to update your drivers.
  • Issues with PC power settings: In some cases, issues with your PC power settings might be the ones messing with your screen brightness. Running the Power troubleshooter should diagnose and recommend possible fixes for this.

How do I fix a screen that is too dark at full brightness?

Here’s what you should do first:

  • While this may not always work, you should try holding down the Fn (small n) key on your keyboard while holding the Up arrow key. This should increase the screen brightness. The reverse is the case, so pressing Fn + Down arrow will reduce brightness.

1. Disable adaptive brightness

  1. Press the Windows key + I to open the Settings app and select the System option.
