My Dell Laptop Screen Doesn't Display Full Screen When I Change the Resolution

If you Dell laptop computer screen isn't displaying a full-screen image after you adjust its overall resolution, this means that you've changed to a resolution that your monitor doesn't support. You've either picked a resolution that is too large or too small for your laptop's built-in screen to handle. You can correct this by switching it back to its recommended resolution, using native Windows tools.

Step

Step

Select "Screen Resolution."

Step

Choose the "Resolution" drop-down menu.

Step

Slide the vertical bar to the resolution with the word "Recommended" listed next to it.

Step
