How to Fix Monitor Not Displaying Full Screen in Windows 11

A monitor not displaying in full screen on Windows 11 can be frustrating, especially when parts of the desktop are cut off, black borders appear around the screen, or applications don’t fit properly. This issue commonly occurs after changing display settings, updating graphics drivers, connecting a new monitor, or switching resolutions.

The problem is usually related to incorrect screen resolution, scaling settings, graphics driver configuration, or monitor aspect ratio mismatches. In some cases, HDMI scaling or GPU control panel settings can also prevent the display from filling the entire screen.

In this guide, we’ll walk you through effective methods to fix a monitor not displaying full screen in Windows 11.
