Understanding the Black Screen Issue

When alt-tabbing out of League of Legends, some players may experience a black screen or a game that doesn’t return to the desktop as expected.


This issue can occur due to various reasons, such as GPU settings, fullscreen optimizations, or graphics driver conflicts.

Optimize In-Game Settings

Before diving into more complex solutions, start by optimizing the in-game settings:

#1. Windowed or Borderless Window

Switch to either windowed or borderless window mode in the game settings.

These modes generally provide smoother alt-tabbing experiences compared to fullscreen mode.

#2. Frame Rate Limit

Limit your FPS (frames per second) within the game settings. This can help alleviate potential conflicts during alt-tabbing.

Run League of Legends as Administrator

Running the game with administrative privileges can help resolve certain compatibility issues:

  1. Locate the game executable (usually “LeagueClient.exe” or “League of Legends.exe”).
  2. Right-click the executable and select “Run as administrator.”

Disable Third-Party Overlays

Certain third-party overlays, such as Discord or Nvidia GeForce Experience, may conflict with League of Legends when alt-tabbing.

Temporarily disable these overlays and test if the black screen issue persists.
