If you hear audio but see a black screen in League of Legends, try these steps: 1. Run the game in windowed mode. 2. Disable fullscreen optimizations. 3. Update or reinstall graphics drivers. 4. Launch as administrator. 5. Adjust GPU settings for performance. 6. Verify game files via the Riot Client.

If you're experiencing a black screen in League of Legends but can still hear the game audio, the issue might be related to display or graphics settings. Here are several methods to resolve it:

The operating environment of this tutorial: Dell XPS 15, Windows 11

1. Run the Game in Windowed Mode

Forcing the game to run in windowed mode bypasses potential fullscreen rendering issues that may cause a black screen while audio continues to play.

• Locate the League of Legends shortcut or executable file (lol.launcher.exe or lol.launcher.admin.exe).
• Right-click the shortcut and select "Properties".
• In the "Target" field, append -windowed at the end of the path, right before the closing quotation mark.
• Click "Apply" and then launch the game.

2. Disable Fullscreen Optimizations

Windows fullscreen optimizations can interfere with older or graphics-intensive games like League of Legends, leading to display issues even when sound works.

• Navigate to the installation folder of League of Legends (typically under "Riot Games" in Program Files).
• Right-click on lol.launcher.exe and select "Properties".
• Go to the "Compatibility" tab.
• Check the box for "Disable fullscreen optimizations".
• Click "Apply" to save the changes.

3. Update or Reinstall Graphics Drivers

Outdated or corrupted GPU drivers are a common cause of black screens in games. Ensuring your graphics drivers are up to date can restore proper rendering.

• Press Win X and select "Device Manager".
• Expand the "Display adapters" section.
• Right-click your GPU and choose "Update driver".
• Select "Search automatically for updated driver software".
• If no update is found, visit the official website of NVIDIA, AMD, or Intel to download the latest driver manually.
• Alternatively, choose "Uninstall device" and restart your PC to reinstall the driver.

4. Launch the Game as Administrator

Running the game with elevated privileges can resolve permission-related issues that may prevent the game window from rendering properly.

• Right-click the League of Legends launcher shortcut.
• Select "Run as administrator".
• If prompted by User Account Control, click "Yes".
• Allow the game to launch and check if the black screen persists.

5. Modify NVIDIA/AMD Graphics Settings (if applicable)

Custom GPU settings may conflict with the game’s display mode. Resetting or adjusting them can restore visual output.

• Open the NVIDIA Control Panel or AMD Radeon Software.
• Navigate to "Manage 3D Settings".
• Find the League of Legends executable under "Program Settings".
• Set "Vertical sync" to "Off" and "Power management mode" to "Prefer maximum performance".
• Set "Preferred refresh rate" to "Highest" and "Fullscreen mode" to "Exclusive fullscreen".
• Apply the settings and restart the game.

6. Verify Game Files via Riot Client

Corrupted or missing game files can lead to rendering failures. Verifying the integrity of the game files ensures all components are functional.

• Open the Riot Client and go to your game library.
• Hover over League of Legends and click the gear icon.
• Select "Verify" from the dropdown menu.
• Wait for the process to complete, which may take several minutes.
• Once done, restart the client and launch the game.
