The most common cause is old or broken graphics drivers. Other reasons can include problems with Riot Vanguard, full-screen mode issues, or overlays from other apps like Discord or Overwolf. Here are some practical solutions you can try to fix the black screen problem:
1. Switch to a Single Monitor Setup
For some people, the black screen in League of Legends happens because they are using more than one monitor. Dual-monitor setups sometimes cause games to display incorrectly. To see if this is the cause, try disconnecting your second monitor or switching to a single monitor mode.
2. Run League of Legends with High DPI Override
Enabling high DPI override allows the game to scale better on high-resolution displays. Turning on this option for League of Legends can not only make graphics look sharper but may also fix the black screen issue. Make sure you do this on the main League of Legends program file, not a shortcut. If you have a shortcut, right-click it and choose ‘Open file location’ first.
3. Perform a Clean Boot
A clean boot starts Windows with only the essential services and drivers, allowing you to identify if other background programs are interfering with the game. If you’re seeing a black screen, it’s quite likely a third-party service or app is interfering. Doing a clean boot is a good way to rule this out.
4. Update Your Graphics Driver
A black screen is often related to issues with your graphics card drivers. Updating your GPU drivers directly from the manufacturer is the best way to rule out any driver problems. Instead of updating drivers through Device Manager, use the GPU manufacturer’s software like Nvidia GeForce Experience or AMD Radeon Software, or download the latest drivers from the official website.
5. Reinstall the Game
If you’re still seeing a black screen after trying the steps above, reinstalling League of Legends can help fix any corrupted game files. If you have tried all of the steps above and the problem still isn’t fixed, you can contact the League of Legends support team for more help. Their support team is ready to answer your questions and assist with any technical issues you’re experiencing.
