Black Screen After Launching League of Legends

League of Legends (LoL) has remained among the most popular online video games ever since its launch way back in 2009. The longevity and continued success of the game are due to the engaging gameplay of the MOBA (Multiplayer Online Battle Arena) genre, the regular release of new exciting champions, and the expanded universe created by the Riot Games studio that includes several spin-off games, music acts and more. 

Unfortunately, as with any software product, League of Legends also has its fair share of issues. One of the more common problems experienced by users is seeing a black screen after launching the game. This black screen may appear after pressing Alt+Tab during the logging process or immediately after picking a champion. It also could be caused by running the game in full-screen mode, having the game resolution be bigger than the desktop resolution or by a myriad of other factors. 

However, there are a couple of options that might be able to deal with this issue. Explore the potential fixes outlined below and see if one of them manages to help you.

Run LoL as an administrator

  1. Locate the LoL game launcher and right-click it.
  2. Select 'Properties.'
  3. Go to the 'Compatibility' tab.
  4. Find the 'Run this program as an administrator' option and check the corresponding box.
  5. Click 'Apply' followed by 'OK' to save the changes.

Disable Display Scaling

  1. Locate the LoL game launcher and right-click it. 
  2. Open 'Properties.'
  3. Select the 'Compatibility' tab.
  4. Click the 'Change high DPI settings' button located in the 'Settings' section of the window.
  5. Now, find the 'Override high DPI scaling behavior' option and check its corresponding box.
  6. Click 'OK.'
  7. Back in the 'Compatibility' tab, uncheck the 'Run this program in compatibility mode' option. Then check the 'Run this program as an administrator' box.
  8. Click 'Apply' followed by 'OK.'

Update the Graphics Driver

The black screen also could be caused by malfunctioning or outdated graphics card (GPU) drivers. To see if this is the case, check if a new driver package has been released for your specific GPU model. Users can do this manually from the official websites of either NVIDIA or AMD. An alternative is to let Windows try and install any more recent drivers via Device Manager automatically.

  1. Right-click the Start menu button and choose 'Device Manager' from the available options.
  2. In the new window, locate the 'Display adapters' section and expand it by clicking on the node icon in front.
  3. Find your GPU, right-click it, and select 'Update driver.'
  4. Windows will open a prompt asking the user to choose the preferred method for finding a new driver. Users can let Windows do it automatically or point the system to a previously downloaded driver file on the system. Pick the one that better suits your needs.
  5. Wait for Windows to install the driver and see if the black screen issue in LoL has been fixed.
