by

League of Legends is one of the  popular multiplayer online battle arena games that’s developed by Riot games and is available for the Windows and MacOS platform. In this game, players will control a champion, and battle against the opposing team with the main goal of destroying their Nexus. Although this is a solid performing game there are instances when certain issues can occur in Windows 10 which we will be addressing today. In this latest installment of our troubleshooting series we will tackle the League of Legends black screen in windows 10 issue.

Before performing any of the recommended troubleshooting steps listed below it’s best to restart your computer first. This action refreshes the operating system and removes any corrupt temporary data that could be causing the problem.

There are several factors that can cause this particular problem ranging from a scaling issue to an outdated driver. Listed below are the recommended troubleshooting steps you need to do to fix this problem.

Try to disable the display scaling

The display scaling feature works by adjusting the size of text, icons, and navigation elements to make a computer easier for people to see and use. When this feature is enabled sometimes it can interfere with the way League of Legends runs so to eliminate the possibility of this factor causing the problem you should try to disable it.

  • Right-click on the League of Legends launcher
  • Go to Properties, and then to Compatibility
  • Check Disable Display Scaling on high DPI Settings
  • Check Run as Administrator
  • Uncheck the Compatibility mode

Try checking if the black screen issue on League of Legends still occurs.
