Dungeon Defenders II: How to Add Ultrawide / 21:9

How to add Ultrawide / 21:9 (or I guess any) resolution options in the settings menu.

Go to your Dungeon Defenders 2 folder

Method 1

  • Open Steam
  • Go to your Steam Library
  • Right click “Dungeon Defenders 2”
  • Hover over “Manage >”
  • Click “Browse local files”

The “Dungeon Defenders 2” folder should now be open

Method 2

  • Open Steam
  • Go to your Steam Library
  • Right click “Dungeon Defenders 2”
  • Click “Properties”
  • Click “Local Files” on the sidebar of the popup
  • Click “Browse…”

The “Dungeon Defenders 2” folder should now be open

Method 3
Navigate to it via File Explorer, I’m not explaining that.

Navigate to the ini file

Inside your “Dungeon Defenders 2” folder

  • Open the “DunDef2” folder
  • Open the “UDKGame” folder
  • Open the “Config” folder
  • Open “DefaultDunDef.ini” with Notepad or other Text Editor
  • Inside of the “DefaultDunDef.ini” file, scroll down to the “[UDKGame.DunDefViewportClient]” section
  • Under that section there will be 15 ish “SupportedResolutions[_]=”___x___””
  • Pick one and replace the resulution in quotes with your desired reslution

For example I replaced: SupportedResolutions[15]=”3840×2160″ with SupportedResolutions[15]=”3840×1600″ because thats my mononiter’s reslution.

In-game

If you did it correctly when you launch the game and open the options menu the drop-down selector should now list whatever resolution you added
