Kerbal Space Program 2: How to Fix Widescreen and Ultra Widescreen Issue

Hey Kerbals,
If you want to play on your fancy monitor all you need to do is manually change the resolution in the settings file.

First of all close the game.

KSP 2 like many other games have a file to save your settings. For KSP 2 it is the “Settings.json” file and it can be found in:

Windows:
C:\Users\%USERNAME%\AppData\LocalLow\Intercept Games\Kerbal Space Program 2\Global

On Linux (Thanks to Cornelius V. Osmond)
<whereversteamdata>/steamapps/compatdata/954850/pfx/drive_c/users/steamuser/AppData/LocalLow/Intercept Games/Kerbal Space Program 2/Global/

You can press [WINDOWS] + [R] to open “run” and paste the path above.

Now open the “Settings.json” (right klick and select “open with …”) with the Windows editor or Notepad++
and change the line “ScreenResolution” to your resolution of your monitor.

Only edit the value of that line so whatever is between the “” eg: “1920×1080” to “5120×1440” or whatever your monitor supports.

Now save the file and run the game. Enjoy! 🙂
