This is pretty simple but you need a Hex editor to do it. I used HXD[mh-nexus.de]

After you have installed the hex editor open [SteamDirectory]\steamapps\common\Life is Strange 2\LIS2\Binaries\Win64\LIS2-Win64-Shipping.exe

Go to Search > Replace

When that window opens choose the Hex-Values tab and add these values:

• Search for: F6 41 2C 01
  
• Replace with: F6 41 2C 00​

Choose to Replace All and wait for it to finish.

This will remove the black bars on the screen but we still need to fix the FOV.

You can accomplish that by using these values:

• Search for: 35 FA 0E 3C A4 70 7D 3F
  
• Replace with:
  
• Aspect Ratio

  Hex-Code

  64:27

  F3 EF 37 3C A4 70 7D 3F

  21:9

  34 E5 38 3C A4 70 7D 3F

  32:9

  8D 2C 64 3C A4 70 7D 3F

Choose to Replace All and wait for it to finish.

Go to File > Save and then close the program and you are done.

Note: My aspect ratio is 32:10 but using the 32:9 fix worked for me.
