Make Rocket League Dual-Monitor

README.md

Use these scripts to make Rocket League work on your Dual Monitor setup.

Download them somewhere onto your computer.

If you have two 1920x1080, or two 1920x1200 screens, you do not need to modify the scripts at all.

If you have a different resolution, then change the numbers below. For example, if you have a pair of 2560x1440 screens, then you will have to change 1920 to 2560 in both files, and you will have to change 3840 to 5120 in both files

If your screens have different heights, then Rocket League does not work well with that.

If your screens have different widths, then add the widths together, and change both instances of 3840 with your width sum.
