For some reason Rockstar decided to add a "display device selection" window that annoyingly shows up every time you start GTA: San Andreas if you have multiple monitors attached to your computer.

This mod skips that window.
It really just waits for it to show up and press enter, you probably won't even see it anymore.

To install simply place "SkipDeviceSelection.asi" from inside the .zip file you've downloaded inside your GTA San Andreas folder. If you use Steam, this is usually at "(...)\steamapps\common\Grand Theft Auto San Andreas".

You probably don't need to reconfigure which screen you want to use every time you start the game as it saves the last selection, but if you do simply rename "SkipDeviceSelection.asi" to "SkipDeviceSelection.asi.bak", start the game and configure it, then quit the game and rename it back to it's original .asi extension.
