Static Screen Resolution Utility for Unity 3D with Common Resolutions

Static Screen Resolution Utility

Setup

Add this script to your project and call it from one of your game's MonoBehaviours. You do not need to attach it to a Game Object, it will work from your Assets folder.

Example

void Awake()
{
#if PLATFORM_STANDALONE_WIN
  ScreenResolutionUtility.SetScreenResolution(CommonScreenResolutions.gameConsole_16bit_super_4x3, FullScreenMode.FullScreenWindow, 30);
#elif UNITY_EDITOR
  //Do nothin
#else
  ScreenResolutionUtility.SetScreenResolution(CommonScreenResolutions.gameConsole_16bit_super_4x3, FullScreenMode.Windowed, 30);
#endif
}

I wrapped this code in preprocessor blocks to avoid forcing fullscreen on all platforms.

Explanation

This script is using Screen.SetResolution( ... ); to set the screen's resolution. The real work was figuring out the common resolutions and adding them to a big switch statement.

NOTE:

You can set this once from the preferences as well. Uncheck "Default is Native Resolution" and you will be able to type in any value for the resolution. This will be set per platform. Make sure you account for all of the platforms you are publishing to.
