Unity games for Surface Duo

Dual-screen and foldable SDKs can be incorporated into Unity mobile games to allow the game view to adapt to a variety of devices including the Microsoft Surface Duo.

Choose an SDK

There are two different SDKs available:

  • Jetpack Window Manager - supports dual-screen and foldable devices from a variety of manufacturers, including Surface Duo. Recommended for dual-screen and foldable device support across a variety of devices from different manufacturers.
  • Microsoft dual-screen SDK - supports the Microsoft Surface Duo.

Game preview in Unity

To help with your game development, use the game resolution picker to create custom configurations for Surface Duo screens:

  • 2784×1800 – Surface Duo double portrait
  • 1800×2784 – Surface Duo double landscape
  • 1350×1800 – Surface Duo single portrait
  • 1800×1350 – Surface Duo single landscape

You can then add the following code snippet in your game to simulate the hinge area:

// Hardcode the hinge mask for the Unity game preview
if (Screen.width == DeviceHelper.SURFACEDUO_SPANNEDWIDTH)
{ // double-portrait
    GUI.backgroundColor = Color.gray;
    GUI.Box(new Rect(x: DeviceHelper.SURFACEDUO_SCREENWIDTH, y: 0, width: DeviceHelper.SURFACEDUO_HINGEWIDTH, height: DeviceHelper.SURFACEDUO_SCREENHEIGHT),"");
else if (Screen.height == DeviceHelper.SURFACEDUO_SPANNEDHEIGHT)
{ // double-landscape
    GUI.backgroundColor = Color.gray;
    var r = new Rect(x: 0, y: DeviceHelper.SURFACEDUO_SCREENWIDTH, width: DeviceHelper.SURFACEDUO_SCREENHEIGHT, height: DeviceHelper.SURFACEDUO_HINGEWIDTH);
    GUI.Box(r, "");


These values are just to simulate the hinge area in the preview – you should not hardcode these values in your game code, instead use the APIs provided to query for the screen and hinge dimensions.
