# Editor.PanelWindow.ExclusiveFullscreen

```csharp
bool ExclusiveFullscreen { get; set; }
```

Whether [Editor.PanelWindow.Fullscreen](/api/Editor.PanelWindow/Fullscreen) takes the display over with a real display mode, the way
a game does, instead of a borderless window over the desktop. Off by default: borderless
switches instantly and plays well with other windows and displays.

Declared in [Editor.PanelWindow](/api/Editor.PanelWindow).
Assembly: `Sandbox.Tools`.
