## Items

| Name | Value | Description |
| --- | --- | --- |
| `ScaleToPhysicalSize` | 0 | Scales the simulated viewport so that its pixels correspond to their physical size on the developer's monitor, computed from the screen DPI and an optional target DPI override. |
| `ActualResolution` | 1 | Renders the simulated viewport at a 1:1 pixel mapping with no scaling applied. |
| `FitToWindow` | 2 | Scales the simulated viewport uniformly to fill as much of the available Studio window as possible while preserving the device's aspect ratio. |
