Added in BYOND 516.

### Applies to
- [Main](https://ref.dm-lang.org/skin/control/main.md)
- Global


### Format
> `number`

### Default value
> `1`

Read-only and unlisted parameter that returns the DPI scaling factor. A value of 1 indicates 100%. This is currently system-wide for the whole application and won't vary by window, but is implemented for windows in case future scaling changes allow them to differ.

This is also a special global parameter. Calling [winget()](https://ref.dm-lang.org/proc/winget.md) with no `id` and `dpi` as the parameter will return the system DPI scaling.

> [!note]
> 
> The DPI scale is currently set at the time Dream Seeker starts, and does not change after that.
