# UIScreen.OverscanCompensation

Describes different techniques for compensating for pixel loss at the edge of the screen.

```
enum OverscanCompensation
```

## Topics

### Constants

[`UIScreen.OverscanCompensation.scale`](/documentation/UIKit/UIScreen/OverscanCompensation-swift.enum/scale)

The final composited framebuffer for the screen is scaled so that all pixels lie in the area visible on the screen.

[`UIScreen.OverscanCompensation.insetBounds`](/documentation/UIKit/UIScreen/OverscanCompensation-swift.enum/insetBounds)

The screen bounds are reduced in size so that all pixels in the framebuffer are visible on the screen.

[`UIScreen.OverscanCompensation.none`](/documentation/UIKit/UIScreen/OverscanCompensation-swift.enum/none)

No scaling occurs. Use [`overscanCompensationInsets`](/documentation/UIKit/UIScreen/overscanCompensationInsets) to get the insets required to avoid clipping.

[`insetApplicationFrame`](/documentation/UIKit/UIScreen/OverscanCompensation-swift.enum/insetApplicationFrame)

The application frame is reduced in size to compensate for overscan. Content drawn outside the application frame may be clipped.
