### 3.5 Settings
The Settings screen allows you to configure the device's behavior. There are a few settings you can adjust:
- **White Sleep Screen**: Whether to use the white screen or black (inverted) default sleep screen
- **Sleep Screen**: Which sleep screen to display when the device sleeps, options are:
- "Dark" (default) - The default dark sleep screen
- "Light" - The same default sleep screen, on a white background
- "Custom" - Custom images from the SD card, see [3.6 Sleep Screen](#36-sleep-screen) below for more information
- "Cover" - The book cover image (Note: this is experimental and may not work as expected)
- **Extra Paragraph Spacing**: If enabled, vertical space will be added between paragraphs in the book, if disabled,
paragraphs will not have vertical space between them, but will have first word indentation.
- **Short Power Button Click**: Whether to trigger the power button on a short press or a long press.
### 3.6 Sleep Screen
You can customize the sleep screen by placing custom images in specific locations on the SD card:
- **Single Image:** Place a file named `sleep.bmp` in the root directory.
- **Multiple Images:** Create a `sleep` directory in the root of the SD card and place any number of `.bmp` images
inside. If images are found in this directory, they will take priority over the `sleep.png` file, and one will be
randomly selected each time the device sleeps.
> [!NOTE]
> You'll need to set the **Sleep Screen** setting to **Custom** in order to use these images.
> [!TIP]
> For best results:
> - Use uncompressed BMP files with 24-bit color depth
> - Use a resolution of 480x800 pixels to match the device's screen resolution.
