# Screen

### Get Screen Size

{% code lineNumbers="true" %}

```javascript
const { getScreenSize } = require('positron.js/screen');

const { width, height } = getScreenSize();

if (width && height) {
  console.log(`Your screen resolution is: ${width}x${height}`);
} else {
  console.log("Could not detect screen resolution.");
}
```

{% endcode %}

Retrieves the current horizontal and vertical resolution of the primary display.

* **Returns:** `Object`
  * `width` `(number)`: The horizontal resolution in pixels. Returns `0` if undetected or upon failure.
  * `height` `(number)`: The vertical resolution in pixels. Returns `0` if undetected or upon failure.

### Platform Behavior

The function adapts its underlying command based on `process.platform`:

| Operating System | Command Used                            | Method                                                               |
| ---------------- | --------------------------------------- | -------------------------------------------------------------------- |
| `win32`          | `Get-CimInstance Win32_VideoController` | Queries WMI via PowerShell for active video controller dimensions.   |
| `darwin`         | `system_profiler SPDisplaysDataType`    | Queries Apple System Profiler and parses display resolution strings. |

> Note: On multi-monitor setups, this utility generally returns the resolution of the primary display device.
