Yes, the `powercfg /query SCHEME_CURRENT SUB_VIDEO VIDEOIDLE` command specifically queries the power settings for the display idle timeout. This setting determines how long the display will remain on when the system is idle before it turns off.

### Querying Other Power Settings

If you want to query different power settings, you need to use different subcategories and settings. Here are a few examples:

- **Display Timeout**:
  ```powershell
  powercfg /query SCHEME_CURRENT SUB_VIDEO VIDEOIDLE
  ```

- **Sleep Timeout**:
  ```powershell
  powercfg /query SCHEME_CURRENT SUB_SLEEP STANDBYIDLE
  ```

- **Hard Disk Timeout**:
  ```powershell
  powercfg /query SCHEME_CURRENT SUB_DISK DISKIDLE
  ```

- **Processor Power Management**:
  ```powershell
  powercfg /query SCHEME_CURRENT SUB_PROCESSOR PROCTHROTTLEMAX
  ```

### Example: Querying Sleep Timeout

Here is an example of how to query and convert the sleep timeout values similarly to how you did with the display timeout:

```powershell
function Get-SleepTimeout {
    [CmdletBinding()]
    param ()

    # Query the active power scheme settings for AC and DC sleep timeouts
    $ACSleepTimeout = powercfg /query SCHEME_CURRENT SUB_SLEEP STANDBYIDLE | Select-String -Pattern 'Power Setting Index' | ForEach-Object { $_.Line -split '\s+' } | Select-Object -Last 1
    $DCSleepTimeout = powercfg /query SCHEME_CURRENT SUB_SLEEP STANDBYIDLE | Select-String -Pattern 'Power Setting Index' | ForEach-Object { $_.Line -split '\s+' } | Select-Object -First 1

    # Convert extracted values to integers
    $ACSleepTimeout = [int]$ACSleepTimeout
    $DCSleepTimeout = [int]$DCSleepTimeout

    # Create a PSCustomObject with the extracted timeouts
    $TimeoutObject = [PSCustomObject]@{
        ACSleepTimeout = $ACSleepTimeout
        DCSleepTimeout = $DCSleepTimeout
    }

    return $TimeoutObject
}

# Example usage
$SleepTimeout = Get-SleepTimeout
Write-Output "ACSleepTimeout: $($SleepTimeout.ACSleepTimeout)"
Write-Output "DCSleepTimeout: $($SleepTimeout.DCSleepTimeout)"
```

This script defines a function `Get-SleepTimeout` that queries the sleep timeouts for both AC and DC power states, converts the values to integers, and returns them as a custom object. You can modify this approach for other power settings by changing the `SUB_*` and setting names in the `powercfg` query command.
