How to Determine the Current Screen's Dimensions in WPF

In multi-monitor environments, the primary screen may not always be the one in use or the one with the highest resolution. Therefore, it's essential to be able to retrieve the size of the current screen you're interested in.

WPF Method: Using SystemParameters

SystemParameters provides direct access to the dimensions of the primary screen:

double primaryScreenWidth = System.Windows.SystemParameters.PrimaryScreenWidth;
double primaryScreenHeight = System.Windows.SystemParameters.PrimaryScreenHeight;

Multi-Screen Support: Using WpfScreen Wrapper

For scenarios with multiple screens with varying resolutions, the WpfScreen class offers a more flexible approach:

private WpfScreen CurrentScreen
{
    get { return WpfScreen.GetScreenFrom(this); }
}

public double ScreenWidth => CurrentScreen.DeviceBounds.Width;
public double ScreenHeight => CurrentScreen.DeviceBounds.Height;

The WpfScreen class provides methods to:

• Get the dimensions of all active screens
• Get the screen associated with a specific window
• Determine if the current screen is the primary display

Using the Wrapper in XAML

The WpfScreen class can be used in XAML through attached properties:

<Window>
    <Window.AttachedProperties>
        <my:WpfScreenAttachedProperties.WpfScreen>
            <my:WpfScreen DeviceBounds="{Binding ElementName=myCtrl, Path=ScreenWidth, Mode=OneWay}"/>
        </my:WpfScreenAttachedProperties.WpfScreen>
    </Window.AttachedProperties>
    ...
</Window>
