Display Details

This feature provides detailed information about the display devices, including primary display attributes and a collection of all connected displays.

Overview

The Display Details feature of the SiticoneSystemInfo control exposes public properties that deliver comprehensive data regarding the system's display devices. This includes information about the primary display—such as its name, driver version, video memory, and current resolution—as well as a read‑only list of all available displays. This feature is ideal for applications that require dynamic screen configuration, multi-monitor management, or visual diagnostics in WinForms.


Key Points

Aspect
Details

Exposed Properties

PrimaryDisplayName, PrimaryDisplayDriver, PrimaryDisplayMemory, PrimaryDisplayResolution, Displays

Data Sources

Data is collected via WMI queries (e.g., Win32_VideoController) which retrieve display details from the system

Data Integrity

Read‑only properties and collections ensure that display data remains consistent during runtime

Integration

Easily bind these properties to UI components such as labels, data grids, or charts to visually present display configurations and status


Best Practices

Practice
Description

Use asynchronous refresh

Always call the asynchronous RefreshAsync() method to update display details without freezing the UI.

Bind to UI elements

Bind the primary display properties to UI labels and the Displays collection to grids or lists for dynamic and real‑time monitoring.

Validate display data

Check for valid or non‑empty values when accessing display properties to prevent runtime errors.

Update the UI on the main thread

When updating UI components with display data, ensure updates occur on the UI thread to avoid cross-thread exceptions.


Common Pitfalls

Pitfall
Description
Recommendation

Data retrieval delays

Display information may require additional time for accurate retrieval, especially on systems with multiple monitors.

Allow a short initialization delay or verify that asynchronous refresh has completed before accessing display properties.

Incomplete display data

If no display device is detected or if WMI queries fail, properties may return empty or default values.

Implement fallback logic or provide default messages when display data is unavailable.

UI thread blocking

Synchronous operations while retrieving display details can freeze the UI.

Use asynchronous refresh methods to ensure the UI remains responsive during data updates.

Incorrect data binding

Misconfigured data bindings can result in improper display of information in the UI.

Validate the bound data and ensure proper data conversion before assigning it to UI components.


Usage Scenarios

Scenario
Description

Primary Display Monitoring

Retrieve and display primary display attributes (name, driver, memory, resolution) on a dashboard for monitoring screen performance.

Multi-Monitor Management

Bind the Displays collection to a grid or list to show all connected monitors, enabling multi-display configuration or diagnostics.

Visual Diagnostics

Use display details in diagnostic tools to verify that display devices are functioning correctly and meet configuration standards.


Real Life Usage Scenarios

Scenario
Description

IT Support and Troubleshooting

Integrate display information into an IT support tool that identifies and logs display configurations, helping diagnose issues with multi-monitor setups.

Digital Signage Management

Use the feature in a digital signage application to dynamically monitor and adjust display settings across multiple screens.

Compliance and Asset Auditing

Employ the control to verify that display devices conform to corporate hardware standards during periodic audits.


Troubleshooting Tips

Tip
Description
Recommendation

Validate data availability

Sometimes, display properties may return empty values if the system fails to detect a monitor.

Check for null or default values and implement fallback text or logic to notify the user.

Ensure asynchronous updates

UI freezing issues can occur if display data is retrieved synchronously.

Always use asynchronous methods (e.g., RefreshAsync) to update display data without impacting UI responsiveness.

Confirm proper data binding

Incorrect data binding can cause display information to be shown incorrectly.

Verify that data bindings to UI elements are correctly configured and that data conversion (if needed) is handled properly.

Monitor for WMI exceptions

WMI queries might occasionally throw exceptions if the system restricts access to display information.

Use try-catch blocks around data retrieval and log any exceptions without exposing sensitive details.


Code Examples & Integration Demos

Example 1: Displaying Primary Display Information

Description: Bind primary display properties to labels to show the display name, driver version, memory, and resolution.

// In your Form_Load event
private async void MainForm_Load(object sender, EventArgs e)
{
    await systemInfoControl.RefreshAsync();

    lblPrimaryDisplayName.Text = $"Display: {systemInfoControl.PrimaryDisplayName}";
    lblDisplayDriver.Text = $"Driver: {systemInfoControl.PrimaryDisplayDriver}";
    lblDisplayMemory.Text = $"Memory: {systemInfoControl.PrimaryDisplayMemory / (1024.0 * 1024):F2} MB";
    lblDisplayResolution.Text = $"Resolution: {systemInfoControl.PrimaryDisplayResolution}";
}

Example 2: Binding All Displays to a DataGridView

Description: Bind the Displays collection to a DataGridView to list all connected display devices.

// In your Form_Load event or a dedicated method
private async void MainForm_Load(object sender, EventArgs e)
{
    await systemInfoControl.RefreshAsync();
    
    dataGridViewDisplays.DataSource = systemInfoControl.Displays.ToList();
}

Example 3: Updating a Monitor Configuration Panel

Description: Periodically refresh display information and update a panel that shows current display configurations.

// Timer event for periodic refresh (e.g., every 5 seconds)
private async void timer_Tick(object sender, EventArgs e)
{
    await systemInfoControl.RefreshAsync();
    panelMonitorConfiguration.Controls.Clear();
    
    // Create a label for each connected display
    foreach (var display in systemInfoControl.Displays)
    {
        Label lbl = new Label
        {
            Text = $"Name: {display.Name}, Resolution: {display.CurrentResolution}, Driver: {display.DriverVersion}",
            AutoSize = true,
            Margin = new Padding(5)
        };
        panelMonitorConfiguration.Controls.Add(lbl);
    }
}
