To properly display the download process of the Window 10 IoT Core operating system on Raspberry Pi, you must be known to be acceptable for frame rate and screen resolution of monitor. They come from somewhere and most likely when you get an EDID of connected monitor. From different types of platforms in Windows 10 IoT Core can be used as a Remote Machine and installed UWP applications in Visual Studio 2019.

Most commonly used for a single monitor

DisplayInformation displayInfo = DisplayInformation.GetForCurrentView();

As a result, it is possible to obtain such an introduction

CurrentOrientation Landscape Windows.Graphics.Display.DisplayOrientations
DiagonalSizeInInches null double?
LogicalDpi 96 float
NativeOrientation Landscape Windows.Graphics.Display.DisplayOrientations
RawDpiX 0 float
RawDpiY 0 float
RawPixelsPerViewPixel 1 double
ResolutionScale Scale100Percent Windows.Graphics.Display.ResolutionScale
ScreenHeightInRawPixels 768 uint
ScreenWidthInRawPixels 1360 uint
StereoEnabled false bool
Static members
AutoRotationPreferences None Windows.Graphics.Display.DisplayOrientations..

ScreenWidthInRawPixels, ScreenHeightInRawPixels are most likely used for established video mode. In more detail about the monitor in the Raspberry Pi 3 and Windows 10 IoT Core monitor is presented as "Generic Non-PnP Monitor", and EDID is not read on I2C. Magic MSMonitorClass is outside of UWP application platform of Windows 10 IoT Core.

MSMonitorClass is very useful for desktops ( Win32, C#, C++ )


The following code example retrieves the EDID blocks of any display as raw 128 bit arrays.


static void Main(string[] args)
ManagementClass mc = new ManagementClass(string.Format(@"\{0}\root\wmi:WmiMonitorDescriptorMethods", Environment.MachineName));

foreach (ManagementObject mo in mc.GetInstances()) //Do this for each connected monitor  
    for (int i = 0; i < 256; i++)  
        ManagementBaseObject inParams = mo.GetMethodParameters("WmiGetMonitorRawEEdidV1Block");  
        inParams["BlockId"] = i;   

        ManagementBaseObject outParams = null;  
            outParams = mo.InvokeMethod("WmiGetMonitorRawEEdidV1Block", inParams, null);  
            Console.Out.WriteLine("Returned a block of type {0}, having a content of type {1} ",  
                              outParams["BlockType"], outParams["BlockContent"].GetType());  
        catch { break; } //No more EDID blocks  


Another way to get monitor and multiple monitor info in Windows 10 and in Windows 10 IoT Core

String monitorSelector = DisplayMonitor.GetDeviceSelector();  

IAsyncOperation < DeviceInformationCollection> deviceSelection;  

deviceSelection = DeviceInformation.FindAllAsync(monitorSelector);  

AsyncStatus stat = deviceSelection.Status;  

// Canceled, Error
if ( stat == AsyncStatus.Completed )
if ( stat == AsyncStatus.Started )
while ( (stat = deviceSelection.Status) != AsyncStatus.Completed )

DeviceInformationCollection deviceCollection = deviceSelection.GetResults();  

foreach ( DeviceInformation device in deviceCollection )  
    String id = device.Id;  

    IAsyncOperation<Windows.Devices.Display.DisplayMonitor> display;  

    display = DisplayMonitor.FromInterfaceIdAsync(id);  

    /*AsyncStatus*/ stat = display.Status;  

// Canceled, Error
if ( stat == AsyncStatus.Completed)
if ( stat == AsyncStatus.Started )
while ((stat = display.Status) != AsyncStatus.Completed)

    DisplayMonitor monitor = display.GetResults();  

    float x = monitor.RawDpiX;  
    float y = monitor.RawDpiY;  

Properties from monitor EDID - "DisplayName", "PhysicalSizeInInches", "RawDpiX", "RawDpiY" are not real in Windows 10 IoT Core and
Raspberry Pi 3B but screen properties "NativeResolutionInRawPixels", "Height", "Width" are here correct

    Native View To inspect the native object, enable native code debugging.

With same microcomputer and monitor Raspberry Pi OS command "tvservice" gives data from monitor EDID and dumps full EDID.

Windows 10 IoT Core for Intel SoC's ( MinnowBoard/MAX (x64)) gives correct results as in desktops.
