WmiGetMonitorRawEEdidV1Block method of the WmiMonitorDescriptorMethods class
The WmiGetMonitorRawEEdidV1Block method gets the raw data for a specified Video Electronics Standard Association (VESA) Enhanced Extended Display Identification Data (E-EDID) structure that defines optimal settings for configuring a monitor.
Syntax
uint32 WmiGetMonitorRawEEdidV1Block(
[in] uint8 BlockId,
[out] uint8 BlockType,
[out] uint8 BlockContent[]
);
Parameters
-
BlockId [in]
-
The data block identity.
-
BlockType [out]
-
Type of data block. The following table lists possible return values.
Value Meaning - 0 (0x0)
Uninitialized - 1 (0x1)
EDID base block - 2 (0x2)
EDID block map - 255 (0xFF)
Other -
BlockContent [out]
-
A 128-byte array that contains the raw block content.
Return value
Returns zero (0) to indicate success. Any other number indicates an error. For more information about error codes, see WMI Error Constants or WbemErrorEnum.
Examples
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;
try
{
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
}
}
}
