Windows 10: What is "MaxHorizontalImageSize" and "MaxVerticalImageSize" using WmiMonitorBasicDisplayParams.

I have two displays connected and was able to read the below data.

[Disp1]:
DisplayTransferCharacteristic : 120
InstanceName : DISPLAY\JDI0000\4&ed57c9d&1&
MaxHorizontalImageSize : 32
MaxVerticalImageSize : 88

[Disp2]:
DisplayTransferCharacteristic : 120
InstanceName : DISPLAY\JDI0000\4&ed57c9d&1&
MaxHorizontalImageSize : 128
MaxVerticalImageSize : 224


Please help in knowing more about "MaxHorizontalImageSize" and "MaxVerticalImageSize". Resolution has been set to "1200 X 1920" in display settings.


Q1. Is these values["MaxHorizontalImageSize" and "MaxVerticalImageSize" ] shown should match the physical display size ? Why the values in "wmimonitorbasicdisplayparams" for MaxHorizontalImageSize and MaxVerticalImageSize are not reflecting or matching the physical size of the Display that is ~ 13 X 20 CM. ??


Q2. From where these values will be retrieved ?


Q3. What is the need of using "WmiMonitorBasicDisplayParams" ?

Q4. Why there is a change in value for both the displays.[Disp1 and Disp2]


Please help asap.

:)

 

Windows Powershell- Detect Docking Stations and attached monitors


You could use cmdlet Get-CimInstance:

Code:

Code:

Get-CimInstance -Namespace root\wmi -ClassName WmiMonitorBasicDisplayParams

Multiply the horizontal and vertical image size with 40 to get resolution in pixels. For example MaxHorizontalImageSize 48 / MaxVerticalImageSize 27 = 1920 * 1080 resolution.

More information about the monitors can be found with the following command:

Code:

Code:

Get-CimInstance win32_desktopmonitor

-- OR --
Code:

Code:

Get-CimInstance win32_videocontroller | select caption, CurrentHorizontalResolution, CurrentVerticalResolution

And, if needed, information about the GPU:

Code:

Code:

Get-CimInstance win32_videocontroller

 

Can Someone Help me Write a Script


Nus, this did not work for me but DonationCoder told me that a simple shortcut with the following as target
will "detect display" Hope someone else finds this and it is beneficial. Thank you so much for your time and effort., I don't know what I would do without all the help I receive from gurus such as yourself. I am really amazing how many people across the web give of themselves to assist strangers. Good will is alive and well in the computing world.

%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe -noprofile -executionpolicy bypass -Command "Get-CimInstance -Namespace root\wmi -ClassName WmiMonitorBasicDisplayParams | Out-Null"

edit 7/23/15 I forgot to add that this shortcut must be "run as administrator"

No, worries, that looks like a simpler method, heh.

I've got a script to set resolution, colour depth and refresh rate, so say if you need that.
