get resolution of 2nd monitor via script

[Matt Lind]

Hey all.
I've been trying to figure out how to get the resolution of the
user's monitors via script (JScript) as I need to write some tools that
place/resize PPGs in specific ways on the screen. Using a WMIService
query, I've been able to get the primary monitor's configuration, but I
cannot find a way to get the 2nd monitor's info. Unfortunately, I
cannot assume the 2nd monitor is the same as the 1st. Anybody have any
ideas?

I'd like to keep my code simple and homogenous, which means a solution
using JScript and doesn't require installation of any 3rd party tools.

thanks,

Matt


PS - here's how I get the primary monitor's info:

// Jscript
/*
GetMonitorResolution();

function GetMonitorResolution()
{
var wbemFlagReturnImmediately = 0x10;

var Mode = wbemFlagReturnImmediately;
var Query = "Select * from Win32_VideoController";
var oWMIService = GetObject( "winmgmts:\\\\.\\root\\cimv2" );
var oCollection = oWMIService.ExecQuery( Query, "WQL", Mode );

var oItems = new Enumerator( oCollection );

for ( ; !oItems.atEnd(); oItems.moveNext() ) {

var oItem = oItems.item();

// dump info
LogMessage( "Resolution [x,y]: " +
oItem.CurrentHorizontalResolution + ", " +
oItem.CurrentVerticalResolution );
}

return;
}
*/

I can't test it at the moment but i've a feeling you should be in Win32_DeskTopMonitor

GetMonitorResolution();

function GetMonitorResolution()
{
       var wbemFlagReturnImmediately = 0x10;

       var Mode        = wbemFlagReturnImmediately;

       var Query       = "Select * from Win32_DeskTopMonitor";

       var oWMIService = GetObject( "winmgmts:\\\\.\\root\\cimv2" );
       var oCollection = oWMIService.ExecQuery( Query, "WQL", Mode );

       var oItems = new Enumerator( oCollection );
       for ( ; !oItems.atEnd(); oItems.moveNext() ) {
               var oItem = oItems.item();
               // dump info
               LogMessage( "Resolution [x,y]: " +

oItem.ScreenWidth + ", " +
oItem.ScreenHeight );
       }

       return;
}

Win32_VideoController is the actual physical gfx card

As i said, i can't test it at the moment unless someone sends me a nice 2nd monitor (will accept cash equivalent) :D

I tried everything with the word "Display", "Video", "Monitor", and "Desktop" in it.  Seems like no matter what I query I always get the primary monitor, and no additional information for the secondary monitor.

Have you tried using some of the flags in your query ?

select * from win32_DesktopMonitor where Availability = 3 //is on


any reason you can't write the plug in c# ?

I have now.  No change in result unfortunately. :-(

I don't use C#.

 

I write 95% of my tools in JScript because it comes with XSI, is cross platform, and doesn't require additional software to be installed to do most things.  For the other 5%, typically performance related stuff, I use C/C++.

:(

i wasn't trying to sway you to the dark side ;)

after a quick google there seemed to be lots of people with exactly the same problem as you. other than trawling the registry i wouldn't know how to solve this
bugger. In C# I'd just use the Screen namespace and be done with it.

Maybe someone else has some experience/insight into the magical world of wmi

I've got nothing against C#.  Just never had a need for it.

 

Yes, I've seen a lot people have the same problem.  Would it be easier to write a C++ plugin to grab the display details through OpenGL or some other Graphics API?

I would have thought bog standard GDI calls would do the trick rather than messing around in ogl.

It definitely breaks your simplicity of staying with a portable language but as a temporary stopgap ( until a jscript soloution is found) i'd say it's the only way to keep some sanity :)

There is nothing in OpenGL about monitor resolution, it's platform independent.
