Thanks in advance! :)

system_profiler SPDisplaysDataType | grep Resolution

Will get you your resolution. You can pop this into a script for a custom
extension attribute.

Still some work needed on your part for the script, but this gets you down
to where you want to look for the display(s) resolution(s)

Thanks Lance,

Google is your friend...

Here's the command to pull the current resolution of monitor(s):

system_profiler SPDisplaysDataType | awk -F: '/Resolution/ {print $2}'

I guess I'll need to cobble together the Extension Attributes...one moment while I roll up my sleeves...

This did the trick:

---------------------------------
#!/bin/sh
echo "<result>/usr/sbin/system_profiler SPDisplaysDataType | awk -F: '/Resolution/ {print $2}'</result>"
---------------------------------

Thanks,
Don

The only problem with grep is that it can be too broad, and it can grab anything and everything that has the string Resolution in it. If you are running dual displays or hooked up to a projector when it runs this may cause issue. Of course I have not tested it, but for example if I did a grep for connections using port 548 it may grab these ports on a network connection:

1548
33548
153248

Since the string 548 is in all of those you may get wonky results.

just FYI

Then just use a regular expression to narrow down your results to what you need..

Tweaked this extension attribute a bit so it will also pull windows machines screen resolutions as well. Just paste this in the VBScript field after doing the above for the mac:

Set objWMIService = GetObject("Winmgmts:. ootcimv2") Set colItems = objWMIService.ExecQuery("Select * From Win32_DesktopMonitor where DeviceID = 'DesktopMonitor1'",,0) For Each objItem in colItems intHorizontal = objItem.ScreenWidth intVertical = objItem.ScreenHeight Next
WScript.Echo "<result>" &amp; intHorizontal&amp;"x"&amp;intVertical &amp; "</result>"
