Change resolution to the recomended

[Delai]

Hi i want to change the resolution display to the recomended, but it does not work. here is my script:

#include <GuiConstantsEx.au3>
#include <WindowsConstants.au3>
Opt("WinTitleMatchMode", 2)
$Title = "Resolución"
RunWait("RunDll32.exe shell32.dll,Control_RunDLL desk.cpl")
WinActivate($Title)
sleep (500)
$Title2= WinGetTitle ( $Title,  "Pantalla" )
$Combo = ControlCommand($Title2,"","DirectUIHWND4","FindString", 'recomendado')
ControlCommand($Title2,"","DirectUIHWND4","SetCurrentSelection", $Combo)

Did you try this GaryFrost example ?

It works well, but any suggest please how to change the resolution to (recomended) instead of 1024x768, i means as in the resolutions display, usually there is one recomended which i don´t know automatically until i enter. i want to select that resolution without to know which is it?
