; Function Name:    _ChangeScreenRes()
; Description:      Changes the current screen geometry, colour and refresh rate.
; Version:          1.0.0.1
; Parameter(s):     $i_Width - Width of the desktop screen in pixels. (horizontal resolution)
;                   $i_Height - Height of the desktop screen in pixels. (vertical resolution)
;                   $i_BitsPP - Depth of the desktop screen in bits per pixel.
;                   $i_RefreshRate - Refresh rate of the desktop screen in hertz.
; Requirement(s):   AutoIt Beta > 3.1
; Return Value(s):  On Success - Screen is adjusted, @ERROR = 0

#cs - example
#include <ChangeResolution.au3>

$iWidth = 1024
$iHeight = 768
$iBitsPP = 32
$iRefreshRate = 60

If @error Then
    MsgBox(262160, "ERROR", "Unable to change screen - check parameters")
EndIf

Format for the UDF is as follows:
#include <ChangeResolution.au3>
_ChangeScreenRes( [Width [, Height [, BitsPerPixel [, RefreshRate]]]] )

Do this:

  • Take the code I gave you. Save it as "resolution.au3" and place it in your "include" folder in your AutoIt directory. The AutoIt directory is located under Program files.
  • Make a new script file in SciTe (DO NOT OVERWRITE RESOLUTION.AU3)
  • Put in the following code:
    #include<resolution.au3>
    _changescreenres(1280,768,32,60)
  • save the file as "1024.au3"
  • press F5 and that will run it.
