esta es facil!!, aki te pongo la funcion k yo utilizo siempre: comprobado k funciona:
'CAMBIO DE RESOLUCION
Private Declare Function EnumDisplaySettings Lib "user32" Alias "EnumDisplaySettingsA" (ByVal lpszDeviceName As Long, ByVal iModeNum As Long, lpDevMode As Any) As Boolean

Dim DevM As DEVMODE
Function CambiaResolucion(BitPorPixel As Integer, Ancho As Integer, Alto As Integer) As Boolean
'Parámetros :
'BitPorPixel : Nº de bits de color
' 4 - 16 colores, 8 - 256 colores
' 16 - 65.000 colores, 32 - 16 M de colores
'Ancho : Nº de pixels de ancho
'Alto : Nº de pixels de alto
Dim a&
a = EnumDisplaySettings(0&, 0&, DevM)
DevM.dmFields = DM_PELSWIDTH Or DM_PELSHEIGHT
DevM.dmBitsPerPel = BitPorPixel
DevM.dmPelsWidth = Ancho
DevM.dmPelsHeight = Alto
a = ChangeDisplaySettings(DevM, 0)
If a = 0 Then
CambiaResolucion = True
Else
CambiaResolucion = False
End If
End Function
La llamada es cantidad de facil, te la pongo
Dim a&
'Llamada a la función para cambiar la resolución
a = CambiaResolucion(16 - 65#, 800, 600)
y ya esta la resolucion cambiada
TalegoZ gente!!
