Display Refresh Rate
Keywords: current refresh rate display
Question:
Just wondering if there is a way to get the current refresh rate of the display like 60Hz, 75Hz, 100Hz etc...Answer:
You might try poking around in the registry around this key:HKLM\System\CurrentControlSet\Services\Class\Display.On a Win98 box it appears to be:
HKLM\System\CurrentControlSet\Services\Class\Display\0000\MODES\16\1024,768[RefreshRate].It may differ depending on the video hardware.
WMI might be able to give you some info. Give this code a try:
Locator = ObjectOpen("WbemScripting.SWbemLocator")
Service = Locator.ConnectServer()
Security = Service.Security_
Security.ImpersonationLevel = 3
Class = "Win32_DisplayConfiguration"
Instance = Service.InstancesOf(Class)
hEnum = ObjectCollectionOpen(Instance)
While 1
Obj = ObjectCollectionNext(hEnum)
If Obj == 0 Then Break
Message(Obj.Description, StrCat("Display Frequency"," = ",Obj.DisplayFrequency))
EndWhile
ObjectCollectionClose(hEnum)
ObjectClose(Instance)
ObjectClose(Security)
ObjectClose(Service)
ObjectClose(Locator)
Exit
