I've found an entry "Refresh rate" on the regedit tool:
HKEY_LOCAL_MACHINE > Config > 001 > Display > Settings
or
HKEY_CURRENT_CONFIG > Display > Settings
I search how to use that with Pure...

DON'T WRITE IN THE REGESTRY WITHOUT KNOWING WHAT IT IS!
Also under diffrent Systems (Win98,Win95,XP,2000) and diffrent Drivers may diffrent Regestry-keys. So search a other methode.

I don't want to write on it, just see the value of the key "Refresh rate".

This seems to be another way to do it (note this is getting more than just frequency, hence the length of the code!)... it also returns the *current* display mode, so you don't have to parse each available mode in turn...
Code: Select all
#ENUM_CURRENT_SETTINGS = -1
#ENUM_REGISTRY_SETTINGS = -2
DefType.DEVMODE dm
EnumDisplaySettings_ (#NULL, #ENUM_CURRENT_SETTINGS, @dm)
m$ = "Width: " + Str (dm\dmPelsWidth) + Chr (10)
m$ + "Height: " + Str (dm\dmPelsHeight) + Chr (10)
m$ + "Depth: " + Str (dm\dmBitsPerPel) + Chr (10)
m$ + "Frequency: " + Str (dm\dmDisplayFrequency) ; FREQUENCY!
MessageRequester ("Display mode information...", m$, #MB_ICONINFORMATION)
