I would like to find the refresh rate of my monitor. Apple has some
sample code that seems like it is supposed to do this (the VBL sample)
but a) it doesn't seem to work (prints out "hz = 0") and b) the code
isn't commented so I am not sure what is wrong.
Anyway, the VBL sample code makes me think it should be possible to
get the refresh rate without trying to use CGDisplayBeamPosition and
trying to time it. However, I haven't been able to get the sample code
to work and I haven't been able to find any documentation. Can someone
give me a clue?
If you are on a LCD monitor, you will get zero since there is no good
way to describe the the refresh process there (apparently, see the Mac
Games Dev list archives for exhaustive discussions about this topic).
