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).
