Setting Monitor Refresh Frequency (Red Hat 7.2)
Hi !
I have Red Hat 7.2. I want to set the Refresh Frequency of my monitor
according to the monitor
recommendation (1024 x 768, 75 Hz). This frequency works perfectly on
my Win200o installation.
I tried to use Xconfigurator and xvidtune programs, but unfortunaely
it seems that I can't adjust
the refresh frequency from there. Than I openned XF86Config file. In
"Monitor" section I have
a range of frequencies : VertRefresh 50.0-120.0 and the list of
different modes.
My question is: how I update the XF86Config file in order to set the
specific refresh frequency number ?
By the way, in Windows we have only one refresh frequency paramater to
configure. Is it the vertical frequency ?
Thanks a lot in Advance.
Jean.
