Monitor vertical refresh rate setting in X.

[Sthu Deus <sthu.deus@gmail.com>]

Good day.

I can not set a desired V-frequency for a Samsung CRT monitor (an old
one). - As far as I understand from its own menu, it supports
resolution 800x600@85 Hz, then 1024x768@85 Hz and 1024x768@70 Hz.

I specify in xorg.conf to use:

resolution 1024x768
VertRefresh 85.0

then X-server uses 800x600@85 Hz mode,

if

resolution 1024x768
VertRefresh 70.0-85.0

then X-server uses 1024x768@70 Hz mode.

How I can make it using 1024x768@85 Hz mode?


Thank You for Your time.
