Gateway EV700 CRT Monitor Refresh Rates
Ok, I'm using a Gateway EV700 monitor at the moment. My preferred refresh rate is 60 Hz, I like the clarity, but the way my xorg.conf is configured only allows 85 Hz, which is murder on my eyes after 30 minutes or so. I was told I need to know the Horizsync and Vertrefresh values for my monitor and changing those would fix it, but I have been unsuccessful in finding any documentation on it, and I do not have the user manual because the monitor was a hand-me-down. Can anybody here help me out and tell me what I need to do to my xorg.conf file to get it down to 60 Hz, or at least something lower than 85? I know 60 works b/c it's what Windows uses.

Xorg
Oh yeah, here are the contents of my xorg.conf file:
Code:

# used to render fonts.

# Option "Xleds" "1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
# Option "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# Or if you just want both to be control, use:
# Option "XkbOptions" "ctrl:nocaps"

You obviously like headaches  72 Hz is the minimum ergonomic refresh rate. Anything lower will give you headaches and will make you tired quicker. But OK, that's your problem.
Change the vertrefresh from 50.0 - 120.0 to 50.0 - 60.0 should do the trick. If the system insists on higher than 60 after the modification, please come back. As you're using an nvidia driver, there might be a setting in the device section that needs to be added.
PS Don't forget to restart the xserver after the modification.
