First, if you are only running one resolution, specify:

Good idea, I'll give it a try.
In your monitor section in your config file to specify a vertical refresh
of between 95 and 100HZ. This should be sufficient by itself.
You can also specify modelines with the correct pixel clock. You would
need to google for one of the mode line generators and use it to generate
a modeline for your monitor with the correct horizontal, vertical and
pixel clocks.

Frankly, setting a refresh rate of 100 is useless. I have extremely
sensitive eyes and I can not notice a refresh above 82Hz or so.
I have good eye-sight and there is a noticeable difference between 85hz and
100. My monitor isn't that great though, so perhaps it would be less
noticeable with a higher-quality display.
Second, a high refresh rate reduces the clarity of the image on your
screen. Problems such as ghosting appear. Poor quality cables, long
cables, high resolution or a low quality monitor make the problem worse.
Your refresh rate should be a few Hz higher than the highest refresh rate
at which you stop noticing flicker. If you can still see a flicker at 75Hz
then run your monitor at 80 or 85.
My ViewSonic P815 was capable of 120Hz at 1600x1200 (I believe. Been a
long time since I used a CRT). I never ran it above 85Hz because it simply
wasn't necessary.
If you want a 100% rock solid image, then get an LCD.
Thanks for the info!
