I would agree with what Richard says. However, it is possible to get these
refresh rates on most average/budget modern monitors and video cards
without having to buy something special. It really annoys me when the
settings have not been changed to take advantage of this as I can see flicker
below about 72Hz and find it difficult to work for long on a PC that hasn't
been set up to take advantage of this feature.
In Windows 98 there are several ways to alter the refresh rate. Look in the
system tray at the bottom right corner of the screen. If you have a picture of
a monitor with a ruler (at least that's what I think it is!) right click on it and
choose Adjust Display Properties. If you don't have this Icon, right click
somewhere on an empty area of the desktop and choose Properties.
Then choose the settings tab and go to Advanced - here's where things may
vary in different windows versions! Then choose the adapter tab and you
should find the refresh rate setting box.This will only work properly if youR
monitor is correctly identified to Windows, so you may need to check that
setting as well (go to the monitor tab).
You may then need to finish off by changing some of the centering / size
properties on the setup menu built in to the monitor.

Of course, TFT screens completely sidestep the issue of refresh rate
but they are expensive. Especially on a size for size basis - a 17"
monitor has about a 15.9" viewable area. The former can be bought for
less than £200 whereas a 15" TFT is about £600.
