Hi Paul,
Refresh rates vary by resolution (pixel count) on screen... ie are you
running at 1024x768 or 800x600 or ?  Generally, the higher the
resolution (pixel count) the lower the refresh rate so any question on
the subject must include resolution.

Some monitor manufacturers provide inf files for some monitors and the
easiest and safest solution to a situation like this is to install and
use them if they are available.  The light lines do inddeed resemble the
behavior of a monitor that is running just above what it can handle as a
refresh rate.

I fried an older monitor once pushing refresh rates so it is certainly
something to pay attention to.
