Here is some add-on reference information that I've found that others
may find helpful for setting the default sync rates on their monitors.
Note: the info is primarily for older monitors, but many folks (me
included) still run older CRT's & sometimes it's hard to find
documentation/info on sync rates for those monitors.
Hope this helps:
