HZ Tool is a freeware tool for Windows 95/98 that lets you set
the refreshrate for all resolutions, including the ones that
Windows normally don't let you use. You can also change resolution
It was programmed by me, Stefan Berglind, in 1998, because the
drivers for my graphics card didn't allow me to easily set the
refreshrates for games. It works in all programs that uses Windows
routines to change resolution, for example:
OpenGL games, i.e. Quake3 and Unreal
Note that most games runs faster with a higher refreshrate if
v-sync is enabled, which it is by default. It's also much more
pleasant to your eyes looking at 120 Hz instead of 60 or 75
Hz. With Hz Tool you can also edit the properties of your monitor,
which allows you to get the most out of it in refreshrates and
that all graphics cards and drivers do not allow you to change
the refreshrate or use unusual resolutions. The program gives
you freedom to set whatever refreshrates and resolutions you
want, but you have to make sure that both the graphics card
and your monitor can handle it. Use precaution!
