HZ Tool

HZ Tool is a tool that allows Windows users to manually set the refresh rate for all resolutions supported by their graphics cards.

Basic interface

The UI is small, and is packed with tick boxes and drop-down menus. The user can set the default refresh rate on each resolution in part, or it can configure one of the default refresh rates from the program's INI templates. The latter ones can be accessed via two buttons below the resolution lists, while a third lets you add your own custom refresh rates.

Comprehensive features

Users can customize their own refresh rates manually by selecting their current graphics card driver and the bit depth values which come in 8-, 16-, 24-, and 32-bit standards. Afterward, users can change the resolution and set it as default, together with the supported afferent refresh rate.
More advanced options are available in the program's main window. Users can set some basic monitor settings, like the maximum accepted resolution, horizontal and vertical refresh rates, and so on.
This tool is built to offer a more pleasant experience in gaming environments. It boosts your refresh rate at the maximum limit of your monitor, but only if the graphics card allows it. Obviously, this refresh rate helps the eyes a bit more and provide a much smoother experience in action packed games.

Conclusion

HZ Tool is an application that helps you boost your graphics card performance way beyond what your current driver has to offer. It gives you the freedom to set whatever refresh rates and resolutions you want, but first you have to make sure that both the graphics card and your monitor can handle it.
However, if they can, then your gaming experiences is great and images flow much smoother. You won't suffer from nausea or headaches when choosing to stay in front of your monitor for a long time.
