A free program for Android, by Chainfire.

TVHZ is an application that allows you to change the display’s refresh rate, which can be really useful for gamers. It’s not an app that changes the hardware’s refresh rate, but it can help you to improve the performance of your device and save battery. This is done by changing the display’s refresh rate, which is done by the OS and not by the hardware.

In order for this app to work, you need a compatible TV or monitor.

This was created to be used on devices that are based on the Android operating system.
