Refresh rate has become one of the main specifications of mobile phones, both in the mid-range and in the upper ranges. 90 and 120 Hz are here to stay, and even budget proposals already benefit from panels that deliver a smoother experience.
However, high refresh rates are often adaptive, so we cannot take advantage of it all the time. We will show you how to know in real time how many hertz your mobile screen is refreshed, which will also help you understand how this technology works.
Display Checker
Display Checker is a completely free app with very little advertising (it only has a bottom banner) that shows us information on the screen. Resolution, supported technologies, density and, what interests us the most in this tutorial: the refresh rate it supports and the values in which it oscillates
This application shows in real time how many hertz the screen of your mobile is refreshing
The magic of this app is that we can turn on real-time warning to see how refreshing our screen is. The hertz at which the panel is operating will be displayed digitally, and you can even choose where this warning will be displayed on the screen.
As usual, screens activate maximum refresh rate when touched, and their value decreases when we view static content. Depending on the mobile, this can go down to plus or minus Hertz, which makes it an interesting application to understand how our screen works in real time.
