Refresh Rate Test FAQ
What is refresh rate (Hz)?
Refresh rate, measured in Hertz (Hz), is the number of times per second your monitor updates the image on the screen. A 60Hz monitor updates 60 times per second, while a 144Hz monitor updates 144 times. A higher refresh rate results in smoother, more fluid motion, which is why this refresh rate test is so important for gamers.
Why does my refresh rate test show a lower value than advertised?
There are several reasons this might happen. First, ensure you have set the correct refresh rate in your operating system's display settings (Windows or macOS). Second, make sure your graphics card drivers are up to date. Finally, ensure you are using a cable (like DisplayPort or a high-speed HDMI) that supports your monitor's maximum refresh rate. The UFO test accurately reflects what your system is currently outputting.
