Visual Refresh Rate Indicator
- What is my refresh rate? This test measures your browser FPS and estimates your screen Hz.
- Stuck at 60Hz? Enable 120/144Hz in OS settings and check your cable or adapter support.
- Mobile supported? Yes—works on iPhone ProMotion and Android high-refresh-rate displays.
- Is this FPS or Hz? In most cases browser FPS is capped by display refresh rate, so FPS is a practical Hz estimate.
Understanding Refresh Rate
What is Screen Refresh Rate?
The refresh rate of a display, measured in Hertz (Hz), is the number of times per second the screen hardware refreshes its image. A higher number usually means smoother motion.
Why Does It Matter?
Smoother Motion
A high refresh rate results in more fluid motion, especially in games and scrolling.
Reduced Motion Blur
With more frames shown per second, moving objects appear sharper and easier to follow.
Improved Response
Higher refresh rates can reduce perceived input lag and make interaction feel faster.
Common Refresh Rates
| Rate | Description |
|---|---|
| 60Hz | The standard rate for office work, everyday browsing, and most video playback. |
| 90Hz / 120Hz | Common on modern phones and tablets with noticeably smoother scrolling and animations. |
| 144Hz & Higher | Popular with gamers and high-performance desktop monitors. |
Frequently Asked Questions
What does Hz mean for a monitor?
Hz (Hertz) represents cycles per second. For a monitor, it indicates how many times the screen updates the image every second.
Why does my 144Hz monitor show 60Hz?
You may need to change your display refresh-rate setting in the operating system, and you should also confirm that the cable and port support the higher refresh rate.
Does HDMI support 144Hz?
Yes, but it depends on the HDMI version and resolution. Older HDMI versions may limit you to lower refresh rates at higher resolutions.
How to enable 120Hz on iPhone or Android?
On supported phones, look in display settings for refresh rate, motion smoothness, or related adaptive display options.
Is this an FPS Test?
Technically yes. The browser-rendered FPS often tracks your display refresh rate because modern browsers usually sync rendering with the monitor refresh cycle.
