The Testing Experience
Understand Refresh Behavior Through Your Browser
Browser-based refresh rate testing relies on frame timing information produced while a webpage is rendered. It can help estimate refresh-related behavior, although browser and system conditions may affect the result.
Browser Rendering
A browser schedules and renders visual frames. Their timing provides information that can be used to estimate refresh behavior.
Timing Observations
Frame intervals help explain the relationship between rendering frequency and refresh rate estimates.
Result Interpretation
Compare observations with configured display settings and consider factors that might explain differences.
Understand the Numbers
What Do Hz and Frame Intervals Mean?
Refresh rate describes how frequently a display can update its image. A higher refresh rate corresponds to a shorter theoretical interval between display updates.
Refresh Interval (ms) = 1000 ÷ Refresh Rate (Hz)
These are theoretical intervals. They are not measurements of application FPS, input latency, or pixel response time.
Compare Refresh Rates
60Hz vs 75Hz vs 120Hz vs 144Hz vs 165Hz vs 240Hz
Comparing theoretical intervals helps explain why higher refresh rates can support smoother-looking motion when the rest of the system delivers frames appropriately.
| Refresh Rate | Theoretical Interval | Relative Interval |
|---|---|---|
| 60Hz | 16.67 ms | |
| 75Hz | 13.33 ms | |
| 120Hz | 8.33 ms | |
| 144Hz | 6.94 ms | |
| 165Hz | 6.06 ms | |
| 240Hz | 4.17 ms |
These calculated values do not guarantee actual FPS, response time, input latency, or perceived smoothness.
Real-World Applications
When Is a Refresh Rate Test Useful?

Checking a Monitor Configuration
Relate a reported reading to the refresh rate selected in your operating system.
Learning About Gaming Displays
Explore how 120Hz, 144Hz, and 240Hz relate to motion presentation in games.
Comparing Laptop Screens
Learn about common laptop refresh rates and factors that affect observed behavior.
Understanding Multiple Displays
Learn why multi-monitor setups add considerations without implying automatic monitor detection.
Investigating Unexpected Readings
Explore why an observation may differ from the configured refresh rate.
Learning Display Technology
Understand refresh rate concepts and their relationship to frame timing.
Get Started
How to Run a Refresh Rate Test
Use the existing testing experience and compare the observation with your display configuration.
- 01
Open RefreshRateTestly
Visit the homepage to access the refresh rate testing experience.
- 02
Check Display Settings
Review the refresh rate selected in your operating system.
- 03

Use the homepage tool and allow the browser to perform its timing observations.
- 04
Review the Reading
Compare the observation with your setting and consider browser or system factors.
Interpreting Results
What Your Refresh Rate Reading Can Tell You
A browser-based reading can provide useful information, but it should be interpreted alongside your display configuration and system conditions.
What It Can Help You Understand
- Browser-observed refresh behavior.
- Whether a reading appears consistent with a configured setting.
- The relationship between frequency and frame timing.
- Why system conditions can influence observations.
What It Cannot Guarantee
- Direct hardware-level panel measurement.
- Verification of a monitor's advertised maximum.
- Complete diagnosis of display hardware problems.
- Identical readings across browsers and systems.
- Complete input-latency, response-time, or motion-clarity assessment.
Refresh rate is one part of the visual experience. Frame rate, pixel response, synchronization, system performance, and content also influence perceived smoothness.
Practical Guidance
Tips for More Consistent Refresh Rate Observations
Browser-based measurements can vary. These practical steps may help reduce avoidable differences between observations without guaranteeing perfect accuracy.
Check Your Display Settings
Confirm the selected refresh rate in your operating system.
Reduce Heavy Background Activity
Close unnecessary resource-intensive applications when practical.
Use an Updated Browser
Modern browsers may provide more consistent rendering behavior.
Consider Power Settings
Laptop power-saving modes can affect display and rendering behavior.
Pay Attention to Multiple Displays
Connected monitors may use different refresh rates or affect browser timing.
Repeat the Observation
Multiple readings can add useful context when results fluctuate.

Common Questions
Refresh Rate Test Features FAQs
Find answers to common questions about refresh rate testing, display settings, and browser-based measurements.
View All FAQsA browser-based refresh rate test uses frame timing information to estimate or observe refresh-related behavior. Browser and system conditions can influence the result.
Refresh rate is the number of times a display updates its image per second, measured in Hz. FPS is the number of frames generated by an application or graphics system per second.
Browser-based testing can be used with displays at different configured rates, but the observation depends on the browser, system, and display environment. It does not guarantee verification of an advertised maximum.
Browser scheduling, system load, power settings, variable refresh rate behavior, and other rendering conditions can cause fluctuations.
A higher refresh rate can support smoother-looking motion, but frame delivery, pixel response, synchronization, and other factors also matter.
No. Browser-based timing information provides useful observations, but it is not a complete hardware diagnostic.
At 120Hz, the theoretical interval between refreshes is approximately 8.33 milliseconds.
