Monitor FPS Test - Check Display FPS and Hz Online
Use this monitor FPS test to check whether your display path is delivering smooth browser motion. It measures monitor-facing FPS, estimates the visible refresh cadence, and helps diagnose common 60Hz caps on external monitors, laptop panels, docks, cables, and browser settings.

Stability
A monitor FPS test checks the browser animation cadence visible on your display. It cannot force a monitor into a higher refresh mode if the operating system, cable, dock, or browser is capped.
Monitor troubleshooting
A monitor FPS test is useful when the specification and the real result disagree
Many monitors advertise 120Hz, 144Hz, 165Hz, or 240Hz, but the actual browser result may stay near 60 FPS. That does not always mean the monitor is broken. It can mean the display mode is set incorrectly, the external display cable is limited, the dock is using a slower output mode, or the browser is being throttled by battery and power settings.
System refresh setting
Confirm the operating system is set to the target refresh rate, not the default 60Hz mode.
Cable and dock limits
Some HDMI cables, adapters, and docks can force an external monitor into a lower refresh mode.
Browser and power mode
Energy saver, inactive tabs, and low-power laptop settings can cap animation timing.
Fullscreen comparison
Use the same browser window size or fullscreen mode when comparing monitor FPS test results.
Refresh-rate guide
Compare the monitor FPS result with common refresh targets
The goal is not to chase the highest number blindly. The useful question is whether the monitor FPS test result matches the refresh setting you expect. A 60Hz office monitor should sit near 60 FPS. A gaming monitor set to 144Hz should usually measure near 144 FPS when the browser is active and the device is not throttled.
60Hz baseline
Common office display and default external monitor mode.
120Hz smooth
Popular target for gaming monitors, phones, and newer laptops.
144Hz high refresh
Common gaming monitor setting that should feel cleaner than 60Hz.
240Hz reference
Very high-refresh displays need a strong full display path.
External monitor checks
If your external monitor FPS test result is stuck at 60, check the cable type, adapter, dock, USB-C display mode, and monitor on-screen menu. Some displays support high refresh only on specific ports or specific resolutions. Lowering resolution temporarily can also reveal whether the cable bandwidth is the problem.
Laptop monitor checks
Laptops often change refresh behavior on battery. Some systems switch to 60Hz in low power mode, while others use dynamic refresh rate. Run the monitor FPS test plugged in and on battery to see whether power mode changes frame pacing or estimated Hz.
Why monitor FPS can differ from hardware claims
A monitor box may advertise a maximum refresh rate, but the computer still has to select that mode and send frames through a compatible path. Resolution, color depth, cable bandwidth, adapter quality, GPU output, and operating system settings can all change the final monitor FPS test result. That is why a browser-based check is helpful after setup changes: it shows the refresh behavior you are actually getting in the current desktop session, not only the best number printed in the specification sheet.
FAQ
Common questions about monitor FPS testing
Is a monitor FPS test the same as a refresh rate test?
It is closely related. The test measures browser frame timing and estimates the display cadence visible to the browser. A dedicated hardware refresh-rate tool may use different methods, but this page is useful for checking real browser motion on the monitor you are using.
Why does my 144Hz monitor test at 60 FPS?
The most common causes are a 60Hz system setting, limited cable or adapter, browser throttling, battery saver, inactive tab behavior, or an external dock that does not support the target refresh rate at your current resolution.
Can this test measure in-game FPS?
No. It measures the browser animation loop on your monitor. In-game FPS depends on the game engine, GPU, CPU, settings, and scene load. Use this monitor FPS test to check display smoothness and caps before running game-specific benchmarks.
Should I test with one monitor or multiple monitors?
Test the monitor you care about directly. Move the browser window to that display, keep it active, and run again. Multi-monitor setups can behave differently when displays use different refresh rates.
