144Hz test
Find out whether your screen is actually showing 144 frames per second. Frame time at 144 Hz is 6.94 ms.

Top lane updates at 60 fps, bottom at 144 fps (capped at whatever your display actually shows). If both look the same, you are not getting 144 Hz. For a detailed graph see the full refresh rate test.
Who has 144 Hz displays
The most common gaming monitor refresh rate at 1080p and 1440p.
Getting 144 Hz working
- Pick 144 Hz in the OS. Windows 11: Settings → System → Display → Advanced display → Choose a refresh rate. macOS: System Settings → Displays → Refresh Rate.
- Cable and port: DisplayPort 1.2+ is the safest choice. HDMI 2.0 commonly reaches 1440p at 144 Hz; HDMI 1.4 often tops out lower.
- In games, set the in-game refresh rate (if offered) to 144 Hz and make sure the frame rate cap isn't lower.
A very common setup mistake is leaving the monitor at 60 Hz in Windows Settings → Display → Advanced display after plugging it in.

Questions people ask
How do I know if my monitor is running at 144 Hz?
Open this page and wait a few seconds. If the estimate settles near 144 Hz, the browser is receiving 144 frames per second from your display. You can also check Windows Settings → System → Display → Advanced display, or macOS System Settings → Displays → Refresh Rate.
Why does my 144 Hz monitor show a lower number?
A very common setup mistake is leaving the monitor at 60 Hz in Windows Settings → Display → Advanced display after plugging it in. Also check that the cable goes into the graphics card rather than the motherboard, battery saver is off on laptops, and hardware acceleration is on in the browser.
What cable do I need for 144 Hz?
DisplayPort 1.2+ is the safest choice. HDMI 2.0 commonly reaches 1440p at 144 Hz; HDMI 1.4 often tops out lower. Exact limits depend on resolution, colour depth and whether the monitor uses Display Stream Compression (DSC), so check your monitor's manual.
Is a browser refresh rate test accurate?
It estimates refresh from requestAnimationFrame timing, which browsers align to the display. It reliably separates 60, 120, 144 and 240 Hz, but it is not a lab measurement, and variable refresh (G-Sync, FreeSync, ProMotion) can move it.
