75Hz test
Find out whether your screen is actually showing 75 frames per second. Frame time at 75 Hz is 13.33 ms.

Top lane updates at 60 fps, bottom at 75 fps (capped at whatever your display actually shows). If both look the same, you are not getting 75 Hz. For a detailed graph see the full refresh rate test.
Who has 75 Hz displays
Budget office and entry-level gaming monitors, often with FreeSync.
Getting 75 Hz working
- Pick 75 Hz in the OS. Windows 11: Settings → System → Display → Advanced display → Choose a refresh rate. macOS: System Settings → Displays → Refresh Rate.
- Cable and port: HDMI 1.4 or newer and DisplayPort handle 75 Hz at 1080p; 1440p at 75 Hz is usually fine on HDMI 2.0 or DisplayPort.
- In games, set the in-game refresh rate (if offered) to 75 Hz and make sure the frame rate cap isn't lower.
Some 75 Hz monitors only offer 75 Hz over one input. Check the manual if you're stuck at 60.

Questions people ask
How do I know if my monitor is running at 75 Hz?
Open this page and wait a few seconds. If the estimate settles near 75 Hz, the browser is receiving 75 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 75 Hz monitor show a lower number?
Some 75 Hz monitors only offer 75 Hz over one input. Check the manual if you're stuck at 60. 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 75 Hz?
HDMI 1.4 or newer and DisplayPort handle 75 Hz at 1080p; 1440p at 75 Hz is usually fine on HDMI 2.0 or DisplayPort. 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.
