Why verify your Hz?
Many gamers buy 144Hz or 240Hz monitors but forget to enable high refresh rates in Windows Display Settings or Nvidia/AMD Control Panels. If this tool shows "60Hz" on a gaming monitor, you are likely losing a significant competitive advantage.
How it works
This tool uses the requestAnimationFrame API to measure exactly how often your browser
tries to paint a new frame. By averaging these intervals over hundreds of cycles, we can determine your
hardware refresh rate with high accuracy.
How to Enable High Refresh Rates (144Hz, 240Hz, 360Hz)
If your high refresh rate monitor is showing up as 60Hz, follow these steps to unlock its full potential:
- 1. Windows Display Settings: Right-click on your desktop -> select Display settings -> click Advanced display settings -> choose your high refresh rate from the Refresh rate dropdown.
- 2. NVIDIA Control Panel: Right-click on your desktop -> open NVIDIA Control Panel -> under "Display", click Change resolution -> scroll down and select your native resolution under the "PC" category, and select the highest refresh rate.
- 3. AMD Radeon Software: Open Radeon Software -> click the settings gear -> select the Display tab -> ensure FreeSync is enabled and the refresh rate matches your panel specifications.
Common Reasons Your Monitor is Stuck at 60Hz
- Incompatible Cables: Older HDMI cables (versions below 1.4 or 2.0) are bandwidth-limited and cannot support high refresh rates at high resolutions. Use a high-quality DisplayPort (DP 1.4+) cable for gaming monitors.
- Incorrect Ports: Some monitors only support high refresh rates over DisplayPort or specific HDMI ports (e.g. HDMI 2.0/2.1). Refer to your monitor's manual.
- Browser Constraints: On laptops with dual graphics cards (integrated Intel/AMD + dedicated NVIDIA/AMD), ensure your web browser is running on the dedicated GPU in Windows Graphics Settings.
MONITOR REFRESH RATE FAQ
What is frame skipping and how do I detect it?
Frame skipping is when a monitor drops frames instead of displaying them, which looks like stuttering even at high refresh rates. You can test for this by taking a long exposure photograph of a moving checkerboard pattern; if there are gaps in the path of the blocks, the monitor is skipping frames.
Why does this tool show a fluctuating refresh rate?
Fluctuations occur due to browser performance hiccups, open tabs, background CPU load, or active G-Sync/FreeSync syncing variables. Close other tabs and active programs to get a solid, stable reading.
