Common Refresh Rate Problems

Many users experience these issues without realizing. Run a refresh rate test to diagnose problems:

  1. Wrong Cable Limitation: HDMI 1.4 cables cannot support 4K at high refresh rates. If you are using an older cable, you may be limited to 60Hz even on a capable monitor. Use DisplayPort 1.4 or HDMI 2.1 for best results. A refresh rate test reveals cable limitations.
  2. Operating System Override: Windows, macOS, and Linux may default to 60Hz even if your monitor supports higher. Always check your display settings after driver updates. A refresh rate test confirms OS settings.
  3. GPU Driver Settings: NVIDIA and AMD control panels have their own refresh rate settings that can override system defaults. Ensure your graphics driver is configured correctly. Run a refresh rate test to verify.
  4. Game-Specific Settings: Many games have their own refresh rate or frame rate limits. Check in-game settings to ensure they match your monitor's capabilities. A refresh rate test helps optimize game settings.
