Symptoms
- Only 60Hz is available in Display Settings
- Monitor is rated for 120Hz, 144Hz, or higher but it's not listed
- Higher refresh rate worked before on the same setup
- Option appears when using a different cable or port
Likely causes
- CommonWrong cable type or version for the desired refresh rateOlder HDMI cables and even some DisplayPort cables can't carry higher refresh rates at higher resolutions.
- CommonConnected to the wrong port on the graphics cardSome GPUs limit high refresh rate output to specific ports.
- CommonOutdated graphics driverDriver updates frequently add or fix refresh rate detection.
- PossibleMonitor's high refresh rate mode not enabled in its own menuSome monitors require enabling an 'Overclock' or high refresh mode in their on-screen settings.
What to do
- Check the monitor's manual or specs to confirm which port (HDMI vs DisplayPort) supports its maximum refresh rate.
- Switch to DisplayPort if currently using HDMI, since DisplayPort more reliably supports higher refresh rates on many monitors.
- Update the graphics driver to the latest version from NVIDIA, AMD, or Intel.
- Open the monitor's on-screen menu and look for an 'Overclock,' 'OC Mode,' or refresh-rate-related setting to enable.
- In the graphics driver's control panel, look for a custom resolution/refresh rate tool to manually add the desired refresh rate if it's not listed automatically.
- Lower the resolution slightly and check if a higher refresh rate becomes available, since some cable/port combinations can't handle both at maximum settings simultaneously.

When to call a pro
If a proper cable, correct port, and updated driver still don't unlock the advertised refresh rate, contact the monitor manufacturer's support, since it may be a defective unit.
