If you’re experiencing issues with the 120Hz ProMotion display not working on your iPhone or iPad, you’re not alone. This feature offers smoother scrolling, more responsive touch, and an overall enhanced visual experience. Sometimes, due to software glitches, settings misconfigurations, or compatibility issues, the 120Hz refresh rate may not activate or function correctly. This guide provides clear, step-by-step instructions to troubleshoot and fix the problem, ensuring you enjoy the full benefits of your device’s display capabilities. Before starting, make sure your device supports ProMotion (iPhone 13 Pro, 14 Pro, iPad Pro models, etc.) and that your device’s software is up to date.
What You’ll Need
- iPhone or iPad running iOS 15.0 or later (preferably latest version)
- Stable internet connection for software updates
- Device fully charged or connected to power
Step-by-Step
- Verify Device Compatibility: Ensure your iPhone or iPad model supports ProMotion technology. For iPhones, this includes iPhone 13 Pro and newer; for iPads, iPad Pro models from 2018 onward support 120Hz.
- Check if ProMotion is Enabled: Open Settings > Display & Brightness. Look for an option called ProMotion or Refresh Rate. If available, ensure it is turned on. Note that on some devices, this setting is automatic and cannot be toggled.
- Update Your Device: Go to Settings > General > Software Update. Download and install the latest iOS or iPadOS version if available. Updates often fix bugs related to display features.
- Restart Your Device: Power off your device completely, then turn it back on. Sometimes, a simple restart resets display settings and resolves temporary glitches.
- Disable and Re-enable Auto-Refresh Rate (if applicable): In Settings > Display & Brightness, toggle the Auto-Lock or related settings to see if the refresh rate activates properly. On some devices, the refresh rate adjusts automatically based on usage.
- Reset All Settings: If the feature still isn’t working, go to Settings > General > Reset > Reset All Settings. This resets system settings without deleting your data and can fix misconfigurations affecting the display.
- Test the Display: Open a high-refresh-rate compatible app or game, or navigate through smooth scrolling content like Safari or social media feeds. If you notice smoother motion, the feature is working.
- Contact Apple Support: If none of the above steps work, your device might have a hardware issue or need professional diagnostics. Contact Apple Support or visit an authorized service provider.
Common Mistakes
- Assuming all devices support 120Hz without verifying compatibility.
- Ignoring software updates, which may contain bug fixes for display issues.
- Disabling Auto-Refresh Rate settings if they are automatically managed by the system.
- Not restarting the device after changing settings or updates, which can prevent changes from taking effect.
- Overlooking the importance of fully charging the device before troubleshooting, especially if battery-related performance issues are involved.
Tips
- Keep your device’s software up to date to benefit from the latest features and bug fixes.
- Use high-refresh-rate-compatible apps and content to verify the feature’s functionality.
- Ensure your device is not in Low Power Mode, as this can limit performance and display capabilities. Turn it off in Settings > Battery.
- If you have multiple display settings, experiment with turning off other display features like True Tone or Night Mode temporarily to see if they interfere with ProMotion.
- Regularly restart your device to clear temporary glitches that may affect display performance.
Troubleshooting
If the above steps don’t resolve the issue, consider the following troubleshooting tips:
- Perform a Force Restart: On iPhone 13 or newer, press and quickly release volume up, then volume down, then press and hold the side button until the Apple logo appears. On iPads with Face ID, press volume up, then volume down, then hold the top button. This can clear minor glitches affecting the display.
- Check for App Compatibility: Some apps may not support 120Hz or may disable it. Test with native apps like Safari or Apple’s built-in apps, which are optimized for ProMotion.
- Reset Settings: As a last resort, reset all settings (see step 6 above). This can resolve configuration conflicts without erasing your data.
- Restore Your Device: Backup your device and perform a factory reset via iTunes or Finder. Set up as new to rule out software corruption. If the problem persists after restore, it may be hardware-related.
- Seek Professional Help: Visit an Apple Store or authorized repair center for hardware diagnostics, especially if your device is out of warranty or exhibits signs of physical damage.
