ATI Radeon RefreshRate Fix: Quick Solutions for Screen Flicker and Stuttering
Quick checklist (try in order)
- Restart and reconnect — reboot PC, unplug and replug the display cable and power to the monitor.
- Check cable and port — use a DisplayPort or HDMI cable rated for your target refresh rate (e.g., DisplayPort 1.2+ or HDMI 2.0+). Try a different cable or port.
- Set Windows display refresh rate
- Windows ⁄11: Settings > System > Display > Advanced display > Choose the correct refresh rate.
- Update or roll back GPU driver
- Install the latest official AMD driver (Adrenalin) for your GPU. If the issue began after an update, roll back to the previous driver.
- Use AMD Radeon Settings / Adrenalin
- Open Radeon Software > Display tab > ensure custom resolutions/refresh rates are correct. Disable unnecessary features like Radeon Enhanced Sync to test.
- Check monitor OSD and modes — ensure the monitor is set to the correct input mode (e.g., DP 1.2, 144Hz mode) and disable any overdrive or dynamic refresh features temporarily.
- Disable conflicting software — close third-party utilities (overclocking, frame-rate limiters, screen recording) to rule out conflicts.
- Check power and performance settings — Windows Power Plan: set to High Performance; Radeon Software: switch to Performance profile.
- Test with another monitor or PC — verify whether the problem follows the monitor or the GPU/PC.
- Reset settings or clean install drivers
- Use DDU (Display Driver Uninstaller) in Safe Mode to remove drivers, then reinstall the latest AMD Adrenalin driver.
If flicker/stutter persists — targeted checks
- Intermittent flicker with DisplayPort: try a different DP cable and set the monitor’s DP mode to 1.⁄1.⁄1.4 as appropriate.
- Stuttering at high refresh rates: verify GPU can consistently render frames; enable V-Sync or a frame limiter to test if frame pacing is the issue.
- Driver regression: search for a known bug for your exact GPU model and driver version; use an earlier stable driver if needed.
- Custom resolution/refresh: remove custom modes and use native monitor settings to rule out EDID/custom mode issues.
Useful commands/tools
- AMD Adrenalin Software (driver & settings UI)
- DDU (Display Driver Uninstaller) — for clean driver removal
- Windows dxdiag and Event Viewer — check for hardware or driver errors
When to seek repair or replacement
- Persistent flicker across cables and PCs → likely monitor hardware fault.
- Artifacts, crashes, or instability across multiple displays and clean driver installs → GPU hardware issue.
