Symptoms & Diagnosis
The AMD Radeon RX 580 remains a popular choice for budget gaming, but screen flickering is a documented issue that can disrupt your workflow or gaming sessions. This problem typically manifests as rapid brightness changes, horizontal lines, or the screen momentarily turning black.
To diagnose the issue, determine if the flickering occurs only during specific tasks. If it happens during gaming, it may be a power or thermal issue. If it occurs on the desktop, it is likely a driver conflict or a faulty display cable. Identifying these patterns is the first step toward a permanent fix.
Troubleshooting Guide
Resolving RX 580 flickering usually involves a mix of software calibration and hardware checks. Start with the most common software solutions before moving to hardware adjustments.
1. Clean Driver Installation
Old or corrupted driver files often cause signal instability. Use the Display Driver Uninstaller (DDU) to completely wipe existing drivers in Windows Safe Mode before installing the latest stable version from the AMD website.

While FreeSync is designed to smooth out gameplay, it can cause flickering on monitors with poor “sync range” compatibility. Navigate to the Radeon Software settings and toggle FreeSync to ‘Off’. Additionally, disable Virtual Super Resolution (VSR) as it can strain the card’s scaling engine.
3. Configuration Comparison Table
Use the table below to prioritize your troubleshooting steps based on the symptoms you are experiencing.
| Symptom | Primary Fix | Success Rate |
|---|---|---|
| Intermittent Black Screen | Replace HDMI/DP Cable (Certified) | High |
| Flickering in Browser | Disable Hardware Acceleration | Medium |
| Lines during Gaming | Increase Power Limit (+5-10%) | Moderate |
4. Check Hardware and Power Supply
The RX 580 is power-hungry. Ensure your Power Supply Unit (PSU) is at least 500W and that the 8-pin power connector is seated firmly. Often, a “daisy-chained” power cable causes voltage drops that result in visual artifacts.
Prevention
To prevent future flickering, maintain a stable thermal environment. The RX 580 tends to run hot; using the Radeon Software to set a more aggressive fan curve can prevent thermal-induced signal drops.
Always keep your Windows OS updated and avoid using “Beta” optional drivers unless they specifically address a bug you are facing. Finally, ensure your monitor firmware is up to date, as manufacturers often release patches for sync-related flickering issues.
