Screen flickering in Windows 11 can be frustrating, especially during work or media consumption. It often appears as brief flashes, rolling lines, or intermittent brightness changes. The good news is that most flickering issues can be resolved with a few targeted fixes. Here’s how to troubleshoot and fix screen flickering on Windows 11.

1. Update or Roll Back Your Graphics Driver

Graphics drivers are the most common cause of screen flickering.

Update the driver:

• Press Win X and select Device Manager.
• Expand Display adapters.
• Right-click your graphics driver (e.g., Intel, NVIDIA, AMD) and choose Update driver.
• Select Search automatically for drivers.

If Windows finds an update, install it and restart your PC.

Roll back the driver (if flickering started after an update):

• In Device Manager, right-click the graphics driver again.
• Choose Properties → Driver tab → Roll Back Driver.
• Follow the prompts and restart.

Tip: If Windows doesn’t offer a rollback option, the previous driver may not be saved. In that case, manually download an older stable version from the manufacturer’s website.

2. Disable Windows Snap and Transparency Effects

Some Windows 11 visual features can cause flickering, especially on older hardware.

Turn off transparency effects:

• Go to Settings → Personalization → Colors.
• Set Transparency effects to Off.

Disable Snap Assist animations:

• Go to Settings → System → Multitasking.
• Turn off Show suggestions when I snap a window and related options.

These changes reduce GPU load and may stop flickering during window resizing or snapping.

3. Check for Windows and App Updates

Microsoft often releases patches for display-related bugs.

• Go to Settings → Windows Update.
• Click Check for updates and install any available updates.
• Also, update apps like browsers (especially Chrome), which sometimes cause flickering due to GPU rendering.

If the issue started right after a feature update, consider waiting for a patch or using System Restore to revert to a stable point.

4. Adjust Display Refresh Rate

Mismatched refresh rates can cause flickering, especially on external monitors.

• Go to Settings → System → Display → Advanced display.
• Select your display and check Refresh rate.
• Try switching to a different rate (e.g., from 60 Hz to 75 Hz or vice versa).
• Pick the one marked as “Recommended” if available.

5. Disable Full-Screen Optimization (for apps/games)

This setting can interfere with full-screen applications.

• Right-click the app’s shortcut or executable (.exe).
• Go to Properties → Compatibility tab.
• Check Disable fullscreen optimizations.
• Click Apply.

Test the app to see if flickering stops.

6. Scan for Malware and Problematic Software

Some third-party apps (especially screen recording or overlay software like Discord, GeForce Experience, or RGB control tools) can cause flickering.

• Open Task Manager (Ctrl Shift Esc) and look for high GPU usage or suspicious processes.
• Temporarily disable startup apps via Task Manager → Startup tab.
• Run a malware scan using Windows Security or a trusted antivirus.

7. Hardware and Cable Checks

If you're using an external monitor:

• Try a different HDMI/DisplayPort cable.
• Connect to a different port on your PC or monitor.
• Test the monitor with another device to rule out hardware issues.

For laptops:

• Check if flickering happens only on battery vs. plugged in (could indicate power management issues).
• Try an external monitor — if it works fine, the issue may be with the laptop’s internal display or ribbon cable.

Bottom line: Start with driver updates and visual effects, then move to system and hardware checks. Most flickering issues in Windows 11 are software-related and fixable without professional help.

Basically, it’s not complex — just methodical.
