Constant Screen Flickering - i5-10210U UHD Graphics - Safe Mode Fixes It

[Zoned]

Hello Intel Community,

I'm experiencing persistent screen flickering on my HP EliteBook 830 G7 and need help diagnosing this Intel UHD Graphics issue.

System Configuration:

• CPU: Intel Core i5-10210U

• Graphics: Intel UHD Graphics (10th Generation)

• OS: Windows 10 Home 64-bit (22H2)

• RAM: 8GB

• Laptop: HP EliteBook 830 G7

Problem Description:
Constant screen flickering that:

• Affects both the internal laptop display AND external monitors

• Begins immediately when Windows loads

• Does NOT occur in Windows Safe Mode

• Is present during all normal Windows use

Key Diagnostic Information:

1. Safe Mode Test: Flickering completely stops in Windows Safe Mode

2. Dual Display Test: Both internal and external monitors flicker simultaneously

3. Clean Boot Test: Flickering persists even with minimal startup

4. BIOS Display: No flickering during POST/BIOS screens

Troubleshooting Already Attempted:
✓ Clean driver reinstall using DDU (Display Driver Uninstaller)
✓ Tested multiple driver versions (latest and older stable releases)
✓ Disabled all Windows display power-saving features
✓ Adjusted refresh rates and scaling settings
✓ Performed full hardware power cycle/reset
✓ Updated all system drivers (chipset, etc.)
✓ Ran HP hardware diagnostics (all tests pass)

Current Driver Details:

• Driver Version: [Your current version - check in Intel Graphics Command Center]

• Driver Date: [Date]

• Graphics Controller: Intel UHD Graphics (Comet Lake)

Specific Questions:

1. Is this a known issue with 10th Gen Intel UHD Graphics power management?

2. What specific Safe Mode differences could explain the flickering stop?

3. Are there recommended registry tweaks or Intel-specific settings to try?

4. Which diagnostic logs should I collect to help identify the root cause?

Additional Information:

• DxDiag report is available

• Event Viewer doesn't show consistent display-related errors

• Temperatures are normal (CPU: 45-60°C during issue)

• Issue is reproducible 100% of the time
