Lenovo Legion 5 Pro Gen 8 AMD Ryzen 7 7745HX Screen Flickering Fix

The Lenovo Legion 5 Pro Gen 8 is a gaming laptop equipped with an AMD Ryzen 7 7745HX processor and a high-refresh-rate display. Screen flickering — rapid flashing, horizontal lines, or intermittent black flashes during gaming or general use — is a serious issue that can make the laptop unusable and may indicate a driver or hardware problem.

This guide walks through the most reliable fixes for screen flickering on the Lenovo Legion 5 Pro Gen 8.

What Causes Screen Flickering

Screen flickering on the Legion 5 Pro Gen 8 typically falls into one of these categories:

• Outdated or incompatible AMD Radeon or NVIDIA driver
• Display refresh rate set higher than a connected application supports
• Variable refresh rate (FreeSync) conflict with certain games
• Loose display cable connection (hardware)
• Windows desktop composition conflict with certain software

Step-by-Step Fixes

Fix 1: Update the GPU Driver

An outdated AMD or NVIDIA driver is the most common software cause of flickering:

1. Open AMD Software: Adrenalin Edition or GeForce Experience.
2. Check for driver updates and install the latest version.
3. For AMD: choose a Custom Install and perform a Factory Reset during installation.
4. Restart and test whether flickering persists.

Fix 2: Disable FreeSync and Variable Refresh Rate

FreeSync can cause flickering at very low or very high frame rates that fall outside the supported range:

1. Open AMD Software: Adrenalin Edition > Display.
2. Toggle AMD FreeSync Premium off.
3. Also disable Variable Refresh Rate in Windows Display settings under Advanced display.
4. Test whether flickering stops during gaming.

Fix 3: Lower the Display Refresh Rate

Some display panels and driver combinations produce flickering at their maximum rated refresh rate:

1. Right-click the desktop and select Display settings > Advanced display.
2. Reduce from 165Hz to 144Hz, or from 144Hz to 120Hz.
3. Test at the lower rate. If flickering stops, the driver or panel has a compatibility issue at the maximum rate that a driver update may resolve.

“A clean AMD driver install with factory reset fixed my screen flickering completely. The old driver had some residual settings that conflicted with the Legion panel at 165Hz.”

Fix 4: Check Task Manager for the Flickering Pattern

Open Task Manager and watch whether it flickers along with the screen. If everything flickers including Task Manager, the cause is a driver or hardware issue. If only the desktop flickers but Task Manager is stable, the cause is likely an incompatible application — uninstall recently added software to identify it.

Fix 5: Update BIOS via Lenovo Vantage

Lenovo BIOS updates sometimes include display controller fixes. Open Lenovo Vantage, go to System Update, and install all available updates including BIOS. After restarting, test display stability at the maximum refresh rate.
