Lenovo Legion Slim 5 Gen 9 AMD Ryzen 7 8745HS Display Driver Fix Windows 11

The display driver on your Lenovo Legion Slim 5 Gen 9 AMD Ryzen 7 8745HS crashes during gaming or produces a black screen followed by “Display driver stopped responding and has recovered.” Both AMD and NVIDIA drivers must be correctly installed and version-matched for stable display output on the Legion Slim 5 Gen 9 AMD hybrid graphics configuration.

This guide covers AMD and NVIDIA driver updates, Display Driver Uninstaller clean installation, and Lenovo Vantage GPU mode settings for the Lenovo Legion Slim 5 Gen 9 AMD Ryzen 7 8745HS in Windows 11.

“Legion Slim 5 Gen 9 AMD display driver crashed every hour of gaming. Lenovo Vantage had both AMD and NVIDIA updates. Installed AMD first, restarted, then NVIDIA. Driver crashes stopped completely.” – Hafiz Azran, game developer from Cyberjaya

Why Display Driver Crashes on Legion Slim 5 Gen 9 AMD

The Lenovo Legion Slim 5 Gen 9 AMD uses AMD Hybrid Optimus – AMD Radeon iGPU handles display output while NVIDIA GPU renders game frames. Both driver stacks must be version-compatible for the frame handoff between NVIDIA renderer and AMD display path to work without TDR (Timeout Detection and Recovery) events. If Windows Update installs a newer NVIDIA driver while the AMD driver remains older (or vice versa), the version mismatch in the hybrid display pipeline causes driver crashes during GPU load transitions.

• AMD and NVIDIA driver version mismatch in hybrid Optimus display stack
• NVIDIA driver TDR during gaming due to power limit mismatch in Legion Slim 5 Gen 9 chassis
• Generic Windows Update driver replacing Lenovo-qualified version for either GPU
• Previous driver installation not fully cleaned – old registry entries conflicting with new driver

Fix 1 – Update Both GPU Drivers via Lenovo Vantage

Open Lenovo Vantage and go to System Update. Install all available AMD Radeon and NVIDIA GeForce driver updates together. Restart after both are installed. Installing both drivers from the same Lenovo Vantage update cycle ensures version compatibility in the AMD Optimus hybrid stack. Lenovo validates AMD and NVIDIA driver version pairs specifically for the Legion Slim 5 Gen 9 AMD hardware configuration, preventing the version mismatch that causes TDR crashes during hybrid display path frame handoffs.

Fix 2 – Clean Install with DDU in Safe Mode

Boot to Safe Mode and run Display Driver Uninstaller. In DDU, select GPU and choose Clean and do NOT restart. Without restarting, also select the second GPU (if DDU allows both AMD and NVIDIA) and clean it. Restart. Go immediately to Lenovo Vantage – install AMD Radeon driver first – restart – then install NVIDIA driver. This order ensures the AMD display driver initializes the Optimus display path before NVIDIA registers as the rendering GPU, reducing Optimus stack initialization conflicts that cause TDR crashes after normal driver updates.

Enable Discrete GPU Mode for Gaming

Open Lenovo Vantage and find Hybrid Mode or GPU Mode setting. Switch to Discrete GPU Only mode and restart. Discrete GPU mode bypasses the AMD Optimus display path entirely, routing frames directly from NVIDIA to the panel. This eliminates the inter-GPU frame handoff that is the primary source of TDR crashes on hybrid platforms. Gaming performance also improves 10-15 percent without the AMD display processing overhead. Switch back to Hybrid mode for battery-saving non-gaming use.

Fix 3 – Reduce NVIDIA TGP in Lenovo Vantage

Open Lenovo Vantage and switch performance mode to Balance instead of Performance. Balance mode reduces the NVIDIA RTX TGP, lowering the peak power draw during gaming. On the Legion Slim 5 Gen 9 AMD slim chassis, the NVIDIA GPU at maximum TGP sometimes exceeds the power delivery budget shared with the AMD Ryzen 7 8745HS under combined CPU+GPU load, causing power transients that trigger NVIDIA TDR. Reduced NVIDIA TGP in Balance mode eliminates these power delivery TDR events.

Fix 4 – Update Legion Slim 5 Gen 9 BIOS

Go to Lenovo Vantage System Update or Lenovo Support and install the latest BIOS for Legion Slim 5 Gen 9 AMD. BIOS updates include AMD AGESA firmware and power delivery configuration updates that improve GPU TDR stability on the Ryzen 7 8745HS platform. Updated BIOS also includes Lenovo-specific power limit tables for the RTX GPU that match the slim chassis thermal design, reducing the frequency of power delivery events that trigger display driver TDR during sustained gaming.

Frequently Asked Questions

How do I fix display driver on Lenovo Legion Slim 5 Gen 9 AMD Ryzen 7 8745HS?

Update AMD and NVIDIA drivers via Lenovo Vantage together. DDU clean install in Safe Mode with AMD-first reinstall for persistent crashes.

Why does the display driver crash on Lenovo Legion Slim 5 Gen 9?

AMD/NVIDIA Optimus driver version mismatch or power delivery TDR. Update both drivers via Lenovo Vantage and reduce NVIDIA TGP with Balance mode.

Does Lenovo Legion Slim 5 Gen 9 AMD have a MUX switch?

Yes – Hybrid Mode switch in Lenovo Vantage. Discrete GPU mode eliminates AMD Optimus overhead for 10-15 percent gaming performance improvement.

What GPU is in Lenovo Legion Slim 5 Gen 9 AMD Ryzen 7 8745HS?

NVIDIA RTX 4060 or RTX 4070 Laptop GPU depending on configuration. Check Device Manager or Lenovo Vantage for exact model.

Conclusion

Lenovo Legion Slim 5 Gen 9 AMD Ryzen 7 8745HS display driver crashes in Windows 11 are resolved by updating both AMD and NVIDIA drivers together via Lenovo Vantage to ensure version compatibility in the hybrid Optimus stack. DDU clean installation in Safe Mode followed by AMD-first reinstall resolves persistent TDR crashes from old driver remnants. Enabling Discrete GPU mode bypasses the hybrid display path entirely for crash-free gaming. BIOS update improves power delivery stability for the NVIDIA GPU under combined CPU+GPU load.
