Lenovo Legion 7i Gen 8 Display Overclock Not Working Windows 11

The 240Hz display option is missing from Windows 11 Display settings on your Lenovo Legion 7i Gen 8 – only 60Hz or 165Hz is available, not 240Hz. Or you enabled 240Hz but it reverts to a lower rate after restart. This is a GPU mode and driver configuration issue on the Legion 7i Gen 8.

This guide covers GPU mode switching, NVIDIA driver update, and display settings to enable 240Hz on the Lenovo Legion 7i Gen 8 in Windows 11.

“My Legion 7i Gen 8 only showed 165Hz max in display settings. Expected 240Hz from the specs. Switching to Discrete GPU in Vantage made 240Hz appear immediately.” – Darwisyah, FPS gamer from Shah Alam

Why 240Hz Is Not Available on Lenovo Legion 7i Gen 8

The Legion 7i Gen 8 display runs at maximum refresh rate only when the NVIDIA GPU is in Discrete GPU mode. In Hybrid mode (NVIDIA Optimus), the display is driven through the Intel integrated GPU which has bandwidth limitations that prevent 2560×1600 at 240Hz. The 240Hz option disappears from Display settings until you switch to dGPU mode.

• GPU mode set to Hybrid (Optimus) – iGPU bandwidth limits display to 165Hz at 2560×1600
• NVIDIA driver version older than 522.25 missing 240Hz EDID profile for this display
• Display settings in Windows 11 not showing 240Hz option despite dGPU mode active
• Power plan set to Battery Saver limiting display performance

Fix 1 – Switch to Discrete GPU Mode in Lenovo Vantage

Open Lenovo Vantage, go to Device – My Device Settings – Display. Look for GPU Mode or look in the Power section. Change from Hybrid to Discrete GPU. A restart is required. After restart, right-click the desktop – Display settings – Advanced display – Choose a refresh rate and 240Hz should now be listed. Select it and confirm.

Fix 2 – Update NVIDIA Driver

Download the latest NVIDIA GeForce driver from Lenovo Support for Legion 7i Gen 8 or from nvidia.com/drivers. Versions 522.25 and later include updated EDID profiles for the Legion 7i Gen 8 QHD 240Hz display. Install with Custom – Clean installation to remove any older profile conflicts.

Display Refresh Rate in NVIDIA Control Panel

Open NVIDIA Control Panel (right-click desktop), go to Display – Change resolution. Select the Legion 7i Gen 8 display and verify 2560×1600 at 240Hz is listed. If not, click Customize and add a custom resolution. The display native timings at 240Hz are: Horizontal refresh 272kHz, Vertical 240Hz, pixel clock 617MHz.

Fix 3 – Set High Performance Power Plan

Open Power Options (powercfg.cpl) and select High Performance or the Lenovo custom performance plan. Battery Saver and Balanced plans cap display performance features. High Performance mode ensures the GPU and display controller operate at their maximum capability, making all refresh rate options available.

Fix 4 – Update Lenovo Vantage

Open the Microsoft Store, search for Lenovo Vantage, and ensure it is updated to the latest version. Older Vantage versions have a bug where GPU mode change does not fully propagate to the display controller firmware, causing 240Hz to remain unavailable even after switching modes. Updated Vantage versions handle the mode switch correctly.

Frequently Asked Questions

Why is 240Hz not available on Lenovo Legion 7i Gen 8?

The display is in Hybrid mode, routing through Intel iGPU which cannot drive 2560×1600 at 240Hz. Switch to Discrete GPU mode in Lenovo Vantage.

How do I get 240Hz on Lenovo Legion 7i Gen 8?

Open Lenovo Vantage, switch GPU mode to Discrete GPU, restart, then select 240Hz in Windows Display settings – Advanced display.

What is the maximum refresh rate on Lenovo Legion 7i Gen 8?

240Hz at 2560×1600 in Discrete GPU mode with NVIDIA driver 522.25 or later.

Does NVIDIA driver affect refresh rate on Legion 7i Gen 8?

Yes – driver versions before 522.25 may not show 240Hz options for the QHD display. Update from Lenovo Support or NVIDIA.com.

Conclusion

240Hz display option missing on Lenovo Legion 7i Gen 8 in Windows 11 is resolved by switching to Discrete GPU mode in Lenovo Vantage and updating the NVIDIA driver. Discrete GPU mode is required because the Intel iGPU used in Hybrid mode cannot drive 2560×1600 at 240Hz. Setting High Performance power plan ensures the display remains at maximum refresh rate during gaming.
