[Support] Legion Pro 5i (16IRX8) - Horizontal flicker at 60Hz, but clean at 165Hz. Hardware or Driver?

[Support] Legion Pro 5i (16IRX8) - Horizontal flicker at 60Hz, but clean at 165Hz. Hardware or Driver?

Hey everyone, I’m experiencing a weird display issue on my Lenovo Legion Pro 5i and wanted to get some insight before I commit to a repair or a full panel replacement.

The Issue:

  • The Symptom: There’s a faint horizontal flicker/line across the screen.
  • Refresh Rate Variable: The issue is very visible at 60Hz, but it completely disappears when I switch to 165Hz.
  • Stable Image: The line is present even on static screens and isn't tied to GPU load (happens on desktop).
  • The "Screenshot Test": Screenshots and screen recordings look perfectly clean when viewed on another device.
  • External Display: Connecting via HDMI to an external monitor works perfectly—no lines or flicker there.
  • Physical Check: Moving the hinge doesn't affect the line at all, making me doubt it's a loose eDP cable.

What I’ve Already Tried:

  • Drivers: Performed a clean install of both Intel and NVIDIA drivers using DDU.
  • Settings: Disabled Variable Refresh Rate (G-Sync), Panel Self Refresh, and Display Power Savings in the Intel Graphics Command Center.
  • BIOS/Safe Mode: Interestingly, the lines are not visible in the BIOS or Safe Mode (which usually defaults to 60Hz).

The Dilemma: My warranty just expired. Since 165Hz works, I’m using that as a workaround for now, but I'm worried the panel is physically failing (T-Con or gate driver issue).

Has anyone seen a Legion panel fail specifically at lower refresh rates while staying stable at high ones? Is this a sign of an impending total display failure, or could it still be a deep-seated firmware/BIOS timing issue?

Thanks for any help!
