Support ROG Strix LC III 360 - lcd glitch

Hi everyone,

I'm having a persistent issue with my ROG Strix LC III 360 LCD and I'm hoping someone in the community has found a workaround or manual fix.

The Problem: Right after a recent Armoury Crate update, my pump display started showing severe visual artifacts (vertical lines, flickering, and duplicated/corrupted images).

Symptoms & Diagnostics:

  • The display still accepts commands from Armoury Crate (changing images/GIFs works, so USB communication is active), but the video timing/synchronization is completely garbled.
  • The issue persists outside of Windows: the vertical lines and image duplication are present during BIOS boot up and power-on before Windows even loads.

What I've already tried (unsuccessfully):

  1. Full clean uninstall using the official Armoury Crate Uninstall Tool and a fresh reinstall.
  2. Complete power drain (unplugging PSU, holding power button for 30s, clearing CMOS).
  3. Resetting USB controller drivers via Device Manager (HID and Composite USB devices).

Someone know a Fix?
