  • Notebook (generic)

    Cannot keep ALLM and VRR simultaneously active in a stable way with the newest consoles — a low-level compatibility fault. Its "1ms Motion Blur Reduction" strobing mode is mutually exclusive with FreeSync/G-Sync Compatible at the hardware level; enabling one irrevocably disables the other. The panel is also prone to atypical IPS dark-smearing during fast camera pans.

    FreeSync/VRR can't be enabled in AMD Adrenalin despite using a known-good dock and DisplayPort cable.
