Windows has a bug that affects HDR calibration for multi-monitor setups, causing incorrect peak brightness data to be applied across different displays. This results in distorted colors and highlights, particularly impacting gaming experiences where games draw settings from Windows. The issue is suspected to be triggered by the device entering standby mode, waking from sleep, or physically swapping display cables. Microsoft has not officially recognized or fixed this problem, leaving users to manually check their display profiles or restart their systems as a workaround.
