A brief video interruption may occur when switching between windows or if a particular window requires more desktop space. This behavior is seen when Dolby Vision HDR (10-bit depth) is enabled on the monitor. When the display is set to Dolby Vision mode, Windows attempts to use the Dolby Vision HDR features for the active application or window, especially if it occupies additional desktop space. If an application that does not support Dolby Vision HDR (like the Command Line) becomes active, Windows switches to standard HDR. This change necessitates a screen refresh, causing the display to briefly power off and on. Affected Monitors: AW3225QF AW2725Q AW2725QF S3225QC
