Just got it today and setup the HDR and it looks great, bright and colorful, but there is a strange issue about this brightness.

HDR on in windows 11 and in monitor, connected to RTX 3060 Ti Dp 1.4 on HP Omen 25L and when i open any window with white background the monitor stay bright for about 7-10 seconds and then dims itself by 30-40% and when i minimize the window and reopen it, the same thing happens, screen stays bright for few seconds and dims itself.

I've read the manual but no reasonable solution there about this issue.
Same thing happens on 160 or 144Hz, my Nvidia drivers are the newest ones and so is windows.

    I do not have a laptop, i have a desktop. This option for auto brightness applies to laptops or battery powered Win11 units, not desktops.

    I turned HDR off in Windows and monitor and the brightness stays the same so i assume something is wrong with the HDR program either in windows or Acer. I understand that if the display is not receiving HDR signal then it will not display HDR content but what does that have to do with static brightness?
    The display should stay at it static brightness until pixel change occurs.

    I will try older version of windows and display drivers but if that don't help, then i have no use for this HDR monitor that is dimming itself by trying to save power on my desktop? Something is wrong..
