Issue: HP X32 monitor changes backlight brightness by itself automatically

[rlatte]

My HP X32 gaming monitor is otherwise awesome, but it has one issue that has me seriously considering returning it unless it can be solved somehow. The monitor seems to change the backlight brightness automatically based on the lightness/darkness of the displayed content. What this means in practice is if I for instance change from a white fullscreen window (i.e. Notepad) to a dark fullscreen window (i.e. Steam), the monitor ups the backlight brightness. The inverse is also true. Changing back to a white window lowers the backlight brightness, so there's this kind of weird brightness compensation feature going on. The change of brightness takes only about a second and it's really annoying especially in games/movies where the content luminosity changes often suddenly. Not to mention that it is a total dealbreaker considering any kind of visual creative work on the monitor where the image needs to be absolutely consistent all the time.

I have toggled every setting in the OSD menu of the screen without any results. I have also tried every imaginable option in Windows settings, and nothing helps (HDR on/off, color space settings etc.). None of my other monitors or my TV do the same connected to the same PC, and I also recently changed my GPU from AMD to NVIDIA and that also did not have an effect on the X32 monitor's brightness behaviour.

So I guess my question is, is there anything I can do to get rid of the automatic brightness behaviour or is it in fact baked in into the monitor?

hi

This behavior seems abnormal to me.
this is neither from windows nor from the graphics card, if you have tested another monitor with no problem
but I see absolutely nothing that could explain it here:

And I would find it rather curious as an option, if it changes so often
no for me, do not wait contact the dealer!
