Adaptive brightness still on in my new PC, despite turning it off both on my monitor and in Windows

Problem as title, really annoying as whenever I’m playing a video game and it goes into a dark area, I can’t see HUD information. And whenever there is text on a black screen, I can’t read any of it.

Have you checked the power settings in Windows? Sometimes adaptive brightness can be controlled there as well.

Yeah, I had a similar issue. Try looking for any settings related to HDR or brightness in your graphics card control panel too.

Make sure your monitor’s firmware is up to date. Sometimes these issues can be fixed with updates.

Thanks for the tips! I’ll check those settings and see if updating the monitor helps.
