It has per-app HDR profiles, auto-HDR, content-only HDR (e.g. you want to watch an HDR video but don’t want your desktop to be HDR), and, on a related topic, better handling of VRR and windowed full screen.

Not that Windows 10 is wildly deficient in these areas, but it has a lot of improvements with display settings and capabilities in general. In my experience with the Windows 11 display settings, it’s an overall big improvement, and I do kind of miss it now that I’m on Linux (e.g., setting up virtual displays with Apollo streaming so that client game stream devices have their own separate display settings per-device was a breeze thanks to the excellent way Windows handles and configures unique sets of attached displays.)

Interesting.

Unlike high refresh rates, 1440p resolution, and variable refresh rates that all were so clearly steps above my previous, 60hz basic HD display that I regretted not being an early adopter, HDR has been an immense letdown.

I can't even tell if it's on or not, even while my monitor and GPU assure me it is. As far as I can tell, the most obvious feature was shabbier looking colors, because they are de-saturated for some reason.

I played with the settings tab shared here[0], but the stupid "Brightness" slider is not obvious at all. Is bright good? Is bright bad? WTF?

That post has some other things to look into though, maybe I need a calibrated color profile? Will that get me colors that actually look better than an SDR display? Who knows.... It doesn't make any sense to me that improved brightness space should somehow result in less saturated colors...
