Do You Use HDR?

Well, most of the gaming monitors do not really support real HDR, just HDR400 (as in my case). I never managed to properly set up via Windows calibration tool, it was always slightly off, be it slightly washed out and/or to bright. Simply never got a setup that was 1:1 compared to non-HDR using Windows only. In contrast, MSFS always looked kinda ok, but somehow I still do not like the looks. 

Of course I am aware that filters are not the same, but the colour corrections I achieved using filters result in a better image imho. That is all.
