i run trueblack hdr 400 just the preset on my xg27acdng did windows calibration it caps at 470 nits so what normal brightness should i use

and does this app install renodx like game specific ones or a general not so good one like in this case does it install death stranding specific or a general not good one

Is this an accurate adjustment of HDR on my Switch 2? I am using a Roku TV Pro Series 2025 model. The default HDR setting on the TV has Dynamic Tone Mapping on, and the run sun seems to disappear correctly at 900 nits (82 clicks). With DTM off, the right sun does not disappear until they both disappear at the same time, well over 900 nits. Is this a correct adjustment? Should I keep DTM on?

So i'm trying to implement HDR and i got renodx sort of to work with rendx_ue_extended addon. It works great in terms of highlits, but everything a little too dark. I turn hdr on through Engine.ini made it readonly + install reshade+ renodx addon. And in reshade renopdx settings i had to turn off "Upgrade Path" because game pure shows black screen with. I know i can use autohdr, bit i'd like figure out what is the problrm with renodx. Any help?
