1 # (HDR content mapping is possible with any display, new or old.)
Display, new or old, this is' meant HDR panels with 10-bit or must be intended for panels LCD / LED 8-bit ?

doesn't matter. it even works on a 6 bit tn panel. don't think about it. it even works on an CRT.

2 # (Choosing disable calibration controls for this display will use the display peak luminance value to map HDR content to match the color gamut of the source.)

Explained so, what do you mean ? to ensure that parameter is' running madVR, (disable calibration controls for this display) must be switched off ?

just leave your current calibration setting as they are. in the past madVR didn't gamut mapping without a calibration setting this was fixed in version 0.89.19.

my panel Full LED measurement cd / m2 - 112 nits, like setting in this case I should set a value of 120 peak luminance?

you choice what looks best to you there is no standard for transferring HDR to SDR yet.
