there could be a lot of reason for that one for example you told your projector the input colorspace is bt2020 in this case madVR should be set to bt 2020 too.
than we have a line saying HDR type SDR and HDR meta data...
what ever is going on here this is not what SDR should provide.

i can't tell you anything about gamma here gamma 2.4 without calibration is just something unknown same for normal could be gamma 2.14 with a "nice" S curve.
The movie being displayed is 4K HDR.. I am using RGB FULL 4.4.4 on my GPU end at 12bit colour.. The projector can do BT2020 for HDR and REC709 for SDR..

What I am doing is converting HDR to SDR with madVR in order to get a better tone mapping as the HDR mode in JVC projectors are dark and not very pleasing..

As mentioned before with the colours space set to BT2020 in madVR, the image looks like SDR but when it's not selected (disable calibration controls for this display) then with HDR movies the colours pop and seem very nice apart from skin tones being slightly red than usual..

What I am asking is for those who use madVR to convert HDR to SDR, do you select the display calibration option for this display or select this display is not calibrated? Thanks.. Hope this makes sense... Name:  MVIMG_20180611_003440985.jpeg
