3)Copy CMS0 to CMS1
4)When watch HDR source , enable CMS1 HDR Mapping, set Gamma to 3D LUT =SDR
Before replying to your questions please input a 1080p source to the Pro, bluray disc or cable box.
1) In Output Setup under column heading "601/709" you will see CMS0. Change this to CMS1. Then go to Output CMS's CMS1 and select or confirm Colorspace=SDR2020.
2) In Chromapure Initial Setup select colorspace=YCbCr422-709 and Color Intensity to 100%. In Options set Gamut to Rec 709 and Gamma to 2.4.
In Auto-Calibration Setup set Gamma Target=2.4. Set Grayscale Mode=12 point and SDR2020. Uncheck Reset. Check Grayscale Calibration and Matrix Calibration 729 points. Check Filter Colors Outside Display Gamut. Click Next.
Now click Measure. After RGB pattern sequence set Intensity Filter intensity to 100% and click Filter followed by Apply. Proceed with Auto-Cal.
3) Don't copy anything. Go back to step 1 and where you previously changed CMS0 to CMS1 under the 601/709 column, change it back to CMS0.
4) Check your UHD player and be sure it is set to output HDR2020. No HDR to SDR conversion or Strip MetaData.
Play a UHD 4K bluray. The Pro will recognize it as HDR2020 and use CMS1 in the HDR2020 column you just calibrated while it was temporarily set in the 601/709 column.
Because you set CMS1 Colorspace to SDR2020 that is what the Pro will send to the projector. If you have a JVC projector it will not go to Gamma D because you sent it a SDR signal, not HDR.
Because the Pro recognized you supplied it with a 4K image it will automatically enable Intensity Mapping. There are two places where you can check and adjust Intensity Mapping---Output>CMS's>CMS1>HDR Mapping and Input>Options>HDR Setup.
