     - X-Rite Pro but demonstration uses DISPLAYCAL!!! (FOSS software) !!!
        - At ~11:00 he describes turning any of the display processing off (to dummy mode) so that the graphics cards does all the work!
        - The value of watching what he turns off to get to a "dummy" display mode could be extrapulated to the Projector profile settings!!
        - At 17:20 the DisplayCal part starts

    - Info of importance:
      How do I set-up automatic test patterns?
      - A Chromecast can be used as a pattern generator with no special set up
      - "it is recommended that you use madTPG if you want to calibrate in PC levels because it will dither the output levels and reduce or eliminate any rounding errors." madTPG is madVR's pattern generator. Yjios is all about getting RBG (0-255) rather than 16-235 (8-bit) HCFR's generator. I don't really want to add that software if possible.

##HCFR HDR calibration
- See this post for HCFR HDR and some SDR calibration advise that I can actually use:
  https://www.avsforum.com/forum/139-display-calibration/1393853-hcfr-open-source-projector-display-calibration-software-401.html#post58617452
  - "for HDR10, use ST.2084 REC.2020 50%/50%"
      https://www.avsforum.com/forum/139-display-calibration/1393853-hcfr-open-source-projector-display-calibration-software-399.html#post58585446
  - HDR: "select @ HCFR ColorChecker Module the 'BT2020HDR_50_50' selection and @ Preferences the REC.2020 colorspace with ST.2084, and
          when you will take ColorChecker measurements, you will see the dE and the suggestions what you change to reduce dE."
    HDR: "Saturation level (50%) and lower Stimulus Level (50%) patterns"
      - APL (video) level: "APL they are talking about average input video level (stimulus) and not average relative luminance"
    HDR: "50% Stimulus has luminance target for 92.24 nits"
    - SDR: "REC709, Power Law 2.4, 100 nits: https://www.avsforum.com/forum/139-d...l#post58376904"
    - SDR: "Before starting the calibration, disable enhancements: https://www.avsforum.com/forum/139-d...l#post58376900"
    - SDR: "use power law 2.4 for night (100 nits) and 2.2 for day. (200-320 nits)"
- !!!! Once again I still don't know how to use HCFR to get a brighter picture out of the HDR image !!!!
- "Ignore the gamma curve when calibrating HDR. Use the Luminance graph instead. "
- !!!!"Set Reference to ST 2084.Calibrating projectors for HDR is tricky. You will get clipping at the top end as that represents
  10,000 nits! However, contents are mastered to "only" 1000 or 4000 nits, which still requires rolling off. You should avoid clipping below ~70% as that will be quite visible."
- "I also understand that I should use 50%/50% patterns when measuring colors against the bt.2020 color space. How do I set 50%/50% patterns in HCFR?"
  - Change the intensity setting for madtgp to 50%
- BT2020 color targets
