My question: Can I somehow do the same in HCFR?
Not through madVR no, you can display a white patch and measure it using the internal generator (view->test colors) but that can't be piped through madVR. You could do one of two things, use argyllCMS "dispwin" with the -dmadVR swtich or use MPC to display a white pattern from an mp4 or DVD test disk.
Thank you, zoyd!
So in HCFR I would measure the whole Greyscale or Gamma,
then make my adjustments for each IRE point or Gamut point in the projectors menu
and then take another reading of the whole Greyscale (or Gamut) and see how it is now.
Is that what you guys do?
Is it even better than correcting point after point taking continous readings (as I did before with Calman)?
Many thanks for the great job you are doing!
