hi Nathan. I think the new Samsung’s are all BT1886 as a preset and then 20 point?
When doing a 10 point adjustment, select 20 points in ChromaPure or Calman and you will be able to better see how the points between the different levels of adjustment are being affected.
the one i was working on only listed 2 point greyscale and 10 point grayscale.
i managed to calibrate it fairly well on 2 scale but i could literally turn any of the colours to full at 70% for example and not see a single change on the meter.
