changing calibration repeat threshold and patch count

[Mark Appleton]

Is it possible to change the repeat thresholds and patch counts for the calibration step (not the profiling step)?

I know that changing the “profile quality” reduces the repeat threshold indirectly (high quality gives me 0.4 DE for 90 patches), but is there a way to set it explicitly?

Hi,

thats what Vincent says  in the “Graphics card LUT vs. display LUT” post:

“There are two set of measurements:
-calibration patches (for grey), controled by calibration speed setting
-profilling patches (user controlled, the ones you named), not related to calibration (for making a LUT3D for madVR or Resolve maybe, but not for desktop calibration)”

So  if you want to increase the patch counts, you have to decrease the calibration speed.

I haven’t tried it yet.

It looks like I’ll have to go into the source code, then, if the slider is the only way to control the greyscale calibration quality.
