Just checked and the max parameter for 'Number of grayscale levels' is 100.
That allows a full 1% sweep to be run (most video levels stepping by 2, some by 3) but it is not possible to make a sweep of each and every greyscale level (by setting Number of grayscale levels to 255 or 219).
Increasing 'Number of near black levels' above 4 just increases the number of 1% steps anove 0, but does not allow video levels 17, 18, 19, 20, 21 etc... to be tested.
I'm not really interested in 255 or 216 greyscale sweeps but would like to find some way to easily measure greyscal near black at single-step levels (video levels 16 - 27).
Is there any way to do this with HCFR (view image)? If not, it this a simple request for the next release?
These LG OLEDs are very funky in the near-black range and I believe near-black characterization at a finer level than 1% is a capability that more and more Forum members would appreciate...
