7 months ago I did reset my Kuro 8G: after 840 hours of use yesterday I used the probe to assess its condition.
I remember that on that occasion, after the reset, I performed no voltage change because I got a disappearance of Red Tint, a striking reduction of Nero (from 0.015 - 0.017 cd/m2 to 0.005 cd/m2!) and no artifact as Magenta Sparkles, Black Rain or Black Lag.

Precisely for this reason it was right to expect a return to previous conditions ... and so it was
Not so much for the Red Tint (which was not evident even before) as for Black level returned to previous levels.
This is screenshot related to the reading of Near Black + GrayScale Pre-Reset
performed yesterday, before the "cure."
You can see the Black at 0.0159 cd/m2:
Given the good results of the previous Reset I decided to do it again, but in this case I decided to change, after Reset, the voltages to try to avoid returning to the starting point in the space of a few months.
This is the Near Black Post-Reset
(5 minutes after the previous reading) without any change of voltages.
Black has become, after only Reset, 0.0077 cd/m2 (almost half!)
Finally, this is the result after some change in voltages - Near Black Post-Reset + Changed Voltages
Amazing Black: 0.0019 - 0.0020 cd/m2 (almost similar to the KRP!) + very linear Gamma.
Near Black too dark, but I think it will improve spontaneously with driven bedding by internal algorithms:
Final big question: will this condition remain stable over time? We will see in the next episodes ...
