The biggest issue is I CANNOT get the Bias and Gains to work properly. Using a 2pt approach of 30/80 or 30/100 or even 10/100 doesn't work as the controls overlap (changing Bias affects Gain almost 1:1 and vica versa).
The other issue is the 10pt controls do not match up to 10 step patterns if local dimming is on. However, if I turn local dimming off to calibrate the results don't hold up once I turn LD back on for real world viewing.
Any input on this particular TV and the best approach for calibrating?
Sometimes a firmware update can cause buggy issues that a factory reset of the device may alleviate.
Double check the recommended precal settings. 2pt doesn't have to be perfect as it is only intended to close the gap for multipoint to finish the job. Try to only use reductions with 2pt if possible. Increments may cause issues, especially if you run out of one or more color with gain.
Multipoint alignment accuracy may vary from unit to unit. If readings don't line up with adjustment values, get creative. I created a custom 100 point levels profile for Calman for this type of situation. Once the exact alignment targets are identified, create a new custom levels profile with the new points.
I recommend to leave local dimming on during calibration if you intend to have it on for viewing content. If you run into issues with low level readings while local dimming is on, then it might be beneficial to use APL patterns.
Make sure the correct meter profile for the display type is used. Try to calibrate in as dark of an environment as possible. Any ambient light may effect readings, including from calibration laptop/computer monitors.
Please post all of your data results so we can see if further recommendation is needed.
