I agree it's confusing. Seems so simple but setting it right makes a big difference in PQ. On my TV I have set the +2% bar to be just barely visible. In fact if you click down one more it will disappear. I have a plasma Panasonic...

I decided to take some objective colorimeter measurements with HCFR software and an i1 Display LT meter regarding various color setting methods. The key data to observe on the chart (below) is the significant increase in Luminance error...

I wanted to refocus the objective of the thread and summarize the data and contributions to date. First, the original thrust was to somehow find an optimization method that objectively (uses colorimeter measurements) and subjectively...
