Hello all. Hopefully one of the calibration experts can answer a simple question I have regarding Avia and color settings.
If a set's saturation and tint/hue controls have been calibrated using the blue filter and the set also has excellent color decoder results (all primaries are at 0 percent using the Avia II color decoder pattern) then what does it mean when one goes into the red and green bars test pattern and the tint/hue are a bit off? i.e. saturation is perfect as the color decoder pattern indicates yet in order to get the tint set for green, I have to tick up the controls about 5 notches. Red is actually the same as blue. Is this indicative that the set's primary and secondary color points are off the standard? I would assume that by having to tick up the tint control on the green bars pattern (which moves it toward Red and away from Green on the actual tint setting) that it means in order to get the same amount of green in cyan and yellow I need to remove some green from cyan and remove green/add red from/to yellow.
Related to this question, what does it mean if the flashing boxes never disappear? For example, when using the blue bar pattern, the flashing completely disappears for both saturation/tint yet even though red's optimal tint setting is the same when viewing the red bars pattern, the flashing does not disappear.
Finally, if all of the above is indicative of the color points being off the SMTPE specs, how common is it for this to be fixed with IS&F calibration? Do modern sets allow for color management such as this?
thanks for any clues one can give me on this subject.
