hi to all,
Just wanted to ask those technical people here if they can share their knowledge concerning service menu commands,
like Rcut, Bcut,Gcut and their respective drvs. From the research I made I think this will be needed if the optimum color settings can not be achieved anymore in
the user menu settings when calibrating the unit. Hope someone can share their experiences.
Just wanted to add something to this taken from the web;
Here are some of the 'useful' settings :
RCUT, GCUT and BCUT are known as the colour cut-offs
RDRV, GDRV and BDRV are known as the colour drives
Many of the remaining settings are not relevant to our calibration needs, and are likely to cause more harm than good should
you change them so be careful when tweaking.
Each service menu setting is displayed in three columns: in the first column there is the setting name, the second column contains
the setting value in hexadecimal notation, and the third column contains the same value in binary notation. The binary column can
be ignored, it is not relevant to the controls that interest us.
The drives manage the luminance levels and as we've discussed these need to be balanced using the 'continuous measures mode'.
Each time you increase the value luminance increases, similarly decreasing the value results in a decrease in luminance. In my case,
I wanted to decrease blue over-saturation, so I decremented the BDRV until it was brought into balance with the other two colours.
Typically, when balancing you leave GDRV untouched so that it acts as a reference level.
The cut-off controls are used to balance the dark end of the grey-scale, while the drive controls balance the bright end of the grey-scale.
You use them by balancing colours using the method I described earlier, only at a very low IRE level (< 20% grey / 20 IRE); however I'm
not confident in Spyder 2's ability to report accurately at low light levels so I did not modify them.
As before, you adjust the red and blue cut-off controls to balance, leaving the green cut-off control as a reference.
p.s. I'm trying to post my researches here so when the time comes somebody tries this methods we can share our experiences and
results.
Thanks
