RGB levels is more of representation of deviation from your white point reference (i.e. D65), and not what I'm referring to.
I'm talking about the "Gamma graph" (Graphs->Gamma Graph or toolbar button
) which can also be seen in the Information "Gamma" drop-down from the main ColorHCFR window. By default it only shows a Yellow luminance line. You need to right click on the Gamma Graph display and enabled the individual Red, Green, and Blue gamma plots. It will be populated when you take grayscale measurements
First balance the Red, Green, Blue plots on the Gamma graph so they lined up as much as possible on both the low-end and high-end.
Second do a rough correction of RGB Levels to balance the Red, Green, Blue plots on both the low-end and high-end.
At that point, it's a balancing act between the "Gamma graph" and the "RGB Levels". Switch back and forth between the two as you fine-tune with 5% grayscale measurements.
Overall "RGB Levels" (white balance) takes priority, but using the Expert Color controls from the OSD, you should be able to achieve close to matching Red/Green/Blue Gamma plots as well.
I've found this to be important with these CRTs, since otherwise you could be fooled by perfect color temperature & luminance gamma plots, when your Red & Blue gamma plots are way off target.
