Measure of Cutoff Gain, the data comes when adjusting the screen voltage. It is set to the point
where changing red into green. RGB Output. By sending the standard pulse data, it receives
feedback from RGB drive. It is low light data.
Measure of Green of Drive Gain, the data that indicates the value of High Light. It has the same
principle as MRC R G B
Internal brightness measurement. For AKB, an 1-chip sends RGB standard pulse and sets
the level of the standard pulse.
White drive measure control. IBRM is the standard pulse of low light. WDRV is the standard
pulse of high light.
Cathode drive level. Sets the standard luminance of high light different by CRT and inch.
This uses the same register as the RED//GREEN/BLUE drive in video adjust-1.
Cutoff level R. Uses the same register as the RED cutoff in Video adjust-1.
Cutoff level G. Uses the same register as the GREEN cutoff in Video adjust-1.
Cutoff level B. Uses the same register as the BLUE cutoff in Video adjus
