I The bright value is determined by the image quality setting table based on the user setting step and
the common inverted output amplitude adjusted value (COM AMPAJ).
This bright value controls the output of [DACDI] of the monitor micro computer terminal.
Supplement 1) When the bright value is changed in the test mode, however, it will not be reflected in the user
setting step value.
Supplement 2) In the test mode during monitor unit operation, the user setting step will not be reflected in
the bright value calculation.
Note 1... The "black density (=bright)" adjustment by the user is accomplished only by controlling
the common inverted output amplitude, and the brightness of the double window IC is not used.
Note 2... The content of bright and of RGB simultaneous contrast are reference values (adjustable though)
only when adjusting other items, and are not stored in the EEPROM.
Note 3... Be careful as the content of R(G/B) output DC offset, main Y contrast and sub Y contrast are different
between the displayed values (EEPROM written values) and the register setting values in
the double window IC.
(Because the relationship between the double window IC register value and the screen output
value is not linear, there is a need for conversion by software.)
The cases where the displayed value (EEPROM written values) and the register setting values in
the double window IC are different are summarized below.
