Note1 : The contents of [COM DC, clock phase] should be reflected to the reverse output center reference value.
6. Screen specification of each mode
Actual OSD screen samples are showed inside of the thick frame in the chart below.
The numbers in the chart are the changed parts during adjustment in each screen (maximum value is showed in the sample).
The items are for design review and line adjustment.

Line adjustment 1 mode
• Adjust common reverse output amplitude by line in order to cancel the variation of hardware quality.
• [COM AMPAJ] is a default value set by line and stored in EEPROM.
• In the normal operation, [BRIGHT] is determined based on COM AMPAJ (common reverse output amplitude adjustment)
and the attached “Image quality table” according to user setting steps, and this value controls monitor microcomputer
[COM_AC] output.
• User’s adjustment of “Black density (=bright)” on this product is done by controlling common reverse output amplitude only,
not done by brightness of 2-display IC.
• User’s adjustment of “Black density” is not reflected to [BRIGHT] in the test mode of single monitor.
When adjusting [COM AMPAJ], [BRIGHT] changes accordingly. (Memorized [COM AMPAJ] is the same as the [BRIGHT]
value of step0.)
• When entering test mode in product condition, “Black density” by user’s adjustment is reflected to [BRIGHT] value.
If changing [BRIGHT] value in the test mode, it is not reflected to the user setting value.

■
Note1 : The contents of [BRIGHT] and [CONTRAST] are the reference value for adjusting the other items,
and not stored in EEPROM.
*
■
Note2 : Be careful about the contents of [R, G, B OUT BIAS] and [RGB, CMP CONTRST] since their indicated value /
EEPROM written value and their registered value of 2-display IC (TC90A96AFG) are different.
(Software conversion is running because correlation between registered value of 2-display IC and display output is not linear.)
