1.3.2.4 Sync Signal Levels
The monitor must accept sync signals from both 3.3 and
5 volt TTL logic families.The inputs shall sense a logic 0
when the input is 0.8 volt or less and shall sense a logic 1
when the input is 2.0 volts or greater. In addition to these
level requirements, there shall also be a minimum of 0.3
volt hysteresis provided for noise immunity (typically by
using a Schmitt Trigger input ).That is , the input level at
which the monitor actually detects a logic 0 shall be at
least 0.3 volt lower than the level at which it actually
detects a logic 1.If the monitor sync processing circuits
are designed around the 3.3 volt logic family ,then the
sync inputs must be 5 volt tolerant .
TTL input loading shall be equivalent to one TTL input
load. When logic 0 is asserted by a sync input , the
maximum current source from any single monitor sync
input to the driver is 1.6 mA .When logic 1 is asserted ,
the maximum current source from the driver to any
single monitor sync input is 400 uA .

1.3.4.2 Factory Assigned Display Modes
There are 17 factory pre-set frequency video
modes. These modes have a factory pre-set for all
characteristics affecting front-of-screen
performance. When the system is powered-
on,previously stored screen parameters for a pre-
defined mode will be recalled if the operating
mode is one of those stored in memory. If the
operating mode is not one of those stored in
memory, the monitor CPU will select the PRESET
timing for a mode that is the next lowest in
horizontal scanning frequency to the mode being
currently used. The screen parameters may be
adjusted by the use of the front bezel controls and
then may be saved as a user defined mode. The
monitor shall include all the preset video timings
shown in the following page.(Please see Note.(3) )

(3) Factory model :
After we first burn the code into the flash, every preset-model we run first must do auto-adjusting.
Then it'll not do auto-adjust again when we changed preset-mode back including AC on/off DC on/off.
The only way that preset-mode do auto-adjust again is press '' Internal Factory Reset''.
(4) User mode :
The code should memorize 9 timing mode exclusive of preset-modes as use mode and do auto-adjusting.
When user set a new mode that is not among previously. It'll do auto-adjusting then be solved to user modes.
The new mode will overwrite the first memorized user modes.
The user modes be cleared is same as Factory mode. Just do '' Internal Factory Reset''.

second and OFF for one second for seven consecutive after
operating for one hour at full load, 25oC, and nominal input line
voltage.

the EDID file for the first two minutes of operation
following power-up UNLESS some action taken by the
user or the host CPU forces the write (for instance,
requesting the serial number via the OSD).
Furthermore, it is recommended that CMOS switches
be incorporated to isolate the DDC IC from outside
connections while the EDID Fault Management is
being updated. This is to prevent corruption of the data
by attempts to read the data while it is being changed.
1.3.9 Firmware Update Function (same ISP function)
The update firmware need through from the D-Sub
