which shall be resistive with a negligible reactive

1.3.2.3 Synchronization ( Sync ) Signals
The Horizontal Sync (HS) TTL signal is used to initiate
the display of a horizontal line. HS may be either active
high or active low, depending upon the timing .The
Vertical Sync (VS) TTL signal is used to initiate the
display of a new frame .VS may be either active high or
active low, depending on the timing
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 .

The monitor shall synchronize with any vertical

frequency is out of the above – specified range,
the monitor shall display a warning screen
indicating that the input frequency is out of range.
Under no circumstances shall any combination of
input signals cause any damage to the monitor .
1.3.4.2 Factory Assigned Display Modes
There are 21 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
opera
ting mode is not
one of
those stor
ed 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
moni

1.3.4.3 Mode Recognition Pull-in
The monitor shall recognize preset modes within a
range of +/-1KHz whichever is less for horizontal ;
and within +/-1Hz for vertical.
1.3.4.4 User Display Modes
In addition to the factory pre-set video modes,
provisions shall be made to store up to 9 user
modes. If the current mode is a user mode, the
monitor shall select its previously stored settings.
If the user alters a setting, the new setting will be
stored in the same user mode. The user modes
are not affected by the pre-set command. If the
input signal requires a new user mode, storage of
the new format is automatically performed during
user adjustment of the display (if required).(
Please see Note.(4) )

1.3.5.2 Video Stretching
The monitor shall contain provisions to “stretch” the
video signal, so that an input signal from the
computer in any resolution smaller than 1366 x
768 is automatically expanded to fill the entire
screen.
1.3.5.3 Panel Timing and Interface
The controller supplied with the monitor shall
control all panel timing. This controller shall
adequately insulate the monitor from the computer,
so that no possible combination of input signals
from the computer shall cause damage to the flat
panel or any other component of the monitor. The
LCD panel interface shall support the TFT
standard.
1.3.6 DC - AC Inverter Requirements
The DC-AC inverter is on the power board. The
frequencies used by the DC-AC inverter used to power the
backlight shall be chosen so as to prevent any noticeable
effects on the flat panel (such as a rolling effect).
1.3.7 Power Supply Requirements
The AC to DC converter power supply for the monitor shall
be an external AC to DC converter ”brick” This brick shall
have an IEC receptacle for main power input and a pin - in

1.3.5 Controller Requirements
1.3.5.1 General Requirements
The monitor shall include a controller capable of
converting the analog RGB signal from a standard
SXGA resolution video controller in the CPU to a
signal which can be displayed on the panel. The
controller will include a PLL, A/D converters, LVDS
transmitter and other circuitry necessary to perform
its functio
n. The
PLL shall be
stabl
e enough to
ensure that a static image from the CPU is placed
in the
same phys
ical locati
on on
the flat panel in
each frame.
1.3.4.3 Mode Recognition Pull-in

1.3.8 Display Communications Channel
The monitor assembly shall provide a display
communications channel that conforms to VESA
DDC2Bi hardware requirements. This configuration
shall contain the 128-byte EDID file as specified by
VESA EDID standard.The monitor should not write to
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 attempt
s to
read the data
while it is
being chang
ed.
1.3.9 Firmware Update Function (same ISP function)
