1.3.2.5 Sync Signal Loading
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 .
1.3.2.6 Abnormal Signal Immunity
The monitor shall not be damaged by improper
sync timing , pulse duration , or absence of sync ,
or abnormal input signal amplitude ( video and/ or
sync too large or too small) , or any other
anomalous behavior of a graphics card video
generator when changing modes , or when any
combination of input signals is removed or replaced
. Additionally , under these conditions , the monitor
shall not cause damage to the driving source
1.3.3 User Controls and Indicators
1.3.3.1 Power On / Off Switch
The monitor shall have a power control switch
visible and accessible on the front of the monitor .
The switch shall be marked with icons per IEC 417
, # 5007 and # 5009.The switch shall interrupt the
DC supply to the monitor
1.3.3.2 Power Indicator LED
The monitor shall make use of an LED type
indicator located on the front of the monitor .
The LED color shall indicate the power states as
given in Table 1.
1.3.4 Monitor Modes and Timing Capability
1.3.4.1 Format and Timing
The monitor shall synchronize with any vertical
frequency from 56 to 75 Hz , and with any
horizontal frequency from 31 to 83KHz. If the input
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
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) )

1.3.3.3 On-Screen Display
The Lite-ON On Screen Display system shall be
used , controlled by a Menu button. If the buttons
remain untouched for OSD turn off time while
displaying a menu , the firmware shall save the
current adjustments and exit. Also, if the video
controller changes video mode while the OSD is
active, the current settings shall be saved
immediately, the OSD turn off, and new video mode
is displayed.

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 /-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
