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

1.3.2.1 Video Signal Amplitudes
The three video inputs consist of Red ,Green , and Blue
signals, each with its own coaxial cable terminated at the
monitor. These video signals are analog levels, where 0
V corresponds to black , and 700 mV is the maximum
signal amplitude for the respective color, when each
signal is terminated by a nominal 75.0 ohms .For a given
monitor luminance levels are measured using this
defined video amplitud driving a monitor meeting the
termination requirements .The signal amplitude is not to
be readjusted to compensate for variations in termination
impedance.
1.3.2.2 Video Signal Termination Impedance
This analog video signal termination shall be 75
which shall be resistive with a negligible reactive
component
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 .
