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 impendence.

1.3.2.2 Video Signal Termination Impedance

This analog video signal termination shall be 75

1% 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 .

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

1.3.4 Monitor Modes and Timing Capability

1.3.4.1 Format and Timing

The monitor shall synchronize with any vertical

frequency from 55 to 81K Hz , and with any

horizontal frequency from 30 to 94KHz. 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 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) )

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) )
