1.3.4 Monitor Modes and Timing Capability
1.3.4.1 Format and Timing
The monitor shall synchronize with any vertical
frequency from 50 to 75 Hz , and with any
horizontal frequency from 31 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 13 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) )
