Acer RA19WAANU Computer Monitor User Manual


 
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

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) )
