1.3.5 Controller Requirements
1.3.5.1 General Requirements
The monitor shall include a controller capable of
converting the analog RGB signal from a standard
SXGA resolution video controller in the CPU to a
signal which can be displayed on the panel. The
controller will include a PLL, A/D converters, LVDS
transmitter and other circuitry necessary to perform
its function. The PLL shall be stable enough to
ensure that a static image from the CPU is placed
in the same physical location on the flat panel in
each frame.
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) )

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
---socket for DC power out. The brick shall provide
sufficient power for both the monitor and the backlight
assembly, and shall meet requirements specified in Table
2.
