3.8. Controller Requirements
3.8.1. General Requirements
The monitor shall include a controller capable of converting the analog RGB signal from a standard WSXGA
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, 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.
3.8.2. 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 1680 x 1050 is automatically expanded to fill the entire screen.
3.8.3. 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.
3.9. DC - AC Inverter Requirements:
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).
3.10. Power Supply Requirements
The AC to DC converter power supply for the monitor shall be an integrated power supply. This power supply shall
have an IEC receptacle for mains power input and provide sufficient power for the monitor, the backlight assembly
and the "Dell Sound bar", and shall meet all requirements specified in Table 2.
