Simultaneous Scan Mode; Video Mode Support - Compaq Armada e500 Series Reference Manual

Simultaneous Scan Mode

The RAGE Mobility-P provides simultaneous display operation with Multisync variable
frequency CRT, PS/2 fixed frequency CRT, or TV monitors and SS or DS LCDs.
Resolutions, refresh rates and display data can be independent. Scanning is supported in
high-resolution modes. A 640 × 480 LCD panel can be used in simultaneous mode with
a CRT at 1024 × 768 (or 800 × 600) using scanning. The LCD panel displays only a 640
× 480 portion of the 1024 × 768 (or 800 × 600) display. This portion may be scrolled to
different areas of the higher resolution display with either a keyboard or pointing
device. This allows the user to disconnect the CRT and still be able to read the flat panel
when in high-resolution modes.
The system has the capability of driving both the LCD display and the external CRT
display simultaneously as well as switching between them. The LCD/CRT switching is
handled by the RAGE Mobility-P and is controlled via Fn-F4 key.
