AP440FX Motherboard Technical Product Specification

1.9.2 S3 ViRGE/DX Graphics Subsystem

The optional onboard graphics subsystem uses the S3 ViRGE/DX graphics controller, with the
following features:
•
64-bit graphics engine with accelerator core
•
24-bit RAMDAC/clock synthesizer
•
Dual programmable clock generators
•
DCI-based linear addressing scheme
•
S3 Streams Processor, which enables the conversion of video data from YUV format to RGB
format and accelerates display scaling while maintaining picture quality and frame rate
•
3-D graphics support including flat shading, Gouraud shading, and advanced texture mapping
•
S3 Scenic Highway support for hardware MPEG

The S3 ViRGE/DX graphics controller supports more modes than shown above. The graphics drivers provide options for
additional resolutions.

1.9.3 LBP VESA Feature Connector

The AP440FX motherboard supports a 34-pin VESA feature connector (which also accepts a
26-pin peripheral plug) for synchronizing graphics output with an external NTSC or PAL signal
and a shared frame buffer interface to maximize multimedia performance, as well as the LPB or
Scenic Highway that provides a glueless bi-directional interface to a video companion device such
as an MPEG/live video decoder. The AP440FX also supports other VESA standards such as the
VESA DPMS protocol to put a DPMS compliant monitor into power saving modes and the VESA
Display Data Channel (DDC2B) that permits transfer of monitor identification and resolution
support data for ease of use.
