Chapter 4. VGA, LCD Feature
4-1. VGA Feature
ENDAT-4066i provides an integrated graphics (Intel® Extreme Graphics 2)
accelerator delivering cost competitive 3D, 2D, and video capabilities. It contains an
extensive set of instructions for 3D operations, BLT (Block Level Transfers) and
Stretch BLT operations, motion compensation, overlay, and display control.
ENDAT-4066i video engines support video conferencing and other video
applications. Instead of a dedicated local graphics memory interface,
ENDAT-4066i applies UMA configuration for optimal memory utilization and
performance that deliver 3D graphics with sharp images, fast rendering, smooth
motion and extreme detail.
High bandwidth access to data is provided through the system memory port.
ENDAT-4066i can access local graphics data located in system memory at 2.1
GB/s (DDR266) 2.7 GB/s (DDR333), or 3.2 GB/s (DDR400) in single-channel
mode.
ENDAT-4066i applies Intel® DVMT for optimum the system utilization via system
chipset. DVMT is a concept be applied in the Intel® 865GV chipset wherein the
optimum amount of memory is dynamically allocated and de-allocated as needed
for balanced graphics and system performance, through Intel® Direct AGP and a
highly efficient memory utilization scheme.
The on-board Graphics Controller supports a full AGP implementation internally to
remain compatible with existing software and programming models. However,
since the engine is integrated, it enjoys a higher bandwidth and lower latency than
is possible with discrete solutions.
The controller of ENDAT-4066i supports 2 types of display: CRT and LVDS panel .

4-2. LVDS Panel And TV Feature (optional)
These 2 devices are alternate feature; can not exist on the same system at the same time.
LVDS Panel Interface
The on-board graphic controller supports industry standard LCD panel, LVDS
interface only, with 1 channel (18 or 24) and 2 channels (36 or 48bit) data width.
LVDS interface provides low voltage, high speed and low EMI serial DC-balanced
differential data via optional onboard LVDS.
The flat panel interface provides or supports following functions for various panels:
- Generates LVDS flat panel channels like clock and data channel.
- Generates different video data formats to directly drive different types of
panels (18, 24, 36 or 48bit)
- Wide screen resolution as 16:9 or 16:10.
- Vertical and horizontal expansion of video displays to LCD panel resolution
- Vertical and horizontal centering
- Panel power sequence
Please note that the default setting is with “CRT only”. If the LCDdisplay features is
required, the setting will need to be revised in the system BIOS setting: “Display Device”
under “Advanced Chipset Features
” unless clients specified the display type while order.
