HP Compaq d330 DT User Manual

Technical Reference Guide
The graphics controller (Figure 6-2) integrated into the 82865G GMCH component includes 2D
and 3D accelerator engines working with a deeply-pipelined pre-processor. Hardware cursor and
overlay generators are also included as well as a legacy VGA processor core. The IGC supports
three display devices:
♦ One progressive-scan analog monitor
♦ Two digital video displays (DVOB and DVOC) with the installation of an optional AGP
Digital Display (ADD) card in the AGP slot.
The two digital video output ports (DVOB and DVOC) are multiplexed onto the AGP bus and
accessed by an optional ADD card installed in the AGP slot (if present).
NOTE: The integrated graphics controller can support LVDS, TMDS, or TV output
with the proper encoder option.

Integrated Graphics Controller
Figure 6-2. 82865G GMCH Integrated Graphics Controller
Special features of the integrated graphics controller include:
♦ 200-MHz core engine
♦ 350-MHz 24-bit RAMDAC
♦ 2D engine supporting GDI+, alpha stretch blithering, and color space conversion
♦ 3D engine supporting Z-bias and up to 1600 x 1200 w/32-bit color @ 85 hz refresh
♦ Video DVD support:
The Intel graphics controller uses a portion of system memory for instructions, textures, and frame
(display) buffering. Using a process called Dynamic Video Memory Technology (DVMT), the
controller dynamically allocates display and texture memory amounts according to the needs of
the application running on the system.
