Video: Dell ™ OptiPlex ™ G1 Systems
All systems include an integrated, high-performance, 64-bit accelerated graphics port (baseline AGP) subsystem that drives an external SVGA monitor. The AGP is a
dedicated bus that bypasses the PCI bus and allows for interconnection of the video subsystem directly to the Pentium ® II microprocessor's chipset, resulting in the
high performance required for 3D video subsystems. This architecture also off-loads video data from the PCI bus, providing greater performance for devices attached
to the PCI bus.
The maximum supported resolution is 1600 x 1200 pixels with 256 colors (8 bpp) at 75 Hz. Other supported resolutions are listed in Specifications . The SVGA
subsystem has the following major components:
l ATI 3D Rage II C (baseline AGP) SVGA video controller
l 2-MB SGRAM video memory (expandable to 4 MB)
l ATI Multimedia Channel (AMC) connector
l 15-pin monitor connector
