What graphics capabilities are provided by the Power Mac G3? Which have DB-15 and which have VGA ports? What is the maximum supported resolution on a primary and secondary display?

As shipped, all Platinum/Beige Power Mac G3 models are equipped with ATI 3D Rage II+, Rage Pro, or Rage Pro Tubo onboard video and a DB-15 video port and all "Blue & White" Power Mac G3 models are equipped with an ATI Rage 128 GL video card with 16 MB of VRAM and a VGA video port.

However, as all Power Mac G3 models have PCI slots, it is possible to support a secondary display by adding a second video card and some Platinum/Beige Power Mac G3 models shipped with a second video card by default. Additionally, the Platinum/Beige models have a single expansion slot that supports an additional 4 MB of VRAM (3.3V 83 MHz 144-pin SO-DIMM).
