What kind of video processor is provided by the PowerBook G4 models? What is the maximum resolution each can support on an external display?

Every PowerBook G4 system is capable of supporting an external display both in "mirrored mode" -- where the contents of the internal display are presented identically on the external display -- and in dual display mode -- where the external display acts as a second workspace.

Information regarding the video system in each PowerBook G4 model is provided on the specs page for each system. However, for your convenience, this information also is provided in this handy chart below:
