      • The Apple IIgs supported all graphics modes of previous Apple II models and introduced several new ones through a custom Video Graphics Chip (VGC), all of which used a 12-bit palette for a total of 4096 possible colors, though not all 4096 colors could appear onscreen at the same time. The IIgs is officially compatible with the 12" (11.5" viewable) Apple RGB Monitor A2M6014. Other RGB monitors will work but they must support the IIgs analog signal. There were several third party monitors that were compatible with the IIgs, but all of them required a custom cable and ranged in size from 12" to 15". Compatible monitors have a fairly low horizontal sync rate - 15.75KHz.
