Display: 140x192

140x192x16 on Apple II
Early Apple II systems were limited to 6 colors in "HiRes mode" (280x192). 15 Colors were available in "LoRes" (40x48). Digitally, there were 16 colors but one was a duplicate color due to the nature of an analogue signal in the video hardware. This could be hacked for 1 additional color, again, in LoRes mode. But complex manipulation of the graphics hardware allowed 15 colors to be achieved when using double-width pixels in HiRes mode. Coupled with a more precise version of the color hack, 16 colors could be used as well. This required manipulating data directly on a machine-code level (which could be done through high-level languages). The result was a 140x192x16 software mode that could be addressed by high-level languages as if it were a hardware mode.
