The IIci’s internal video can drive a single-scan (a.k.a. fixed resolution; sync on green) monitor at 640×480 pixels with 8-bit color (256 colors). It can also drive a mono single-page display. The video circuitry uses up to 1 MB of RAM in Bank A as video memory (VRAM). This means that there must always be memory in Bank A, and it is best to leave the smallest SIMMs in this bank to speed up video performance.
