 Well-known examples of early monochrome monitors are the VT100 from Digital Equipment Corporation, released in 1978, the Apple Monitor III in 1980, and the IBM 5151, which accompanied the IBM PC model 5150 upon its 1981 release.The 5151 was designed to work with the PC's Monochrome Display Adapter (MDA) text-only graphics card, but the third-party Hercules Graphics Card became a popular companion to the 5151 screen because of the Hercules' comparatively high-resolution bitmapped 720×348 pixel monochrome graphics capability, much used for business presentation graphics generated from spreadsheets like Lotus 1-2-3.This was much higher resolution than the alternative IBM Color Graphics Adapter 320×200 pixel, or 640×200 pixel graphic standard.
