The IBM 5151 is a 12-inch transistor–transistor logic (TTL) monochrome monitor originally bundled with the first IBM Personal Computer, designed specifically for use with the IBM Monochrome Display Adapter. It also supports compatibility with several other graphics adapters, including the Hercules Graphics Card.
This display incorporates an 11.5-inch diagonal cathode ray tube (CRT) featuring a 90-degree deflection angle and an etched anti-glare screen. It delivers a resolution of 350 horizontal lines at a refresh rate of 50 Hz. Connectivity is established through a 9-pin D-sub TTL digital interface, allowing for multiple brightness settings by utilizing different signal pins. The monitor receives power directly from the IBM PC’s power supply, which means it does not have an independent power switch.
Employing P39 phosphor, the IBM 5151 produces a vivid green monochrome image tailored for crisp text rendering at high resolution. The high-persistence nature of this phosphor minimizes flicker but may introduce smearing effects during fast-moving graphics.
