The Mitsubishi C-3919 is a 19-inch professional color display monitor manufactured by Mitsubishi Electric for use with the Advanced Electronics Design (AED) 512 and 767 Color Graphics Terminals. It features an in-line gun shadow mask CRT with self-convergence technology.
Features
The C-3919 is designed for high-resolution graphics display, capable of showing up to 2000 characters or 441,600 pixels. Key features include:
- Self-convergence design requiring no electrical convergence adjustments
- Switchable 75Ω / high-impedance input termination for daisy-chaining multiple monitors
- Anti-spark circuit protection
- Stable convergence with less than 0.5mm deviation in the center and 0.8mm elsewhere
- Video amplifier frequency response of ±3dB from 50Hz to 20MHz
- Rise and fall times shorter than 20ns
- Warm-up time of 20 minutes maximum
The monitor supports both sync-on-green (RGsB) and separate sync (RGBS) configurations via its BNC inputs.
Specifications
- Video input levels: 0.7–1.5 Vp-p for RGB, 1.0–5.0 Vp-p for sync
- Blanking time: Horizontal <9.5μs, Vertical <0.8μs
- Raster size regulation: <4mm change with 0–200μA beam current
- Linearity: Better than ±7%
- Raster distortion: Less than 2% of raster height
