The number above the screen was a piece of plastic to indicate the source (camera number), as this was a studio monitor with baseband composite input (no tuner). The "underscan" operation shown in the picture was selectable with a switch to show the complete image without corner cutoff. Part of the complication of studio monitors was to maintain linearity and convergence when in both underscan and "normal" modes.
