Compatibility and safety notes
Choose HD15 or BNC based on the cable and source; BNC requires the correct separate RGB and sync assignment. Use a timing within the monitor's scan limits. The display is heavy and contains hazardous high voltage even when unplugged; do not open it or attempt internal adjustment without CRT service qualifications.
