H If NTSC and PAL external references are configured
the same, the monitor automatically operates in the
same television standard as the
EXT REF input.
When NTSC and PAL external references are
configured differently, the monitor’s operating
standard is determined by the standard of the dis-
played video instead of the
EXT REF input. Once the
operating standard is determined, the monitor
immediately switches to the appropriate input for
reference timing.
