Monitor accepts separate Horizontal, Vertical sync,
composite sync, and SOG.
Monitor accepts positive and negative sync. signal from
both 3.3V and 5V TTL families. Inputs sense a logic 0
when the input absolute value is 0.8 V or less and logic 1
when the input absolute value is 2.3V or greater.
2.2KOhm min (pull down)
Detachable, shielded 2.0 meters (6.67 ft), D-SUB 15P
male connector, with blue connectors, thumb screws and
black color.
Detachable, DVI-D, white connectors, 2.0 meters (6.67
ft) and black color.
S-VIDEO, COMPOSITE-video, w/o audio. Cables are not
included.
The monitor cannot be damaged by improper sync, timing
pulse duration, or absence of sync, or abnormal input
signal amplitude (video and/or sync too large or too
small), or any other anomalous behavior of a graphics
card or video generator when changing modes, or when
any combination of input signals is removed or replaced.
Additionally, under these conditions, the monitor cannot
cause damage to the source.
Image is considered to be ready for correct position and
timing adjustment after 3 minutes maximal warm-up time.
Horizontal frequency range: 31 to 80KHz
