2.4-5.5V, and low level will be 0-0.2V.
(3) Video Signal Level
The video signal when terminated with an idea 75ohm termination will have a
range of 0V to 0.7V (normal), and its full scale output will be 0.7V and black level
will be between 0V and 0.1V.

2.1.5 Signal timing
(1) PC synchronization :
(A)Horizontal frequency range: 31 to 60KHz
(B)Vertical frequency range: 56 to 75 Hz
(C) Type : Display accepts separate Horizontal, Vertical sync, composite sync,
and SOG.
(D) Level: Display 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.
(E) Impedance : 2.2KOhm min (pull down)
(F) Abnormal signal immunity : 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,
