Picture
Fine pitch Trinitron" picture tube
The fine pitch trinitron tube provides a high resolution
picture. Horizontal resolution is more than 500 TV
lines at the center of the picture.
Comb filter
When NTSC video signals are received, a comb filter
activates to make more accurate Y/C separation. This
contributes to less of a decrease in resolution, cross
color and cross luminance phenomena.
Beam current feedback circuit
The built-in beam current feedback circuit assures
stable white balance.
Four color system available
The monitor can display NTSC, PAL, SECAM and
NTSC." signals. The appropriate color system is
selected automatically.
Input
Analog RGB input connectors
(for PVM-14N2A/14N2E/1 4N2U/20N2A/20N2E/
20N2U only)
Analog RGB signals from video equipment can be
input through these connectors.
Y/C input connectors
The video signal, split into the chrominance signal (C)
and the luminance signal (Y), can be input through this
connector, eliminating the interference between the
two signals, which tends to occur in a composite video
signal, ensuring video quality.
Automatic termination
(connector with "~- mark only)
The input connector is terminated at 75 ohms inside
when no cable is connected to the loop-through output
connector. When a cable is connected to an output
connector, the 75-ohm termination is automatically
released.
