SECTION 1
GENERAL
The operating instructions mentioned here are partial abstracts from
the Operating Instruction Manual. The page numbers of the
Operating Instruction Manual remein as in the manual.
1-1. GENERAL OF PVM-1450QM
Features
Fine Pitch Trinitron picture tube
Fine Pitch Trinitron tube provides a high resolution picture.
Horizontal resolution is more than 450 TV lines at the center
of the picture.
Four color systems available
The monitor can display PAL, SECAM, NTSC and
NTSCH3* signals. The appropriate color system is selected
automatically.
* A signal of NTSCw is used for playing back NTSC
recorded video cassettes with a video tape recorder/
player especially designed for use with this system.
Analog RGB input connectors
Analog RGBsignals 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,
assuring video quality.
Beam current feedback circuit
The built-in beam current feedback circuit assures stable
white balance.
Comb filter
When NTSC video signals are received, a comb filter
activates to increase the resolution, resulting in fine picture
detail without color spill or color noise.
Automatic termination
(connector with 1\/v-mark only)
The input connector is terminated at 75 ohms inside when
no cable is connected to the loop-through output
connectors. When a cable is connected to an output
connector, the 75-ohms termination is automatically
released.
Blue only mode
In the blue only mode, an apparent monochrome display is
obtained with all three cathodes driven with a blue signal.
This facilitates color saturation and phase adjustments and
observation of VCR noise.
Auto/manual degaussing
Degaussing of the screen can be performed automatically
when the power is turned on, or manually by pressing the
DEGAUSS button.
On-screen menus
You can set CHROMA SET UP and other settings by using
the on-screen menus.
Five menu languages
You can select the menu language from among the five
languages on the menu.
EIA standard 19-inch rack mounting
Byusing an MB-502Bmounting bracket (not supplied), the
monitor can be mounted in an EIA standard 19-inch rack.
For details on mounting, see the instruction manual of the
mounting bracket kit.
