PAL-M and NTSC color systems available
The monitor can display PAL-M, NTSC signals. The
appropriate color system is selected automatically.
® 1)
HR (High Resolution) Trinitron picture tube
The HR Trinitron picture tube (0.25 mm aperture grill
pitch) provides a high resolution picture. Horizontal
resolution is more than 450 TV lines at the center of
the picture.
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 fine
picture detail without color spill or color noise.
Multiple input signals
In addition to the composite video signals and the Y/C
signals, analog RGB signals and component signals
can be input.
External sync input
When the EXT SYNC button is pressed, the monitor
can be operated on the sync signal fed through an
external sync connector.
Blue only picture
Black and white apparent picture consisting from only
the blue signal will be displayed. This facilitates the
"chroma" and "phase" adjustment, and the observation
of the video noise.
16:9 selector
The monitor can display the 16:9 signal with the
correct ratio of width and height, compressing the
picture vertically.
Under scan mode
The monitor can display signals that are scanned
outside the normal screen so you can monitor the
whole image.
Audio circuit and built-in speaker

for sound monitoring.

The screen is automatically demagnetized when the
monitor is turned on. Manual degauss is also available
by pressing the DEGAUSS button.
Automatic termination
(only connectors marked )
The Y/C, VIDEO IN and EXT SYNC IN connectors

75-ohm termination is automatically released.

the monitor can be mounted in an EIA standard 19-
inch rack. For details on mounting, see the instruction
manual of the MB-507.

external DC 12 V power. The monitor can operate with
one or two Sony NP-1B* battery packs. If you use the
DC-L10* battery adaptor, the monitor can operate with
a Sony BP-L60A/L90A* lithium ion battery pack.
