FEATURES
SUPERB PICTURE QUALITY
High resolution, brightness,
and contrast
CONVENIENT OPERATING FUNCTIONS
Independent brightness and
color uniformity adjustments
Excellent uniformity from screen
corner to corner is assured with the
brightness and color uniformity
adjustments. Moreover, these two
adjustments can be performed
independently; this means that
extremely even and precise
adjustments can be made across
the entire screen.
Picture orbiting function
Similar to "screen saver" functions for
computer monitors, Sony's Picture
Orbiting feature reduces the risk of
CRT burn in projectors. CRT burn is
caused by prolonged still-image
projection. The orbiting function
rotates the projected image in
intervals which cannot be detected
by the human eye.
Power saving mode
To protect the environment, power
consumption can be reduced when
the power saving mode of the
VPH-G70Q/G70QM is set to on.
The combination of numerous
advanced technologies including
newly developed 8-inch
electromagnetic focus CRTs, new
hybrid HACC lenses and a 120MHz
RGB bandwidth is your assurance of
a high resolution of 1700 x 1200 dots
and a high brightness of 240 ANSI
lumen. Both a wide RGB bandwidth
and high brightness are achieved by
incorporating an advanced CRT
drive circuit, which assures
uncompromising reproduction of the
highest frequency computer images.
In addition, the liquid contained in
When the projector detects that there
has been no input signal for over 10
minutes, it automatically enters
power saving mode. The projector
quickly returns to full operation as
soon as an input signal is detected.
Multi-language on-screen
menu
The multi-language on-screen menu
is provided to simplify operations.
The on-screen menus can be
selected in any of seven languages:
English, French, German, Italian,
Spanish, Japanese or Chinese.
Simplified operation for multi-
projection applications
ABL link function
In order to prevent CRT damage,
the VPH-G70Q/G70QM has an
Automatic Brightness Limiter (ABL).
This circuitry controls the beam
the universal optical coupling
enables the projector to provide high
picture contrast for exceptionally
accurate picture reproduction.
Multiscan capability
The VPH-G70Q/G70QM accepts
signals within the wide range of
fH: 15 to 110kHz and fV: 38 to 150Hz.
Even if the horizontal frequency of
the input signal changes from one
end of this range to the other, the
VPH-G70Q/G70QM handles this
change with a minimum of
disturbance.
current so that it remains below the
point where CRT damage may occur
and overall screen brightness is
affected. The ABL Linkage function
is designed especially for multi-
screen displays. If the ABL circuit is
activated on any one projector in a
multi-projector installation, then the
beam current in all of the other
projectors is similarly modified so
that uniform brightness over the
whole of the projected image is
maintained.
Index operation
An index number can be assigned
to each VPH-G70Q/G70QM to
facilitate operation and adjustment
of individual projectors in a multi-
projection application.
Loop-through remote
connectors
With the supplied IFB-40 Interface
Board, multi-projector remote control
is easy and convenient for double
and triple-stack applications. Simply
connect a SIC-M cable from the
14-pin output connector of one
projector to the 14-pin input
connector of another.
Optional internal line-doubler
board
The visibility of scanning lines—
especially noticeable in large screen
reproduction—is greatly reduced
and images are solidly reproduced
with the optional internal Sony
EXB-DS10 IDTV Board which also
features motion compensation.
