Memory of 4 different of color temperatures
As the monitor is able to memorize other color
temperatures in addition to the D93/D65 color
temperatures set as default, the optimum white
balance can be set promptly, as well as, easily
according to the input image conditions and purpose
of use.
BFS (Beam feedback system)
By adopting a BFS circuit for detecting CRT cathode
current, stable black balance can be obtained for a
long period of time even when the CRT emission
changes.
Rich variety of internal test signals
The monitor is equipped with a variety of useful
test signals for adjustments such as crosshatch, flat
field (50%), window (100%), character, and staircase
waveform with pluge.
The format of the test signal can also be selected
from HDTV:1080i/1035i/720p, SDTV:480i/575i by
MENU settings.
Built-in markers
4:3 markers can be displayed on 16:9 images.
80%, 88%, 90%, 93%, 100% and other markers can
be displayed for the 4:3/16:9 aspects in NTSC.
Shadow function
While displaying pictures with an aspect ratio of
16:9, the monitor displays 4:3, 13:9, and 14:9 image
areas and creates a shadow (the shadow contrast is
set up to about 40%) at the other image portion. This
monitor is capable of viewing 4:3, 13:9, and 14:9
images simultaneously while monitoring 16:9 images.
As this shadow function can be turned on and off
by remote control, prompt switching is realized.
Degauss timer function
The degauss timer function sets the timer so that
auto degauss operations are performed automatically
about 4 seconds after the power is turned ON. The
timer can be set for each monitor at intervals of 0.5
seconds from 0 to 4.5 seconds.
This minimizes the rush current flowing when the
power of a system comprised of multiple monitors is
turned on at once.
Structure with enhanced maintenance and
expendability
The signal processing module (including optional
modules) is of the plug-in type which can be easily
disconnected and reconnected from the back without
having to remove any cover, thus allowing easy
maintenance.
Besides the analog component (YPbPr/RGB) module
the unit comes standard equipped with, up to 4 different
types of optional modules can be added for expansion.
Use of high performance in-line gun CRT
A high performance in-line gun CRT of 0.25mm dot
mask pitch is adopted to produce fine images with
reduced reflection of external light.
A black matrix screen realizes images of high
contrast with enhanced black purity.
Luminance compensation function by
image size
In the case of the CRT monitor, when the image
size is reduced from normal to under-scan or from 4:3
to 16:9 scan image size, the current density increases
to cause a change of luminance. This monitor performs
luminance compensation so that the luminance
remains constant even when any of the four image
sizes is changed.
HD 4:3 SCAN function
This function enlarges 4:3 image area only and
displays it in full screen (aspect ratio 4:3) during the
HDTV mode, thus allowing real-time monitoring of
the image that would be obtained after down-
converting to 4:3 aspect ratio of SDTV. During the
HD 4:3 SCAN, the size of the 4:3 image area is
magnified to the size comparable to the size of 24-inch
16:9 CRT screen.
High voltage regulation circuit
High voltage regulation circuit controls the pulse
for each scan line, thus realizing the high voltage
stability of ±0.5%. This regulation circuit ensures
quicker response and minimal distortion in high
luminance, resulting in an image of high stability.
Auto setup function
Use of the auto setup probe ASP-80 (optional)
enables automatic adjustment of the color temperature
easily.

Chroma upgrading function
The chroma control's maximum level has been
increased from +6 dB to +12 dB.
