Diamondtron®RDF225WG
Ultra-wide color gamut CRT monitor
with SpectraViewTMWG Color Calibration Solution
Mitsubishi Diamondtron CRT technology.
The ultimate color performance for high-end professional users.
For high-end, professional applications such as medical imaging
and publishing, a wide and accurate color spectrum is vital in
achieving your desired output. Mitsubishi has furthered the range
and depth of CRT display color reproduction with its ultra-wide
color gamut 22" (20" viewable image size) Diamondtron
RDF225WG monitor. With this revolutionary display, it’s now a
snap to realize high-performance color reproduction for even your
most demanding applications.
The ultimate in color performance. Recent technology advances
in digital image acquisition, color-processing systems, color printers and other photographic I/O devices have been nothing short
of remarkable. In addition to startling resolutions, the range and
depth of color reproduction also has shown significant improvements. A standardized color space promises the benefit of guaranteed color reproduction across all digital platforms and devices
from the point of acquisition to the point of delivery, over a wide
range of colors. Traditionally, a standardized color space with a
wide color gamut required sophisticated hardware technology
and was generally found only in professional DTP, pre-press, color
proof-matching or color management system environments.
There have been alternative color spaces with reduced palettes,
which offer compatibility to a wide range of consumer devices.
The most widespread is called sRGB, which is a color space standard and well-promoted and widespread in consumer electronic
applications, such as digital cameras, PC operating systems, PC
color monitors and desktop printers. Adobe
ed color space, promoted by Adobe, which over time has
become a de-facto standard in the professional color processing
market. Through its widespread adoption, compliance with the
Adobe RGB color space ensures cross-compatibility with a wide
range of high-end professional digital color devices, cameras,

scanners, digital transmission and printing process systems.
However, due to the onerous requirements, compliance has
been virtually impossible for most electronic displays; the digital chain has been incomplete.
The RDF225WG represents an exciting development in material
science in bringing an Adobe RGB-compliant display successfully
to market. The key materials-science innovation has been the
development of a new high-persistence phosphor, which can
extend the display color gamut to a close approximation of the
Adobe RGB color space. With its improved CRT phosphor, the
RDF225WG extends the color space to 97.6% of Adobe RGB for
more accurate, consistent and repeatable color performance compared to conventional CRT displays that cover only 70% of this
industry standard.
Flat-out better screen performance. Using the latest in
advanced flat-screen technology, the RDF225WG delivers the
ultimate screen performance to your desktop, enabling you to
develop stunning creations without having to second-guess

experience.
Diamondtron, the latest generation of flat aperture grille CRT technology, provides exceptional
performance with unprecedented focus and contrast and a virtually flat image that reduces distortion and glare. This CRT technology also delivers better brightness uniformity for consistent,
true-to-life images and improved color saturation. With this kind of performance, what you see
on-screen is as life-like as what you see on your
printed output. Further, superb frequencies allow
for better resolutions and one of the industry’s
highest refresh rates.
Enhanced clarity and focus. The RDF225WG fea-
tures the Mitsubishi U-NX electron gun that
includes an additional lens to improve the
monitors’ focus and convergence. An electron
beam, which is projected through the multiple
lenses and onto the viewable image area, produces a small beam spot, achieving better
focus and clarity at higher resolutions. The larger main lens reduces distortion and potential
image halo effect.

Channel/Command Interface (DDC/CI). This
allows control commands to be sent directly to
the monitor by the local system or remotely over
an existing network (LAN) by a system administrator. In order to take full advantage of these
benefits, users must use a DDC/CI-compatible
graphics card and be running Windows 2000/XP.
User-friendly, minimalist design. In developing
the RDF225WG, our engineers focused on its
smooth integration into work and home environments. Featuring reduced cabinet size and
bezel width as well as recessed cable connections, this monitor has been designed for easy,
flexible integration into a variety of surroundings, including cramped areas and ergonomically challenged work spaces. This user-friendly
design enables you to focus more on what is
on-screen, enhancing not only your visual experience but your overall productivity. ErgoDesign
enhancements, which include a tilt/swivel base
that easily adjusts to each user’s preferred
angle of vision, further increase comfort, productivity and ease of use.
Quality and service you can count on. You can
rest easy knowing that NEC-Mitsubishi is available 24 hours a day, 7 days a week for technical
support, and a 3-year limited warranty guarantees your satisfaction.
SpectraView WG
Color Calibration Solution
Unrivaled color performance for sophisticated
professionals. In today’s graphics environ-
ments, color accuracy is critical. To help meet
the needs of even the most demanding creative
professional, the RDF225WG ships with the
SpectraView WG Color Calibration Solution,
which delivers superior display and color performance to your desktop. In addition to the
flat-screen CRT monitor, this state-of-the art calibration solution includes intuitive software, a
calibrator and hood.
Simple measurements in no time. SpectraView
WG achieves precise color calibration with actual
on-screen color measurements using a tri-stimulus colorimeter and custom software that provide
the necessary link between your input and output devices. Adjustments are made directly to
the monitor electronics by way of the DDC/CI
communications channel. This state-of-the-art
digital technology provides the ability to control
the RGB gains, resulting in better luminance,
black colors and, overall, more accurate calibration when compared to systems that only use the
video card to make adjustments. The monitor’s
digital control also delivers quicker measurement
times, more frequent calibration routines and a
reduced chance for human error when making
adjustments to screen settings. Using three 24bit analog-to-digital converters, SpectraView WG
measures color at five measurements per second
®
either at absolute white or black. These phasedlock measurements are achieved at a rate that is
up to 2-5 times faster than other competitive
desktop color sensors.
Reliable color-matching. Because each device
displays color differently, what you see on screen
may vary significantly from what you see in your
output, resulting in expensive and time-consuming guesswork. The SpectraView WG system
accurately measures the color on your display
and seamlessly creates a reusable ICC profile of
that monitor’s color to provide consistency.
Furthermore, the system assists in matching colors from monitor-to-monitor as well as to peripheral devices such as printers and scanners.
Advanced, accurate light measurement.
SpectraView WG quickly and easily calculates
optimal display characteristics. Similar to more
expensive light measurement instruments, the
calibrator features three color sensors. Compared
to single-sensor models that only measure overall light intensity, this results in more accurate
calibration because the display’s individual red,
green and blue phosphors are measured sepa-
