2MP with Independent Sub-pixel Drive Technology
21.3" Digital Monochrome Display
Excellent image reproduction with Independent Sub-pixel Drive technology beyond panel’s normal capability
Cost-effective medical display
- Independent Sub-pixel Drive technology (patent pending) to provide the highest resolution ever
- Next-generation interface "Displayport."
- Switching function between luminance and gamma
- Advanced display quality control
- Uniformity equalizer to minimize luminance and color unevenness across the
- Hardware pivot function for fast drawing vertically
- AR-coated models to provide accurate image reproduction
- Built-in and energy- saving power supply
High resolution of 6M sub-pixels realized by Independent Sub-pixel Drive technology
Faithful Reproduction of Image Details
While a pixel pitch of 2MP displays is 270µm,
90µm in sub pixel chain direction by newly developed Independent Sub-pixel Drive technology to realize excellent
depiction of image details.
Advanced Image Quality with Less Degradation
To display an overall image whose native resolution is higher than the monitor
is able to reproduce, the image is converted to a lower resolution image with
a certain amount of data loss.
The MS23i2 with super high resolution offers excellent image reproduction,
faithful to the original captured by the modality device with less image degradation.
Independent Sub-pixel Drive Technology
Driven each sub-pixel value corresponding to detailed
information recorded in an original image, three times resolution enhancement
is achieved. (Patent pending)
In addition, up to 1276 shades of gray are now simultaneously displayable by
the upgraded Independent Sub-pixel Drive technology.
*Customized viewer software is required to display images with enhanced resolution
by the Independent Sub-pixel Drive technology.
Special AR Coating for Film-like Black and Improved Sharpness
TOTOKU's new special AR coating technology addresses properties of focus, noise
reduction, contrast, and viewing angle achieving film-like black and accurate
reproduction of images. (Patent pending)
Luminance stabilizing system λ-Sentinel
λ-Sentinel II consists of a luminance sensor and luminance control circuit. The
luminance sensor, integrated into the front bezel, consistently monitors and
accurately stabilizes luminance on the screen by rapidly communicating with
the backlight sensor.
In addition, a build-in luminance sensor provided with i2 models enables
even simpler calibration without attaching the calibration sensor.
Simultaneous display of 2048 shades of gray
Combined with a viewer software, 2048 shades of grapy (11 bit) can be simultaneously
displayed. It realizes smoother grayscale display required for medical image displays.
*A viewer software that supports TOTOKU's multi-shade display system is required
for 2048 shades of gray simultaneous display.
*1276 shades of gray are simultaneously displayable by the Independent Sub-pixel Drive technology.
Remote grayscale check and remote calibration functions
Conformance testing to DICOM GSDF and calibration can be remotely accomplished.
These features minimize the burden on display administrators.
* Optional PM Medivisor software is required.
Next Generation Interface - DisplayPort
In addition to a DVI port, each i2 series display includes a new digital display
interface, "DisplayPort". When using the DisplayPort, up to 1024 or 10-bit shades of gray are simultaneously displayed. This enables smooth and accurate
display of subtle dierences in shades of gray. Additionally, 1073.74million colors (10-bit in each R, G, B) are simultaneously displayed on our
*Customized viewer software and graphics card are required to display 10-bit images.
Luminance equalizer λ-Uniformity Congruence
Is built in to achieve highly accurate luminance uniformity across the screen. Luminance unevenness is minimized in the final tune-up prior to shipping.

* Optional calibration kit is required.
Hardware pivot function for fast drawing in portrait on landscape orientation
Stress-free operation is made possible by fast drawing speed for on-the-fly change
User-selectable display configurations
Luminance/gamma settings are selectable from three preset levels according to
the needs. User-selectable configurations enable stress free operations without
OSD Information Display
With a push of a button, the display's current status can be checked such as
the display model, total operating time, actual measurement of luminance, and
LED indicator to inform of current status
A glance at the LED indicator tells you the display's current operating status.
The Medivisor Series is a series of software to collectively support display
quality control from acceptance and periodic constancy testing to constant monitoring, to calibration.
Ecological Technology – Considering the Global Environment
Totoku is committed to providing high performance display systems that are ecological
and environmentally friendly. We strive to create green IT initiatives and
be a part of building a clean energy future. In eort to achieve this, we have
incorporated new power-saving features in our i2 series displays.
Our advanced power saving function dims the backlight as the screensaver activates,
thereby reducing power consumption and preventing unnecessary backlight deterioration,
resulting in a longer lasting display. Our internal power supply system includes
a newly improved power save mode, which allows the display to enter standby
mode with less than 2 watts of energy consumption.
*Optional software Calibration Kit is required to set up the Advanced Power Savings feature.
Enhanced convenience with utility software:
Advanced power saving*
The backlight dims as the screensaver starts, reducing power consumption and
preventing unnecessary deterioration of the backlight.
* This feature may not be available, depending on the specifications of the graphics card used.
18 points of luminance values are measured and plotted into a graph.
*Optional software Calibration Kit is
required to set up the Advanced Power Savings feature and Gamma check feature.
Pairing service to match colors of two displays (Optional)
Worldwide medical safety standards
This display is certified under various medical safety standards that are much more demanding than those for general-purpose IT equipment.
