Replaced with New Product

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 II


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 color model.


*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.


Calibration function


Calibrates luminance and gamma to enable smooth grayscale display that is faithful to DICOM GSDF.

 * 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 to portrait.



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 specialized settings.

 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 calibration settings.


LED indicator to inform of current status


A glance at the LED indicator tells you the display’s current operating status.




Display Quality Control


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 order 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.


Gamma check

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.




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.
