Compliance with medical safety

standards in U.S.A., Canada and Europe

IEC 60601-1 and product safety standards in the U.S.A, Canada and Europe have been obtained for this monitor. The monitor is designed for use in the medical treatment field, with the sheet switch, screen protect panel, etc.


Fully digital 10-bit signal processing circuit

As well as digital signals, all signals including analog signals are converted into digital signals. All signals are processed using a fully digital 10-bit processing circuit so that an image is produced in smooth gradation without any deterioration of quality.

Two color system available

The monitor can display NTSC and PAL signals by connecting this unit.

Auto chroma/phase function

The chroma and phase of the decoder are automatically adjusted with the auto chroma phase function.

High image-quality/high-resolution WUXGA

LCD panel

An WUXGA high-resolution (1,920 × 1,200 dots) panel and high brightness/ultra-wide field of view technology enable you to use the monitor under various lighting conditions and in numerous ways (installing on wall, using several monitors to view an image, and so on.). Because a color filter with wide-color reproduction and LCD materials with high response speed are used, the motion picture of the video signal is displayed clearer. This monitor also performs sampling of signals at high frequencies and provides a high resolution of 700 TV scanning lines or more during the RGB or component

signal (480/60I, 575/50I) input.


Accepts analog RGB input signals

Adopting the scan converter allows this monitor to detect VGA, SVGA, XGA and SXGA analog RGB

signals input to the HD15 input connector.

Accepts DVI-D (digital) input signals

Adopting the scan converter allows this monitor to detect VGA, SVGA, XGA and SXGA digital computer signals input to the DVI input connector. The number of the DVI input connectors can be

increased by installing the optional input adaptor into the optional input port. To view more than SXGA signals when the DVI input is selected, use the cable within 3 m (118 ⅛ Inches) length..

Optional port

Two optional input adaptors can be installed. The composite, Y/C, component, analog RGB, SDI or DVI-D signal can be input depending on the input connectors of the board to be used. SDI supports not only HD-SDI and SD-SDI, but also 3G-SDI, which transmits twice as much data as HD-SDI with a Single-link.


NTSC or PAL color system or DTV format, such as 720P, 1080i, etc. can be selected automatically.

External sync input

The unit can be operated on the sync signal supplied from an external sync generator.


APA (Auto Pixel Alignment) function

You can display pictures from the HD15 input connector in the appropriate picture by simply pressing the APA key.

Automatic termination (connector with

mark only)

The input connector is terminated internally at 75 ohms when nothing has been connected to the output

connector. If a cable is connected to the output connector, the internal terminal is automatically

released and the signals input to the input connector are output to the output connector (loop-through).

Select color temperature and gamma mode

You can select the color temperature from among three (HIGH, LOW, LOW2) settings and gamma mode from between two settings (2.2, DICOM). You can also adjust the color temperature to the appropriate setting in “USER”.


Two kinds of input signals are put on the monitor.

Color space feature

You can select ITU-R BT.709 for the color space settings.

Aspect setting

You can set the monitor to 4:3 or 16:9 display mode according to the input signal.

Scan function

You can select the display from among “NORMAL”, “OVER”, “FULL” and “NATIVE” except the HD15 and DVI input signals.

Select language display

You can select your language for the display from seven languages – English, French, German, Spanish, Italian, Japanese and Chinese.

Power saving function

The monitor enters into power saving mode to reduce the power consumption when no signal is input.

Key inhibit function

You can inhibit the key to prevent missing an operation.

User memory function

You can save the 20 picture settings with the name. The user memory data can be saved or loaded between the  monitor and the equipment (PC, etc.) connected in serial remote mode.

Two kinds of ground terminals

Two kinds of ground terminals are built into the monitor to equal the electric potential.

External remote function

The input signal is selected or various items are adjusted by use of the serial (Ethernet) remote function. You can connect this unit to the monitor by the Ethernet (10BASE-T/100BASE-TX) connection and controlled remotely on the network.


Optional stand

It is more convenient to install the monitor on a desk by using the optional stand (SU-560).
