• The LCD monitor is manufactured with high-precision technol-

ogy and has an effective pixel count of 99.99 % or more. How-

ever, less than 0.01 % of pixels may be stuck or dead. This is 

not a malfunction and does not affect recorded images.

• If a still image is displayed for an extended period of time, it 

may generate a temporary afterimage (phosphor burn-in). 

(However, afterimages can be removed by displaying normal 

video for a while.)

• LCD response speed and brightness vary depending on the 

ambient temperature.

• Do not install the unit where it will be exposed to direct sunlight. The 

cabinet may deteriorate and the LCD screen may be damaged.

• Do not install the unit in locations where enough space cannot 

be provided around it as heat may build up inside, preventing 

normal operation. Be sure to provide at least 80 mm (3-1/8″)

of space from the rear of the unit.

• Exposing the LCD screen to intense light sources will impair 

its characteristics and lower image quality.

• In an environment exposed to drastic temperature fluctuations, 

condensation may build up on and inside the LCD screen. This 

may lower the quality of the screen and cause a malfunction.

• There may be some unevenness on the screen depending on 

the image displayed.

• Leaving the unit in a location exposed to high temperature and 

humidity for an extended period of time may impair the char-

acteristics of the LCD screen and cause unevenness.

• Streaks of light may be seen in the area between the edge of the 

screen and the frame but this is normal and not a malfunction.

• Protective material is attached to the front to protect the LCD 

panel from damage during removal from the packing box and 

transportation. Remove it before use.

• This unit does not support VIERA Link. If the unit is connected to 

a VIERA-Link-compatible device with an HDMI cable, the VIERA 

Link functions of the other device may not operate properly.

• If the unit is used near a wireless transmitter, high-voltage 

equipment,  speaker, large motor, or other device or exposed 

to static electricity, the audio and video may be distorted by 

electromagnetic waves.

• Do not install the unit in a location that is 2 000 m (6561′ 1/8″)

or more above sea level.  

Doing so may affect the lifespan of the parts and result in a 

malfunction.

• Do not install the unit outdoors.  

Use the unit indoors.

• For the DisplayPort cables, use DisplayPort cables that com-

ply with the DisplayPort standard. 

Using a cable that does not comply with the DisplayPort 

standard may result in incorrect operation such as video being 

interrupted or not being displayed.

• For the HDMI cables, use HDMI High Speed cables that com-

ply with the HDMI standard.  

Using a cable that does not comply with the HDMI standard 

may result in incorrect operation such as video being inter-

rupted or not being displayed.

The unit is an LCD monitor for industrial applications, equipped with a 78.9 cm (31.1″) (effective display area) LCD.

 

„

• The unit incorporates a full 4K (4096 x 2160) LCD panel.

• It offers excellent color reproduction, a wide viewing angle, 

and a fast response time.

 

„

•  The implementation of 10-bit for all signal circuit process-

ing as well as 3D look up table (LUT) image processing 

facilitates accurate and smooth gradation from low to high 

brightness levels.

•  Support for digital cinema DCI (P3)

*

 in addition to color 

space (SMPTE-C/EBU/ITU-709) allows you to also use the 

unit for cinema production applications.

• Gamma compensation is performed for each monitor.

 u' v' coverage: 96 %

 

„

•  The unit is equipped with four 3G/HD-SDI lines, two HDMI 

lines, and two DisplayPort lines.

•  FOCUS-IN-RED function 

Focusing the camera is extremely easy because the area 

of the image in focus is displayed in red or another color to 

make it easy to see what is in focus.

•  LUT upload function 

Color conversion data generated by a color grading device 

or other device can be imported to the unit to enable the 

reproduction of the colors intended by your colorist.

•  4-screen display function (3G/HD-SDI inputs and same format)

-  The panel display area can be split into four to display four 

input signals independently.

-  The time code and audio level meter superimposed on each 

input signal can be displayed independently.

-  Camera adjustments can be simplified by simultaneously 

displaying FOCUS-IN-RED, WFM, and vectorscope based 

on one input signal. (MULTI FUNCTION)

-  One input signal can be displayed on four screens and you 

can independently change the gamma, color temperature, 

and color gamut or adjust the image quality on three of the 

screens. This function facilitates easy comparison with the 

original image to check the differences created by effects. 

(PICTURE ASSIST)

• Audio level meter display function

This function allows you to display the level of an audio signal 

embedded in a 3G/HD-SDI, HDMI, or DisplayPort signal.

Furthermore, support is also included for reference point set-

ting, peak hold, and overrange display.

The unit is equipped with a speaker and HEADPHONES output 

jack so you can check the audio. There is also a menu for 

selecting channels.

• Cross hatch display function

This function displays markers at regular vertical and hori-

zontal intervals to facilitate easy composition.

• External remote control

The unit is equipped with RS-485, RS-232C, and GPI 

remote control connectors. A daisy chain connection using 

the RS-485 input/output connectors enables the control of 

multiple monitors (up to 32 monitors).

• A robust metal frame has been employed to ensure the 

durability required for transportation.

• Support for DC driving means you can also operate the unit 

on batteries.
