4K (4096 x 2160) Monitor

Panasonic introduces the BT-4LH310 787.4 mm (31 inches) 4K LCD monitor, to provide powerful support for 4K and 2K/HD

image production for broadcasting and cinema applications. The BT-4LH310 boasts stunning display resolution in both

4K (4096 x 2160) and QFHD (3840 x 2160). Its reference-level image quality and excellent color reproduction meet the DCI (P3)

color gamut standards. Its new LUT (Look Up Table) upload function (To be supported soon) also allows high-precision color

management in a digital cinema workflow. In addition, this LCD monitor comes with a variety of display functions to assist video

production, such as Zoom, Focus-in-Red and Y Map, as well as other handy functions that streamline production activities,

including Frame Grab and Error Indication. The rugged aluminum frame and AC/DC power capability ensure high mobility.

Color Matching

4096 x 2160 Resolution

Supports both 4096 x 2160
resolution (17:9 aspect ratio) and
3840 x 2160 QFHD resolution
(four times the resolution of
Full-HD). The LCD panel can be
used for 4K image production for
broadcasting and movies.

DCI (P3) Color Gamut

Surpasses the EBU TV color
gamut, and covers 96%
(u', v' conversion) of the DCI
(P3) color gamut for digital
cinema use. The LCD monitor
displays colors accurately. It has
a 100% color gamut coverage
for BT709, EBU and SMPTE-C.

New LUT Upload Function*

Capable of LUT (look-up table)
uploading. Brings high-precision color management to the digital
cinema workflow. When shooting, images can be checked on the
LCD monitor with the same color setting as that used for editing.

* A PC and LUT upload application software are required (to be supported soon). For more
information, visit the Panasonic website [http://pro-av.panasonic.net/].

IPS Panel with High Contrast, 10 bit and Wide Viewing Angle

• 1450:1 High Contrast: Delivers sharp, clear 4K images.

• 10 bit Panel: 10 bit processing produces 1,070,000,000 display

colors for extremely smooth gradation.

• 178° Wide Viewing Angle: Wide 178° viewing angle in both
horizontal and vertical directions. The high-quality image display
shows practically no color shift even when viewed at an angle of 45°.

3D-LUT and 6-Pole Color Correction

Eliminates color phase shifts (drift) in the LCD panel caused by
luminance level differences. By providing a look-up table for each
luminance level and applying 12 bit image processing to each RGB
color, it balances the six coordinate poles of the three primary colors
(RGB) and their complementary colors (CMY). This helps to
reproduce the intermediate shades of extremely fine colors.

Focus Assist

Equipped with Focus-in-Red and Zoom functions to help achieve
precise focusing when shooting with a 4K/2K/HD camera.

• Focus-in-Red: Emphasizes
the sharply focused area of the
image by showing it in an easily
visible red.

• Zoom (4K): Enlarges (4x normal
size) the center section of the
image or one of the quarter
sections and displays it on the full
screen for accurate, easy focusing.

Functions to Assist 4K/2K/HD Video Shooting

Luminance, Zebra and RGB Display Modes

• Y Map: Allows quick visual
confirmation of scene luminance
levels via means of assigning a
simple color code for each
luminance step, includes
reference chart.

• Zebra: Can be operated in the
same way as the Zebra function
of a camera viewfinder.

• RGB Color: The display of each
RGB color can be turned on and
off individually.

Markers and Grid

• Aspect Marker: Capable of
indicating an image area in one of
up to eight aspect ratios (16:9
(only when 17:9 is set), 4:3, 13:9, 14:9, CNSCO2.39, CNSCO2.35, 2:1
and VISTA).

• Safe Area Marker (17:9/16:9/4:3): 95%, 93%, 90%, 88%, 80%,
USER, DOT/ LINE or VAR marker (selectable)

• Center Marker: Can be displayed together with another marker.

• Cross Hatch Grid: Allows easy checking of camera tilt.

New Quad Display (2K/HD)

Taking advantage of 4K resolution, the Quad Display function
displays a waveform monitor (WFM) and a vector scope (VSC) as
well as one of the Focus-in-Red, Y Map and Zebra assist functions
simultaneously with a full-pixel image from a 2K (2048 x 1080) or
HD input source. This function also allows a single BT-4LH310 to
be used as four 2K/HD monitors. It displays full-pixel images
without resizing.

* WFM/VSC cannot be displayed with a 4K signal input.

New Frame Grab

Frame grab allows for a still image to be captured from video and
displayed on the monitor. This function is useful for comparing
camera angles or colors between takes or scenes.

New Error Indication

Transmission and other
errors are detected during
SDI input, and the error
status is displayed and
logged.

Audio Level Meter

The audio level meter can be overlaid on the displayed image. Up
to eight channels can be simultaneously displayed. A peak hold
function is included. For 3G-SDI input, channels 1-8, or channels
9-16 can be selected.

Time Code/Closed Caption (2K/HD) Display

The time code display shows the UB value on one line and VTC/UB
or LTC/UB simultaneously on two lines. The closed caption
function supports EIA/CEA-708 in compliance with HD SDI CC
standards.
