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.

High Image Quality to Meet 4K Image Production Needs
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

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.

Panasonic BT-4LH310
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.

• 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)

Diverse Functions for Easier Operation
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.
