Panasonic BT-4LH310

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.

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
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).
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.

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

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.
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.
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.
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. Upto 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.
