The Panasonic BT-LH910G is a portable, high-resolution LCD video monitor with advanced broadcasting functions. Its newly developed 23 cm (9 inches) New IPS LCD panel boasts the best-in-class (*1) WXGA (1280 x 768) resolution, high brightness and superb contrast, for use in applications that far exceed those of conventional compact monitors.
The BT-LH910G also offers extensive display functions, like an RGB WFM, a colour audio level meter and Focus Assist, to respond to diverse production and broadcasting needs. Using two SDI input terminals, the BT-LH910G can overlay the left-eye and right-eye images of a 3D source. Plus, it's equipped with a variety of 3D Shooting Assist (*2) functions.
From outdoor and studio recording to OB van installation and sub-monitor use for live broadcasting, the BT-LH910G meets high-end production and broadcasting needs.
When used as an electronic viewfinder, the BT-LH910 can be configured with Panasonic’s full range of HD shoulder-mount cameras, using the optional BT-CS910 viewfinder cable. The 12V DC-powered monitor is equipped with both a 4-pin XLR DC input and an Anton Bauer battery gold mount, making it ideal for outdoor use.

WXGA (1280 x 768), the Highest Resolution in the Portable Monitor Class
The New IPS LCD panel features a new pixel structure that heightens resolution more than 20% in terms of area ratio as compared with Panasonic's previous model BT-LH900A. This 23 cm (9 inches) LCD panel has 1280 x 768 pixels, which rivals the number of pixels in the 43 cm (17 inches) BT-LH1710 LCD monitor. The BT-LH910G offers the highest level of resolution in the portable monitor class, and opens the door to new applications in HD recording, production and broadcasting by surpassing the limits of conventional small monitors.
High Brightness, Superb Contrast, Wide Viewing Angle
The new pixel structure incorporated in the New IPS LCD panel has dramatically improved the light transmittance of the LCD panel, for greater brightness. New liquid crystal materials and newly designed colour filters have also achieved high contrast to render crisp, clear images. Together, they provide easy-to-see images even for outdoor viewing. The wide viewing angle of 176° in both vertical and horizontal directions is the best among LCD displays available today. The New IPS LCD panel boasts superb colour display characteristics with minimal changes in brightness or colour even when viewed at an angle.

The New IPS LCD panel features an LED backlight. Developed with advanced technology, this mercury-free panel also helps to preserve the global environment.
High-performance Image Processing Engine for Superb Moving Image Quality
- Precise 10 bit image processing uses a three-dimensional LUT (Look Up Table) for each RGB colour to achieve faithful colour reproduction from low to high brightness levels.
- The diagonal line compensation circuit minimizes jagged noise on diagonal lines.
- The high-speed, high-performance I/P conversion circuit achieves superb motion response with a delay of less than one field between input and panel display.
- Improved response time in intermediate gradations provides vivid and clear image displays without blurring.
Gradation and RGB Manual Adjustment
In order to match the LCD monitor to professional broadcasting applications, compensation is conducted for each monitor in 256 discrete RGB steps, and rated gamma properties (g = 2.2) are reproduced. The colour temperature can also be set to 9300K, 6500K or 5600K, and manual white balance lets you directly adjust gain and bias for R, G and B.
Calibration Function
The BT-LH910G comes installed with software that allows it to be calibrated without using a PC, by simply connecting a manufacturer-designated display colour analyzer and measurement probe to the monitor.

Diverse 3D Camera Assist Functions
When the left-eye and right-eye video signals from a 3D camera are connected to the two SDI input terminals, the BT-LH910G lets you check 3D images on its 2D display. The BT-LH910G is also provided with a variety of functions to help adjust a rig-type 3D camera system. It helps to reduce preparation time for 3D shooting and boosts image accuracy.
- 3D Assist Functions Supported by Various Formats
1080/60i, 1080/59.94i, 1080/50i, 1080/25PsF, 1080/24PsF, 1080/23.98PsF, 1035/60i, 1035/59.94i, 720/60p, 720/59.94p, 720/50p
- Mirror:
The Mirror function simplifies the basic adjustments of a rig-type 3D camera system. With the left-eye and right-eye images displayed side-by-side on the screen, the right-eye image can be flipped in the horizontal or vertical direction.
- Shift:
This function lets you move only the right-eye image horizontally or vertically in the overlay display. It's handy for checking angle misalignment between the left-eye and right-eye images.
- Comparison:
The Comparison function displays half-tone markers inside the left-eye and right-eye images displayed side-by-side. It lets you confirm that there are no missing image segments at the frame edge of only one image.
- Convergence:
With the left-eye or right-eye image displayed on the full screen, the Convergence function lets you switch the images automatically or manually. This makes it easier to confirm the convergence point.
- Colour:
The Colour function combines left-eye and right-eye images and displays them in a checkerboard pattern on a full screen. It allows you to check the brightness and colour variance between the two images.
- Zoom Focus:
This function enlarges and displays a section of images displayed side-by-side. It can be used to check the variance in focus and zoom between the left-eye and right-eye images. Focus-in-Red can also be used together with this function.
- VerticalL:
The Vertical function lets you closely inspect vertical misalignment between the left-eye and right-eye images using an auxiliary horizontal-line marker.
- Overlay:
Using this function, you can check the width of the left-right disparity by superimposing a vertical-line marker (in 3% intervals) on the overlay display or difference image between right and left in black-and-white display.
*The Overlay display on the BT-LH910G does not provide 3D effects even if 3D Eyewear is worn
