18.5" High-Performance HD/SD LCD Widescreen Monitor

BT-LH1850E

The BT-LH1850 is an 18.5" high-performance HD/SD LCD production monitor with full 1366 x 768 resolution and impression new features including an HD and SD closed caption display, vectorscope, waveform monitor for R/G/B signals, an RS-485 serial remote, and an eco-friendly panel with mercury-free LED backlight that provides remarkably low-power consumption, (22W, representing a more than a 50% reduction from the prior LH series model). With HD and HDMI connectivity, the versatile LH1850 also offers a 3D look-up table (LUT), which produces faithful  colour hues and smooth gradation, together with quick-response motion images.

The WXGA-resolution LH1850 delivers the professional features and outstanding price-to-performance users have come to expect from a Panasonic LH-Series monitor. And now Panasonic adds additional versatility in the LH1850, including the ability to view any camera source with an HD/SD SDI or HDMI output, and the display of HD and SD closed captioning.

The LH1850's 3D-LUT with 6-pole  colour correction includes a look-up table for each signal level, and applies 10-bit image processing to each RGB  colour to balance the six coordinate axes of the three primary  colours (RGB) and their complementary  colours (CMY), resolving  colour drifting at low light levels and keeping  colours vividly natural. It also delivers an array of additional features necessary in demanding broadcast and production environments, including setting for gradation, and selectable  colour temperature of 9300 K/6500 K/5600 K, or 3000 K to 9300 K.

Using SD SDI or video input, the LH1850 can display closed captions and supports both the EIA/CEA-708 HD-SDI and the EIA/CEA-608 SD-SDI closed captioning standards, and can display up to eight windows simultaneously. Like the monitor's waveform monitoring display function, the LH1850's vectorscope can now display all lines of the SDI input signal (Y/R/G/B). Various markers can be displayed in both 16:9 and 4:3 aspect ratios, including aspect (4:3, 13:9, 14:9, CNSCO 2.39, CNSCO 2.35, 2:1, and VISTA in 16:9 mode), safe area and centre. A simple cross hatch overlay can be displayed to check the tilt of the camera. The monitor's Pixel-to-Pixel function displays inputted video without any resizing, and a still frame display function can freeze a frame and display it as a sub-screen. The  colour audio level meter displays the input level of embedded audio, and a Time Code display shows the value of the VITC, LTC or UB time code. 

The LH1850 incorporates diverse video inputs and remote terminals to realize superb operability in a system configuration. Two SDI inputs (SDI1/SDI2) with an automatic HD/SD switching function are standard and support embedded audio. A next-generation HD Link is featured to allow high-quality connection of a wide range of digital HD products with an HDMI terminal, such as blu-ray/DVD players. Digital and analogue DVI-I (Single Link) input is also provided.

Its RS-485 Serial Remote permits up to 32 monitors to be connected in a loop-through configuration, each of which can be designated and controlled by a distinct ID number. TSL commands allow text display (8 alphanumeric characters) and tally indication. The monitor also supports unique Panasonic commands (equivalent to RS-232C).
