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


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 analog 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).
