LMD-1751W
Professional LCD Monitor
The monitor stand is optional.
Inheriting the vital functions and performance of Sony's highly acclaimed LMD Series professional monitors, the LMD-1751W is the latest enhancement to this series, an outstanding new high-grade LCD video monitor. The LMD-1751W is a 17-inch (431 mm)*1 multi-format, rack-mountable HD video monitor, incorporating a wide viewing angle LCD panel, high-purity colour filters, sophisticated 10-bit signal processing, and Sony's unique ChromaTRU*2 colour matching technology. With these qualities, the LMD-1751W delivers precise images and accurate colour reproduction for professional video monitoring. Added to this, a newly supported white balance calibration function*3 allows quick and simple monitor adjustment and matching. Another advantage of the LMD-1751W is its 3G-SDI interface. Using an optional 3G-SDI input adaptor, the BKM-250TG, Y/Cb/Cr 4:2:2, 1080/50P and 1080/60P signals are accepted with a single cable. , With the strength of Sony's video expertise, the LMD-1751W is sure to meet a wide variety of picture monitoring applications from broadcast and post-production to event production and mobile truck installations, in both AC and DC operating environments.

FEATURES Superb Picture Performance
High Purity Colour Filters
The LMD-1751W uses precisely manufactured RGB colour filters, allowing the reproduction of Colours with stunning depth and saturation to create highly natural images.
Picture Delay Minimum Mode
Audio is just as much a part of the show as video, and timing is always an issue. Picture Delay Minimum mode is selectable to minimize I/P conversion times for audio synchronization during editing. By selecting "LINE DOUBLER" under "IP MODE", the signal processing (I/P conversion) period is less than one field (0.5 frame).

Accurate Gamma and Stable White Balance ChromaTRUTM Colour Processing
For an extra level of colour-reproduction accuracy, every LCD panel used in the LMD-1751W is precisely colour calibrated at the factory, providing characteristics consistent with those of CRT displays. The colourimetry of an LCD display, by nature, can exhibit inaccurate R, G, B colour coordinates and unbalanced R, G, B gamma curves, which can make precise colour matching between multiple monitors a challenge. These are also the primary reasons why LCD colour tone can differ slightly from CRT tone. The LMD-1751W solves this problem by precisely calibrating each LCD panel's light output so that the R, G, B colour coordinates are virtually the same as those of a CRT monitor. A second calibration is further applied so that white balance is maintained at a consistent colour temperature throughout all grayscale levels. The result of these precise calibrations is excellent colour reproduction reminiscent of Sony's CRT displays. CIE Colour Coordinates

Extremely Wide Viewing Angle
The LMD-1751W offers stable images when viewed from various angles. It delivers wide viewing angles both horizontally and vertically, with virtually no reduction in picture contrast, colour saturation, or hue shift. This allows precise images to be clearly viewed from various positions and angles a critical requirement in professional video monitoring.

White Balance Calibration Function
High-grade LMD Series monitors are adjusted at the factory to achieve optimized colour, brightness, and gamma prior to shipment. LCD monitor performance, however, typically changes over time and requires regular recalibration to maintain its original performance. The LMD-1751W employs a software-based white balance calibration function, which is called AutoWhiteBalance. Combined with a commercially available calibration tool*, this function enables simple adjustment of the monitor's white balance.
