FEATURES

■■Superb Picture Performance

High Purity Color Filters

The LMD-1751W uses precisely manufactured RGB color filters, allowing the reproduction of colors with stunning depth and saturation to create highly natural images.

Accurate Gamma and Stable White Balance

– ChromaTRU™ Color Processing

For an extra level of color-reproduction

accuracy, every LCD panel used in the LMD-1751W is precisely color calibrated at the factory, providing characteristics consistent with those of CRT displays. The colorimetry of an LCD display, by nature, can exhibit inaccurate R, G, B color coordinates and unbalanced R, G, B gamma curves, which can make precise color matching between multiple monitors a challenge.These are also the primary reasons why LCD color 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 color 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 color temperature throughout all grayscale levels.The result of these precise calibrations is excellent color reproduction reminiscent of Sony’s CRT displays.

Sophisticated I/P Conversion

The LMD-1751W uses a motion-adaptive I/P-conversion process to achieve conversion results that are optimized to the picture content – whether the image is static or dynamic. Highly accurate I/P conversion is provided regardless of signal resolution including both HD and SD inputs.

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 fi eld (0.5 frame).

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, color 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 LUMA monitors are adjusted at the factory to achieve optimized color, 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.

* The X-Rite Eye-one (i1) Series.

In addition, the LMD-2451W can be upgraded to support white balance calibration.
