Superb Picture Performance
High Purity Color Filters
The LMD-1751W uses precisely manufactured RGB color fi lters,
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.
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.

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.
