LMD-1751W

Inheriting the vital functions and performance of Sony’s highly acclaimed LUMA 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)*
wide viewing angle LCD panel, high-purity color fi lters, sophisticated 10-bit signal processing, and Sony’s
unique ChromaTRU*

color matching technology. With these qualities, the LMD-1751W delivers precise
images and accurate color reproduction for professional video monitoring. Added to this, a newly
supported white balance calibration function*

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.

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.

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

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.
