It is truly no exaggeration to say that the LT-42WX70 is special TV made for digital SLR camera users. A digital photograph displayed on the large 42-inch screen with faithfully reproduced colours is not only impressive but also provides an added sense of accomplishment and satisfaction to the person who took the original image.
JVC Original Panel with Wider Colour Space
The LT-42WX70 features a colour space that is wider than an HDTV and depending on the source signal ― video or stills ― the user can select from a colour mode of Wide (the TV's colour space), Normal (ITU-R BT.709, HDTV standards), x.v.Colour (xvYCC extended gamut), sRGB (same primaries as HDTV) and Adobe RGB. The sRGB and Adobe RGB colour spaces are exclusively used for viewing digital still images and if the photographer takes the shot by selecting the Adobe RGB setup, then the same Adobe RGB mode should be set on the monitor to ensure that the image is reproduced faithfully to its original colours. The monitor also encompasses 100% of sRGB colour space (which is equivalent to HDTV for the video signal) as well as a coverage rate of 96% for Adobe RGB. The LT-42WX70 can accurately reproduce deeper reds and blues as well as more vibrant greens, which are typical characteristics of the Adobe RGB colour range.

Differences between coverage and area
Looking at the diagram, if we take the blue triangle as Adobe RGB and the yellow triangle as a TV's colour space, the areas of both triangles are the same, so 100%. However because the yellow one doesn't cover the entire blue space, overlapping area is only about 90% coverage. The LT-42WX70 has an area ratio of 117% for sRGB and 100% for Adobe RGB.
Individual Gamma Curve Adjustment Prior to Shipping
JVC's original Individual Gamma Adjust System calibrates each panel's grayscale tones to gamma 2.2, ensuring the display of consistent and faithful colour reproduction regardless of the set or manufactured lot. This extra benefit was incorporated because colour consistency between the source and display is essential when reproducing photos that are taken on digital SLR cameras or video from different sources.
The gamma curve for each primary colour (R/G/B) has to be accurate to ensure correct white balance and gradations.
Reproduction is faithful to the original.
“Photo Pro” Preset ― Optimally Designed for Displaying digital SLR Photographs
The LT-42WX70 features six presets that can store user-preference picture modes to ensure higher picture quality for both movies and stills. Of the six presets, “Photo Pro” Preset is designed for displaying digital SLR camera images to enable the faithful and accurate reproduction of the source image.
Conventional TV
It is not possible to distinguish the subtle gradations in these flower petals because they appear saturated on a conventional TV.
