JVC's innovative LCD monitor LT-42WX70 can satisfy digital imaging professionals and enthusiasts using high-end digital SLR cameras, allowing them to enjoy the subtle colours, details, and textures of their own images faithfully reproduced on a large 42-inch screen.

Such faithful reproduction can be achieved with the adoption of JVC's original panel with wider colour space, the monitor's ability to match the colours to the source, and gamma curve adjustment without individual difference.

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 still photographs ― the user can select from one of six available colour spaces: Wide (the LCD monitor's colour space), Normal (ITU-R BT.709, HDTV standards), x.v.Colour (xvYCC extended gamut), Auto (either Wide or x.v.Colour) for viewing video sources, sRGB (same primaries as HDTV) and Adobe RGB for viewing digital photographs.

The LCD 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 bluish greens, which are typical characteristics of the Adobe RGB colour range.

Chromaticity Point Conversion Circuit matches the Colour to the Source

On a conventional LCD monitor with wider colour space, attempting to display images with different colour spaces can cause bleed and drift due to gaps between the source colour format and the LCD's colour space. To overcome this, the new DynaPix Picture Engine features a Chromaticity Point Conversion Circuit that employs an original algorithm and RGB processing (same primaries as the panel) to better match colours to the source ― regardless of video or stills ― without reducing the number of displayable colours to ensure deep, natural and accurate image reproduction. This means that still photographs taken using Adobe RGB and displayed on the LT-42WX70 in the Adobe RGB colour space will be reproduced with colours faithful to the original.

Chromaticity Point Conversion Circuit

DynaPix Picture Engine's Chromaticity Point Conversion Circuit (see below diagram) with an original algorithm converts YUV signal back to RGB for accurate RGB processing, the same primaries as the LCD, to match the colours to the source without reducing the number of displayable colours thereby yielding deep, natural and accurate images.

Individual Gamma Curve Adjustment

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.
