Viewing Effects Summary
• Very poor viewing angle
• Only a handful of video processing features, and most make no difference

Viewing Angle (5.23)


The LT-42WX70 was a little disappointing in terms of the viewing angle; we found that the contrast ratio of the display fell to 50% of the maximum at just over 20 degrees off axis, which is a rather low number. Other HDTVs had much wider viewing angles: the similarly sized JVC LT-42P300 had a viewing angle of just under 35 degrees, meaning that you would still get a decent picture even if you were off-center from the middle of the screen.

Viewing Angle Comparison

 

Reflectance (6.25)


Although reflections are visible in the screen of the LT-42WX70, they aren't a big problem; there is a coating on the screen that diffuses them slightly so they are more splotches of light than reflections. We'd still recommend that you place the screen carefully so that there are the minimum of reflections in it, though; we still found them to be somewhat distracting

 

Video Processing (3.0)


As the LN-42WX70 does not have a cable/antenna input, it is missing many of the video processing features present on other TVs that are designed to try and improve a poor signal. There are a few other video processing features, though, which are detailed below.

Setting Claimed Function Our Impression
Sharpness Enhancer "Selects the frequency band enhanced by Sharpness" Modes 1 to 6. We didn't see much difference in any of the modes. 
Color Matrix "Selects the colour matrix used for colour conversion." Shifts the colors based on the color spaces for HD and SD video.
Picture Management "Adjusts gamma value automatically depending on the brightness of
pictures."
Boosts shadow detail in dark video.
Digital VNR "Reduces picture noise" 3 levels: low, medium and high. Reduced noise slightly with noisy source material.
MPEG NR "Reduces noise on MPEG pictures such as mosquito-noise and blocknoise." Reduces noise very slightly.


As usual with features like this, most are not worth bothering with; you'd be better off spending time improving the quality of the source rather than fiddling with them to get the right set of settings.
