Motion Smoothness
(6.75)


The LT-42WX70 includes a 120Hz refresh rate, and this made a significant difference in the smoothness of motion; we found that with this enabled, motion was  much smoother. However, there were still some issues: faces and other complex objects on screen took on a flat, cartoonish look and lacked definition.

 

Motion Artifacting (6.5)


We also saw some issues with sharp edges; our test screen of a number of white to black edges moving rapidly across the screen had an unpleasant, juddering look to it, with the edge becoming broken and jagged. This was also noticeable on real TV images; if an object moved rapidly across the screen, it took on a broken, jagged look.

 

3:2 Pulldown & 24fps (5.0)


The LT-42WX70 had some problems displaying an image using 3:2 pulldown processing; in our test screens we saw strobing that indicates it couldn't fully process the signal, so you won't get the full effect of the filmic look that 3:2 processing tries to create. It did not, however, have any problems handling a 24 frames per second signal from a Blu-ray player.
