Motion Smoothness (5.25)

The JVC LT-42P300 had some significant problems with motion smoothness. When looking at a complex pattern moving like a human face you lose almost all detail, it just turns into a blurry mess. More uniform objects displayed some significant blurring behind them as well. This just isn't going to be a television that's going to handle the fastest action sequences without a problem.

Motion Artifacting (5.13)

Artifacting refers to things that appears on the screen that shouldn't be there. The JVC LT-42P300 displayed several artifacting problems with motion. We saw a significant shutter effect with certain patterns and scenes, especially when the television is handling a 1080i signal. We also saw glowing bars along the edges of certain solid moving objects, an indication that the HDTV is seriously cranking up the contrast ratio to attempt to keep up with motion.

3:2 Pulldown & 24fps (7.5)

3:2 pulldown refers to the process that HDTVs use to convert content they receive at 60 frames per second (fps) to a more film-like 24 fps. This process is used for broadcast HD signals that always come in at 60 fps that should be shown at 24 fps, for example movies. The JVC LT-42P300's handling of this conversion is solid, with the rather unfortunate caveat that you need to turn on the Natural Cinema feature in the menu to enable this function. Leave it off and you get problems with flickering. The annoying part of this is that you have to guess when you might need the feature, as we mention above this process is usually used with broadcast HD and there's no indicator on the broadcast that tells you the feature is needed. Most HDTVs do this conversion automatically as such we deducted a point from the LT-42P300's score in this section. If you've got native 24fps content from something like a DVD or Blu-ray disc the LT-42P300 supports that as well.
