Motion Smoothness (7.25)


If you're going for smoothness, you have to turn on the TruMotion 240Hz feature. Without it, we saw significant blurring on our test pictures. Solid blocks of color tended to trail slightly, but not any more than the average HDTV. When we performed the same tests in 1080i, we noticed a decrease in blurring.

Motion Artifacting (6.25)


We didn't see troublesome artifacting in 1080p playback. Edges and fine patterns had a rolling shudder effect, but it wasn't particularly pronounced. The same wasn't true for 1080i playback, which had some significant artifacts with alternating black-to-white gradients. The thinner strips would flash in sections. Turning off TruMotion 240Hz helped matters by blurring everything to such a degree that the flashing wasn't noticeable, but this obviously isn't an ideal solution.

With the exception of that one major artifacting issue, the 37LH55 did well on this test.

 

3:2 Pulldown & 24fps (8.50)


For 24 fps you're going to want to turn off TruMotion 240Hz. This will cause some significant artifacting issues in fine patterns. We tried enabling and disabling Real Cinema mode, but it didn't seem to add or subtract from picture quality.

The 37LH55 did well on our tests once TruMotion was turned off. There was still a slight crawling effect over fine patterns, such as empty stadium seats, but nothing major.
