Samsung LN46A750 LCD HDTV Review - Performance: Motion

The LN46A750 generally did did an excellent job of producing clean, smooth movement, even in our video sequences that have lots of movement. The display also did a very decent job of displaying both 24 frame per second video and 3:2 pulldown processing, such as TV shows that want to look like movies.

Motion Smoothness (7.75)
The Auto Motion Plus 120 Hz processing mode of the LN46A750 did a very creditable job of smoothing out motion, getting rid of the jerky, juddering effect that you often see in fast-moving scenes. However, it is not without a price; it creates a rather flat, almost abstract cartoonish look to some videos when put on maximum. It's perhaps a question of taste; some will prefer the smoth movement, while others will find the flat color more distracting.

Motion Artifacting (8.25)
As we mentioned above, the motion processing of the LN46A750 has a price; the rather flat looking color. We did not see any evidence of other artifacts, though; there was little or not chopping or other glitches, even on scenes that had a serious amount of movement, such as the first monster attack scene in Cloverfield. Hope we didn't spoil the movie for you there.

3:2 Pulldown & 24fps (8.5)
All movies and many TV shows are shot at a frame rate of 24 frames per second, then converted to the 29.97 frames per second of a TV signal using a process called Telecine. Many displays can detect this and try to restore the filmic look using a process called 3:2 pulldown. The LN46A750 is one such display, and it did an excellent job of detecting the telecine effect and processing it to reproduce the filmic look of the origional. You can also turn this effect on or off; the display calls it film mode. The LN46A750 also did a nice job of rendering a 24fps video source (we use a Blu-ray movie and a PS3 set to output a 24fps signal), producing a clean image with smooth motion.
