Motion Smoothness*(8.0)*


The Samsung UN46B7100 supports a 120Hz refresh rate, which is twice the standard 60Hz. LCD manufacturers have been increasing refresh rate in an attempt to reduce motion blur, with some televisions up to 240Hz now. On the Samsung UN46B7100 the 120Hz refresh rate seems to help significantly reduce motion blur. The blur reduction tool can be tweaked along a scale from 0 to 10. You can also adjust judder reduction in the same way.

Motion Artifacting*(7.0)*


Unfortunately the Samsung UN46B7100 didn't do as well with motion artifacting as it did with motion blur. Artifacts are things that appear on the display that shouldn't be there, usually due to a processing problem. The biggest problem with the Samsung UN46B7100 in this area was a very obvious rolling shutter effect, which is noticeable in white and black areas of the display. We also saw some areas of leading and trailing brightness that shouldn't be there.

 

3:2 Pulldown & 24fps*(7.5)*


3:2 pulldown refers to the process by which an HDTV takes a broadcast signal that comes in at 60 frames per second (fps) and turns it into a 24fps image. This is necessary when you are watching a film that should be displayed at 24fps to give it that film-like look. The Samsung UN46B7100 did a decent job of this. We look at a test pattern and noticed only minor errors due to processing. When looking at test footage we noticed a slight 'jaggy' effect on the screen, but nothing major. The Samsung UN46B7100 is also capable of handling native 24fps content that comes in from a DVD or Blu-ray player, although we should mention that you probably want to turn off the 120Hz refresh rate when watching such content to retain the film-like look.
