Motion Smoothness (5.38)


As it is near the bottom of LG's LCD lineup the LG 32LH20 lacks the higher refresh rates that tend to improve motion performance. As such we saw some significant motion blurring when viewing moving faces, colored blocks and patterns. That said, the motion blurring wasn't as bad as we might have imagined. Yes, fine detail was lost in the moving face, but it didn't turn into a complete blurry mess as we've seen on some other HDTVs, for example we could still easily make out the features of the face. There was significant trailing behind the colored blocks, however.

 

Motion Artifacting (4.63)


Artifacts are things that appear on your screen that should not be there, and are usually the result of problems with processing. The LG 32LH20 had some significant problems with motion artifacting. We saw an obvious rolling shutter effect, where white areas or complex patterns appeared to be moving up and down. We also saw some objects significantly warped by motion, with a stairstep effect appearing along the moving edges.

 

3:2 Pulldown & 24fps (5.5)


3:2 pulldown is the process by which a television takes broadcast content that arrives at 60 frames per second (fps) and converts it into 24 fps content. This is used to give you the film-like effect you want when watching movies. The LG 32LH20 has some problems with this process. We noticed some bright leading edges and shuttering with moving patterns as well as a "crawl" effect. If you have content that arrives natively at 24 fps, such as from a DVD or Blu-ray, the LG 32LH20 is able to handle that.
