The 50PS60's THX Display Certification ensures exceptional viewing experiences, while 600Hz Sub-Field Drive technology reproduces video with heightened realism by flashing the plasma panel's pixels 10 times for each frame of TV or movie content. Four HDMI inputs and two HD component video inputs give you multiple options for getting HD video to the full HD 1080p panel. While Clear Voice II technology enhances movie and TV dialogue, an Invisible Speaker system lends this LG plasma panel a more compact, less obtrusive footprint.
