“100Hz” technology provides superior solutions for 
digital display picture quality removing motion blur.

This effect is greater on fast moving images.
“100Hz” will have no effect in the following cases;
1) The type of signal received is a PC signal.
2) An OSD is being displayed.
3) Teletext is activated.
If images appear blurred, set the “100Hz” to “Off”.

Automatically detects a film-based source (originally encoded 
at 24 or 25 frames per second, depending on the vertical 
frequency), analyses it and then recreates each still film frame 
for high-definition picture quality.
