Auto in “Zoom”
What is “Eco Sensor”?
DarkLight
Most conventional LCD panel uses 50 frames per second (50Hz) or 60 frames per second (60Hz) to display an image which needs long holding time (time it takes to display single frame), causing blurring or ghost images when there is rapid or complex movement across the screen – a phenomenon common to all LCD panels.
This TV is equipped with JVC’s original “Clear Motion Drive u” technology, which displays two frames (the original plus the new interpolated frame) in the time a 50Hz or 60Hz set displays a single frame. Resulting to double the typical rate, 100 frames per second (100Hz) or 120 frames per second (120Hz) and halve the holding time without reducing brightness or contrast. By using this technology you will be able to reduce blurring or ghost images when there is rapid or complex movement across the screen.
By using “Demo 3”, you can display the differences between conventional LCD (50Hz or 60Hz) and LCD panel equipped with “Clear Motion Drive u”.
Clear Motion Drive u
*1 To simulate Moving image of conventional LCD, the TV will display two same frames at a time.
Note : The illustrations are emphasized to make clear differences between LCD panel equipped with “Clear Motion Drive u” and conventional LCD.
Set “Auto Demonstration” to “On” / “Off ”.  “Auto Demonstration” (P. 34)When set to “On”, it automatically enters demonstration every time no operation is made for approximately  3 minutes. To stop automatic demonstration, set “Auto Demonstration” to “Off ”.When the images are 60 frames per second (60Hz), it will be produced as 120 frames per second (120Hz).
