PICTURE CONTROL
Zoom
Choose Zoom when you want to view the picture
without any alteration. However, the top and
bottom portions of the picture will be cropped.
Just Scan
Normally the edges of video signals are cropped
1-2%. Just Scan turns off this cropping and
shows the complete video.
Notes: If there is noise on the edges of the original
signal, it will be visible when Just Scan is activated.
Just Scan operates only with
DTV/CADTV/HDMI-DTV/DVI-DTV
(720p/1080i), Component(720p/1080i) input
sources.
