Over Scan Adjust: Overscan pushes the outside edge of the active picture area of the
video signal out beyond the edge of the display area.
Some television programs are produced based on the assumption that older television
sets may not display the outer edges of the broadcast picture area. Over scan effectively
trims away these inactive, outer edges and enlarges the remaining portion of the image to
fill the display area.
Select from 0% to 10% of Overscan, as desired.
For HDTV, DVDs and other video sources, Overscan is generally not necessary or
desirable.

• Chroma Enhance: Use Chroma Enhance to add chroma (color information) to the
input signal, making colors appear more vibrant and saturated.
• Video On Film: Set Video On Film to ON to repair distortions or abnormalities in a
video image.
• Film Mode: Use the Film Mode control to smooth out moving images from interlaced
sources. In most cases, the CL-410/CL-420 detects the proper "pull-down" rate and
vertical frequency. However, if your source is jittery and/or tearing you may wish to
force a setting to ensure stable processing for that source.
Brightness Enhance: to amplify the bright areas of the image, select Brightness
Enhance and use the right- or left-arrow button (
Enhance can be useful for high ambient light environments or when you use the lower
Lamp Power setting (see below).
Lamp Power: Select Lamp Power from the Display Color Menu to adjust the lamp output
level. You can choose to run the lamp as bright as possible (250W; this is the default
setting) or you can choose the lower setting (200W). Generally, lower lamp output can
prolong the life of the lamp, but decreases brightness.
