Overscan: Image 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 1% to 10% of Overscan, as desired.

For HDTV, DVDs and other video sources, Overscan is generally not necessary or desirable.

Phase: Adjust the phase if the image from an RGB or Component source shows shimmer or
“noise.” Pixel phase adjusts the phase of the pixel sampling clock relative to the incoming
signal. The effect of this control is similar to that of a tracking control on a VCR.

For best results, use a good test pattern such as a smooth gray consisting of a clear pattern of
black and white pixels, or a similar “half on, half off” graphic image. (You may find that you
can stabilize the image at more than one point. Use either setting in this case.)

Memory Presets

For each input, the Vision 120 lets you save image quality settings as presets that you can
recall at a later time. You can create up to four presets per input and resolution. Use the ISF
Presets menu to recall saved image presets, or to save image settings in the “Custom 1” or
“THX” memory location. The currently-selected preset is indicated by a “

7

” to its left; in the

example shown here, ISF Night is selected.

You should save changes to any of the following settings to a preset; otherwise they will be
lost when a new input source or resolution is selected:

Brightness

Contrast

Color saturation

Tint

Sharpness

To reset the Custom 1 and THX image presets to their factory defaults, select Factory Default
and press ENTER or SELECT.
