• Change PIN: The default PIN for accessing the parental controls or bypassing content
restrictions is 0000. Vidikron recommends changing this to something less obvious.
Letterbox Mode: Select Letterbox Mode from the
Setup menu to change the zoom factor that takes effect
when you select the Letterbox aspect ratio (refer to
Table 4-1).
When you select Letterbox, the image is enlarged
(zoomed in) by a factor of approximately 1.33.
When you select Cinema Fill, the zoom factor is
approximately 1.77 (1.33 x 1.33).
Input Selection: Input 1 and Input 2 have both S-Video and Composite video connectors.
Input 3 and Input 4 have both Component and Composite video connectors. To specify
which connection type you are using – or to switch from one to the other if equipment is
connected to both – select Input Selection from the Setup menu and press ENTER.
The default setting for all four AV inputs is Automatic. With this setting, the DView searches
for an active source on both connectors and displays the first one it detects. If equipment is
connected to both, Automatic input selection triggers a switch when a source component is
disconnected or powered off.
Monitor Out: If you have equipment connected to the AV OUT, select Monitor Out from the
Setup menu to route either the main or PIP audio/video signals to that output.
Overscan (not available with PC signals): 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. Overscan effectively trims
away these inactive, outer edges and enlarges the remaining portion of the image to fill the
display area.
Use the on-screen slidebars to set the desired amount of horizontal and vertical overscan, as
well as horizontal and vertical image shift.
These settings only affect 480i source material. For HDTV, DVDs and other video sources,
Overscan is generally not necessary or desirable.
Input Label: You can give each DView input a descriptive name. To do this, select Input
Label from the Setup menu and choose one from the list.
HDMI Audio: If the HDMI source is a PC or other device that does not support audio output
via HDMI, set HDMI Audio to PC.
If the source does support audio output via HDMI, set this option to HDMI to route the HDMI
(digital) audio signal to the speakers when HDMI1 or HDMI2 is selected.
RGB Signal: The RGB input supports both DTV and VESA (computer) resolutions and signal
timings. If the RGB source is a computer, select PC. If it is a DTV set-top box or other
equipment with an RGB output, select Video.
