OPERATION
To toggle between fast and slow sync, select item 5 from the Picture menu.
Item 5 indicates the current synchronization mode.
PIC 6 Blanking (Top/Bottom/Left/Right)
The Blanking selection item is used to hide or blank out unwanted information or noise at
the top, bottom, left, or right of the display image. Blanking adjustments may be required
when the source is a VCR or video signal.
To adjust blanking, select Blanking from the Picture menu. From the Blanking
menu, select item 1, 2, 3, or 4 to adjust the amount of blanking at the top, bottom, left, or
right of the display (respectively). A blanking slidebar is displayed for each adjustment.
A 0% level on the sliders indicates no blanking. For top and bottom adjustments, use
UP
and DOWN to adjust the amount of blanking. For left and right adjustments, use LEFT
and RIGHT to adjust the amount of blanking. After completing each adjustment, press
ENTER to return to the Blanking menu, or press EXIT to return to the picture.
PIC 7 Auto Clamp (On/Off)
The Auto Clamp function is used to turn automatic signal clamping on or off. For most
input signals, auto clamp should be on. However, if one or more of the red, green, or blue
color components is abnormally bright, turn
auto clamp off. An abnormally bright color
component can occur if the input signal contains more than one sync type (e.g., both sync
on green, and composite sync). If you are using a composite video source with VCR and
are connected to an RGB
interface, turn the Auto Clamp off.
To toggle auto clamp on or off, select item 7 from the Picture menu. Item 7
indicates the current Auto Clamp setting.
PIC 8 Retrace (Short/Long)
This function is used to set the projector's horizontal retrace time. Retrace time affects the
width and display of the picture. A short retrace time may be required if information is
missing or ''cut off'' at the left or right sides of the picture. A long retrace time may be
desired if the picture is significantly smaller than the raster.
To toggle between short and long retrace, select item 8 from the Picture menu.
Item 8 indicates the current retrace setting.
Notes: 1) Check phase, left blanking, and right blanking from the Picture menu before
changing retrace time. 2) Long retrace is not available at all scan frequencies.
PIC 9 Decoder Options
The Decoder Options menu item allows you to control the operation of the optional
Multi-standard Decoder.
