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.
Decoder Options
The Decoder Options menu item allows you to control the operation of
the optional Multi-standard Decoder.
To modify decoder operation, select Decoder
Options from the Picture menu. From the Decoder
Options menu, select item 1 to set the decoding
method to use for the current source signal input to
the decoder. Select item 2 to set the routing of the
current source signal within the projector.
Video Standard
When item 1 is selected from the Decoder Options
menu, the Video Standard menu is displayed. It
contains up to eight video standard options: Auto-
detect, NTSC 3.58, NTSC 4.43, PAL, SECAM and,
depending on which version of the decoder is installed,
three more PAL options (see right). The current option
is indicated by a check mark. Auto-detect is the default.
When “Auto-detect” is selected, the decoder automati-
cally determines the video standard of the input signal
and processes it accordingly. Alternatively, you can
force the decoder to use a particular decoding method
by selecting one of the other menu options. This should
only be necessary for poor quality input signals.
